18/04/2013: Kx-PolyMod, version 1.54:
Fixed bugs:
- The S=0 envelop option could generate audio clicks with a short release time.
- The decay and release times were modified by the sustain level. A selector has been added to preserve the compatibility with the actual presets.
- Possibility of bug with the Fx2 synchronized with a very low host tempo.
- The Fx decay is now based on the synthesizer output and on the midi input to avoid to stop the Fx with a short decay when the Vca envelop is synchronized with the host tempo.

*This version replaces the 1.53 (18/04/2013) with a bug when the sustain is to 0 (sorry for that...).

24/03/2013: Kx-PolyMod, version 1.52: 
Improvements:
- New SFO compatible with the PAN feature of SF2 banks.
- New SEM modules compiled with SSE2 feature, up to 7% CPU won (min requirements >= Athlon K8 and P4).
- Improvement of the loading of large SF2 banks.
- Vcfs: possibility to replace the "Master Cut" (F1 and F2) by a simple Cut off (F1).
- Improvement of the Fx: new sources of modulation, new SV filter (2 to 4 poles), dry level added.
- Filter Fx: now it is not necessary to set the resonance to half in LP mode to have a flat response curve.
- Peak follower added to smooth the Sample and Hold signal.
- Some automation names corrected.
- All notes are stopped when the selectors "P Max" or "P Note" are modified.
Fixed bug:
- The plug-in could be overloaded when the distortion was oversampled, if the sustain level, the release time of the Vca Eg were set to 0 and also when the Pan was on the left or on the right (too small signal level to the oversampled distortion).

31/12/2012: Kx-Midi-Filter, ver 2.0:
- Possibility to transpose the Midi input notes and to play on the virtual keyboard (9 octaves).
- Pitch Bend and Modulation wheels.
- Adjustment of the velocity.
- Only one program.
- Reset.
- New skin.

18/11/2012: Kx-PolyMod, version 1.51: 
Fixed bug:
- The delay time of the FX2 was false (divided by 60) when it was synchronized by the host.

09/11/2012: Kx-PolyMod, version 1.5: various improvements and new filters added, including those of the CS70M.
- Better reset of the voices (filters and oscillators).
- Now, the levels of the harmonics before the cut off do not decrease when the resonance is high (lp or bp, 18,12, 6).
- A soft Tanh process has been implemented in some d* filters, the signal is modified by the Tanh process following the input level. This is similar but produces less distortions.
- Four SV filters (lp, hp, bp, notch) added with the possibility to adjust the number of poles of the slope (2 to 4, 12dB to 24 dB).
- Two CS70M filters added (lp, hp), a special version of the SV filter with the same limits found in the tests: the cut off limited to 7040hz (9 volts) and the resonance level limited to 0.88.
- A GUI tool added: you can change the joystick background color to identify your plug-in if you have a session with many plug-ins used.
- The internal help texte has been modified to correct some errors and to update the test values.
Fixed bugs :
- The cut off of the MgL2 filter was false, the values used were not those of the oversampled filters.
- In some cases, the F1-F2 mix multiplied the stereo Vcf output by 0, doing an anormal CPU use.

02/09/2012: 02/09/2012: Kx-PolyMod, version 1.02
- The bank has been completed with 34 presets, a lot of them use the Vco1 synchro.
- The amount of the Kxmod random values has been divided by 4.
Fixed bug:
- Some drum kits of the "Titanic" soundfont bank (230 mo) could crash the host when they were changed with the SF2 selectors and the EGs were synchronized by the host. The selectors have been deleted to avoid this bug but you can alway select the sf2 instruments with the menus.
To avoid to use too much memory with large soundfont banks, you can use the free sf2 editor "Viena" provided by:
http://www.synthfont.com

12/08/2012: Kx-PolyMod, version 1.01
Fixed bug:
- Some filter processes could overload the plug-in when the resonance was set to max and the Vcf outputs were modified with the St button.

11/08/2012: Kx-PolyMod
28 presets added and the internal help text has been modified.

06/08/2012: New plug-in, Kx-PolyMod, ver 1.0
It is a new analog modular synthesizer with SF2 player, a mix between the Kxpm and the Kx-Synth-x16...
I wanted to update the Kxpm23 but finally I built a new plug-in. 5 months of work!
The presets are very vintage, include Mini and CS leads.
A little drum set of 12 instruments in 24 bits (3.3 mo) is provided inside the setup or the zip.

25/02/2012: KX-SYNTH-X16 update, ver 4.3
- Improvement of the KXMOD modularity, the levels of the inputs (1, 2) can be modfied for each voice.
- Now the waveform selectors are not controlled by the Program Change and if you replace the initial waveforms by these of the Kx-Modulad all presets which use them will be modified.
Fixed bug:
- The short Asio buffers were dropped when the program change if a sequencer file was loaded.

Infos : V4.1 and upper with Zynewave Podium
The plug-in must be imported manually (or with drag and drop) in the vst database because the automatic scan doesn't recognize the V4 perhaps that it is a Vsti with 4 outputs (Poly and M versions).
You must save your plug-in database in you project or in a template.
Any way with the older versions (4.0 and 3.0-3.3) the the plug-in was loaded with a bad setting of the outputs and it had be changed by the user (quad outputs) who thought generally that it was a bug...

01/01/2012: KX-SYNTH-X16 update, ver 4.2
- Improvement of the matrix modularity, now the volume control inputs can be replaced by Pan or Shape control inputs.
- Several sources to the FX modulation have been added.
Fixed bugs:
The joystick values were wrong when the offset of -10 to 10 was selected (M and FX versions).

24/12/2011: New VSTi Midi plug-in, Kx-Midi-Filter, ver 1.0
It is a Midi tool to filter and merge the following Midi data: Channel, Velocity, Prg Change, Note, Bender, After, Poly After, CC (mapping is also available to 5 of them). The notes are monitored on a keyboard and the Midi messages are monitored on a screen. A total of 36 parameters saved in bank of 128 presets.

19/12/2011: KX-SYNTH-X16 update, ver 4.1a
- Improvement of the Midi Learn, now it's not necessary to sustain a Midi note which is used to control a button, just to play it again to stop the control. Useful to control the sequencer on/off (Pause button) with a Midi keyboard.
- A selector has been added for the Midi Learn channel.

04/12/2011: KX-SYNTH-X16 update, ver 4.1
- Improvement of the matrix modularity,  the In1, In2, X Mod, Y Mod matrix sources have the same choice of modulations (new: Vca Env are also included). The X Mod and Y Mod sources can modulate the Ring Modulator.
- The joystick has now two offsets, 0 to 10 or -10 to 10.
- Peak follower on audio inputs and Midi output added on the FX version.
- Possibility to hold the trigger button, a way to put the effect alway on (Fx version).
Fixed bugs:
- The audio inputs are muted (4 sec) when the initialization of the plug-in (FX version).
- The Midi input channel was always set to All and its selector followed the program change.
- The bug of the audio outputs with Zynewave and Sonar has been fixed.

11/11/2011: KX-SYNTH-X16 update, ver 4.0
- Now the built-in sequencer is polyphonic with 6 tracks of 256 steps. They are 6 data per step: cv, gate state, accent 1, accent 2, length, trigger2. All of these data are saved on the hard disk. More possibilities to synchronize the sequencer with the host. The old files *.x16 are compatible with this new version.
- Improvement of the ring modulator with 4 new limiters (oversampled).
- An hermite interpolator have been added to the delay.
- Possibility to transpose the vcos directly with pop-up menus.
- A bank of 32 new presets is provided with the plug-in (160 KX's presets).
- All sequencer presets has been rewritten.
Fixed bugs:
- A management of the output signals (left, right, meter) has been added to avoid the Sonar X bug.
- Strong entries of the pitch values could crash the frequency displays, each display is limited now.

23/04/2011: KX-SYNTH-X16 update, ver 3.3
- Vco1 improvement when it is synchronized by the Vco2 with the possibility to reduce the high frequencies modulations.
- Possibility to verify the Meter signal (all voices) before its ouput level and now the Meter output level is not linked with the Midi Prg Change.
- The Vca knob controls the vca level when the Mod envelop is used to modulate the vca level.

23/04/2011: Kx-Modulad update, ver 2.3
- Vco2 improvement when it is synchronized by the Vco1 with the possibility to reduce the high frequencies modulations.
- SF2 player improvement with the possibility to choice if the samples change following the pitch or not (Mod), useful for SF2 drum sets.
Fixed bugs:
- Now the probability to have audio clicks at the end of no looped sf2 samples is very low, tested with various sf2 banks.
- The buffer size of the delays has been decreased to 5 sec to avoid a crash when the amount of the modulation is at max.

11/2010: The KX-SYNTH-X16 has been selected by Computer Magazine,

Author's note

I have been programing synthetizer presets for many years. The VST plug-ins that I propose are a series of instruments that use evolved subtractive synthesis. They are not simply a numerical emulation of vintage keyboards.

With the KX77FREE plug-ins, the musician is not limited to the vintage sounds. The structures of the KXOMNI 600 and the KX-MODULAD plug-ins are more advanced. They permit to create more acoustic sounds and also fat pad sounds. The KXSTEP and the KX-SYNTH-X16 sounds are really more 70's.

My work is maybe a little different than usual virtual synthesizers, but it is done for the attention of musicians who like to program their own sounds. Even if I explain clearly the KXMOD parameters use, you must have a minimum of knowledge of subtractive synthesis to appreciate them. The sounds provided with my plug-ins are examples but the presets of KXOMNI, KX-MODULAD and KX-SYNTH-X16 are really nice...

I started to work on KX77FREE plug-ins in October 2002. Comparing the sound obtained with Synthedit and with my SixTrack, I decided to do my own virtual instruments.

The first advantage of developing VST plug-ins with Synthedit is that its modules (vco, vcf, vca...) are controlled by voltage. e.g. if you modulate an oscillator with a value of 5 volts you obtain 440 Hz. We stay in the logic of analog synthesizers and the behavior of the various modules of Synthedit is close to their hardware equivalent.
The second advantage is that you can do a simple and effective programming. The programmer can concentrate his attention to the musical aspect of the instrument.

But the power of this program is in the possibility of writing its own modules with the C++.
Since May 2005, I started to write my own modules.
They are now built-in into the KXOMNI 600, KX-MODULAD, KX-SYNTH-X16 and KX-POLYMOD plug-ins. Without Synthedit I would not have imagined to create these plug-ins, too complex to be programmed entirely in C++!

I have been often disappointed by the sound quality of the virtual analog synthesizer plug-ins. Most of these plug-ins do not reproduce the sound of analog synthesizers of the Seventies and Eighties. They are far from having an equivalent sound. Even if they reproduce the vintage synthesizer architecture, they have not the typical sound of these electronic instruments which are so much appreciated by a whole generation of musicians.
I do not claim to do better. Do not dream, if you want the sound of a vintage keyboard, buy one!

I have already exploited and tuned this kind of machines. I think that simulating the characteristic tune defects of vintage keyboards is not technically difficult. The purpous is not to reproduce each transistor and resistance of an analogic circuit, but to create similar defects, the most significant, those that flatter our ears. This way, you avoid spending the resources of the processor, these are thus dedicated to the structure of the instrument.

In fact, it is not interesting to make a simple imitation of "Moog". It is better to build synthetizers which were impossible to realize at the vintage time (too high cost), staying in the same spirit, by improving each group of parameters to realize instruments as musical as possible.

I worked on the possible solutions to simulate the sound of the analog synthesizers and to create new parameters adapted to the music of today.

These solutions are the parameters named KXMOD*.

The principle is: the user can create modulations of the voltage of the oscillators and filter in order to simulate the defects of analog synthesizers. However, the user has the possibility of not using them.
The KXMOD parameters are not really innovating (they are just where they must be...) but the musician can create with them more musical sounds. And following the plug-in these parameters may change.

At the beginning, I did not intend to provide my plug-ins on Internet, but as I am enthusiastically in favour of free softwares and realizing the quality of the sound obtained with Synthedit, I decided to finish my plug-ins and to provide them free.

Currently, the KX77FREE plug-ins are distributed as FREEWARES.

In return, I would like to have your opinion about my plug-ins to ameliorate them. And as soon as possible if you like them, you can talk about on the web forums. I try to keep my time for the development.

Helps and Advices

Compatibilities
Unfortunately these plug-ins are not compatible with APPLE*. They are VST 2.3 plug-ins and they work with all recent systems of Windows.
SE plug-ins are compatible with all hosts which are VST 32 bits compatible (with a 32 bits bridge like the 64 bits versions of Cubase or Reaper) for Windows 32 and 64. They were tested with all major hosts like Cubase, Energy Xt, Orion, FL, Live, Reaper, Samplitude, VstHost.
*You can use VFX to use these plug-ins in standalone on Mac Intel or Wine on Linux.

Help tips
The knobs of Kx77free plug-ins have help tips (in english) to explain the new functions incorporated in these plug-ins. It will be easier to you to control all the KX77FREE plug-ins if you start with the KXPM23. It has two colors of knobs, red for the standard parameters, blue for the new functions and the complex modulations.
The KX-MODULAD, KXSTEP, KX-PLYMOD and KX-SYNTH-X16-V4 have a help file built-in, push on Help button to read it.

The KX77FREE plug-ins are provided for experienced musicians. I highly advise the beginners to download Synthedit and to use the synthesisers provided with it : www.synthedit.com

Support
The KX77FREE plug-ins are stable VST 2.3 and they have been used several months or years ago. They were compiled with stable versions of Syntedit (1.016, 1.1 for the last plug-ins).
They were built only with SE and KX77FREE's modules. A good way to avoid a lot of bugs and it's usefull for the updates!
All vst programs are not 100% compatible, for example some do not manage the midi entry of the vst effects or the multiple outputs...
A bug can have several causes: the Asio driver, the host program, the engine of Synthedit, my modules and finally the structure of the plug-in. I can modify the structure of my plug-ins, compile my plug-ins with the new versions of Synthedit or modify my SEM modules (written in C++).

PLEASE CONTACT ME IF YOU FOUND A BUG! The KX77FREE plug-ins updates are done *** freely ***.

A modular plug-in is not a simple synthesizer with a limited number of modulations! Sometime I read that my modular plug-ins are CPU hungry, it's not really true. I compared the CPU use of the KX-SYNTH-X16 with other modular VST plug-ins, its CPU use is similar and pretty usable. The last demos have been created with C5 Essential on Vista. Actually I use a Quad Core 6600 (2.4 ghz) with many instances of KX77FREE modular plug-ins, see my demos on Youtube.

Some of KX77FREE's plug-ins have been conceived few years ago (< 2007, 8x8cc, KXPM25) and they were not really  optimized than the KX-SYNTH-X16 or the new version of the Kx-Modulad. These plug-ins have many parameters and modulations, they can use a lot of processor resources if you use their 8 voices version.

Values
You can regulate small values with the mouse while pressing on the Ctrl key and also adjust some parameters with a numerical value in the field on the bottom of the knob, for example if one slider permits you to regulate a modulation up to a value of 10, you can however put this one at 20.
The values are in volt, e.g. 1 volt to an oscillator = a modulation of an octave.
Caution: If you fill the slider field with a value of 1000, you create a modulation of 1000 volts! 
It's a joke because the majority of the values are limited but... Read the paragraph "1-Warning " of the lisence.

0.000 = 0 % CPU
In general, if you regulate a parameter at 0.000, you put its modulation at zero, this one will not use any more resource. Each voice is off after the end of the VCA release, so avoid to use a long release time to the VCA.

Soundfont player module (plug-ins using the 1.0 SE SF2 module)
If you use several SF2 banks with a plug-in whish uses a Soundfont player module (KXSF2-ST, KXPM23, KXPM25, Kx-Step, etc...), it is important to load your sf2 file in each preset of your plug-in.
If you don't do this, when you will change the preset, the sf2 file loaded in memory will be the sf2 file of the preceding preset.

e.g.
preset n°1 = guitar.sf2
preset n°2 = (no sf2 in memory)
preset n°3 = brass.sf2
If in the preset n°2 you have not loaded a sf2 file, when you change the preset n°3 to the preset n°2, the sf2 bank loaded in the Soundfont player will be the sf2 bank of the preset n°3: brass.sf2.

preset n°1 = guitar.sf2
preset n°2 = piano.sf2
preset n°3 = brass.sf2
If in the preset n°2 you have loaded the piano.sf2 file, when you change the preset n°3 to the preset n°2, the sf2 bank loaded in the Soundfont player will be the piano.sf2 file.

This module manages the memory dynamically, you can load the same Soundfont in several presets from the plug-in. This problem does not exist if you use only one sf2 bank for all of your presets.

If you click with the right button of the mouse on the "load" text, you can unload the bank sf2 from the memory, that will take effect immediately only if you turn off your plugin and you activate it again (Cubase Se).
--> button on top and on the left of the window of the vst plug-in.

Percu plug-in
To change the page of the instrument (from 1 to 11), you have just to click on the number above the keyboard with leds. This one has 5 stereo outputs to apply a different FX to each percussion instrument (11 layers). Each layer is adjustable on the keyboard.
Known Bugs: the sample player does not accept the 24 bits files, if you load this files Cubase crashes...

About my old plug-ins:
I did not incorporate any FX in these plug-ins. I preferred to create my FX plug-in, KXDELAY2, to optimize the mix.

Description of the KXMOD system (1.0 version, written in 2005, KXPM)

Sm-KXPM25 SCREENSHOT (ENGLISH HELP, 0.7 Mo)

1 The parameter "*Hz" creates a very slow cyclic modulation to the voltage of the oscillators, reproducing thus an instability of the power supply.

2 The parameter "Kbd tune" reproduces a bad adjustment of the keyboard, the tune is not linear according to the position of the note (A2=0, A3=0, A4=0).

3 The parameter "RND" reproduces the equivalent of characteristic defects of the polyphonic vintage keyboards: the polyphony is obtained with several independent monophonic synthesizers.
Each note starts one monophonic synthesizer which inevitably has an adjustment slightly different from the others.
You have the choice between two adjustments: "RND" or "Voice", "RND" is a random value while "Voice" is a fixed value.
The output of the noise generator which creates the random values can modulate the principal modules : vco, vcf, vca.

4 The parameter "Kbd" allows an adjustment of the oscillator level according to the note played on the keyboard (A3=0).

5 The Vcf has two filters, because the digital filters are less effective than their analog equivalent. The musician has the impression to use only one filter because the second filter is controlled by the same cutoff adjustment than the first filter. The cutoff of the filter 2 is slave of the filter 1. It has an offset to obtain a variation of the filtering slope. The filters can be used in series or in parallel.

6 The Cutoff modulation made by the envelope generator can be not linear (Linear, Exp, Exp-inv, dB, dB old), to createa filtering with more or less punch.

7 The Attack parameter and the Release parameter of the envelope generators can be controlled by the velocity.

8 Each envelope generator (also the lfo) has a synchronization clock which can be independent from the tempo of the vst host software. The clocks are adjustable with an offset (more or less 240 Bpm).

28/11/2008 (V 1.04)
It was unusual for me to work on VA but when Burnie asked us Nova and me to do a VCS3 plug-in, I was interested. This old EMS synthesizer is great with its modern matrix concept, its joystick and its possibility to do feedback patches. Nova collected some docs and Scot Solida sent to Nova his recordings. I used them to research the way to do a close oscillator simulation. I did a new filter based on the KX filter code. Nova built a modern skin. We did not built another SE clone of this synthesizer but added some great features on the original concept.

01/06/2009 (V 2.00)
One of the new features of the 2.0 version is the polyphony with a total respect of the original feeling of this synthesizer. A new KXMOD system is implemented to create fat vintage leads or nice polyphonic instruments. A CV and gate sequencer has been added to create real vintage sequences.

20/02/2010 (V 2.5)
This new version was designed for live sessions. The full Midi learn was added. The stability improved and tested in all major hosts.
Now, they are 3 versions:
KX-SYNTH-X16-V25, main polyphonic version, zip file or setup.exe are available.
KX-SYNTH-X16-M, monophonic version which replaces the old 1.04.
KX-SYNTH-X16-FX, VSTe version for use the audio inputs.

03/07/2010 (V 3.0)
The KX77FREE oscillators replace the native SE oscillators (tweaked with a lot of modules).
The result is -40% of CPU use won (-33% up to -50%).
The waveforms have been modeled by using additive synthesis (Wavetracer v2.0).
This technology produces waveforms like the original analog waveforms, the timbre and the shape can be identical or very close.
Now, the Kx-Synth-x16 oscillators are 100% compatible with the Kx-Modulad waveforms. These waveforms are available on http://kx77free.free.fr. The file is  "x16-Add-Waveforms.zip".

11/11/2011 (V 4.0)
New version of the built-in sequencer, now it is polyphonic with 6 tracks available.
Various improvements have been done.

Common features with the VCS3
Three variable shape oscillators.
16*16 pin matrix with feedback connections.
LP filter, 18 db per octave with self oscillating.
Noise generator with EQ.
Ring modulation.
Two external inputs (only available with the FX version).
XY joystick.

Added features

KXOMNI-600
Analog and phase distortion stereo synthesizer with KXMOD system.

Each Layer is composed of two oscillators: a "Phase Distortion Oscillator" (Pdo) and a classic oscillator. The oscillators signal can be filtered by a multimode filter, a distortion shaper and modulated by its own feed back signal. All the modulations are controlled by an envelope generator, the velocity and the keyboard. Then the layers sound (4 oscillators + 2 filters...) is filtered by a stereo VCF and finally amplified by a stereo VCA. All the modulations of the oscillators can be modulated by a double LFO.

New Moog filter, new fx with 2 delays and a distortion (same modules of the Kx-Modulad).
New ADSR and implementation of the KxStep EQ.
This plug-in has also a SoundFont player.

A search began in 2002 around the structure of the "Mini", this version takes advantage of several modules of the Kx-Modulad and its original Kxmod system. The new bank includes over 70 presets.
This plug-in is technically more advanced than the older versions of the series KXPM that's why these are no longer available, only the SM-KXPM25  is available because it has a different structure.

Musics created with the KX77FREE plugins
Mir and Casta are extracted from LiveInMyHome album. The work on the sound and the mixing are improvised during the recording of the piece (KXPM). The locators of the midi sequencer are modified during the reading of the piece (Casta 2004). Background is not improvised, but it is entirely realized with KX77FREE plug-ins: KXPM, 8X8CC, PERCU and KXDELAY2 (except the reverberation: M 300).

The experts will notice the influence of Klaus Schulze. It is true: it is listening to his music that I began to feel like playing electronic music...

New versions of Casta (07-2005)
Improvisations played the same day starting from the Casta piece.

Musics created only for the KX77FREE plugins demos (2005)

The sounds of the demos vary according to my inspiration and are not always included in the soundbanks delivered with my plugins. Some demonstrations were created using midi files (J. S. Bach's scores).
