Le post sur Kvr est ici:
J'ai écris un petit texte d'aide en anglais :
A little help to begin with this synth:
I tried to simplify the modular part of this synth to avoid multi-panel GUI.
Even if there are a lot of knobs on the panel, this synth is easy to understand and very classic.
On the left, there are the signal generators:
Vcos, Soundfont oscillator(Sfo), Ring Modulator, Noise, Lfo, SH, Kxmod
and on the right the modifiers:
Vcfs, Vca, etc...
Mono generators: Lfo, Noise
Poly synth: Vcos->Mixer->St Vcf->St Vca
3 waveforms (*.kxw) are embedded in this plugin: Sine, Saw (Pw, TriSaw),
These waveforms are very close of the Prophet 600 waveforms!
You can add KX77FREE waveforms in the plugin folder, only the Med quality
files are compatible (med, 498 ko).
The KX77FREE's voltage controlled oscillators use look up tables made with the KxWaveTracer of the Kx-Modulad.
1 volt per octave (1 note=1/12). 1600 harmonics for 13.75hz (0 volt)!
Use the tree selectors (Sine, Saw, Tri) to change the waveforms if you added waveforms inside the plug-in folder.
The Pw uses a Saw waveform: Saw-(Saw with its phase*Pw).
So when you change the Saw waveform you modifies the Pw waveform!
TriSaw is different of the Pw, the Tri is mixed with the Saw but the Saw phase follows the mix.
This is a special feature to reproduce a similar waveform of the Mini Moog's TriSaw. The Pwm values (matrix and knob) modify the TriSaw.
The dual-oscillators have the same pitch of the oscillators but you can
It is the same for the Sfo pitch which follows the Vco3 pitch,
it can be transposed.
You can reset the oscillators phase to 0 with fade or not (note on).
Free: no phase reset
Gate: reset with no fade (0 ms)
This is not recommended with Mono or Soft Poly with long release time.
Gate S: reset with Short fade (5ms)
Gate M: reset with Medium fade (10ms)
Gate L: reset with Long fade (15ms)
The vco1 can be hard synchronized by the Vco2.
You can reduce the digital artefacts on the high frequencies with the HF fade selector.
The dual filter is cool to do a lot of variety of filters , after you adjusted the F2 offset and the mix between the two filters, you can use them like a classic vcf with only one cut-off.
The filters with * are oversampled.
15 sources to 12 destinations:
Pitch (Vco1,2,3), Pulse Width (Vco1,2,3),Phase (Vco1,2,3), Master Cut off (Vcfs), Pan and Vol (Vca).
Click on the source names to adjust the modulation levels with the mini knobs.
The Sfo uses the same pitch than the vco3.
The mini knob on the left of each source is the amount of control by the Sub Matrix...
With the Sub matrix you can control the matrix modulations, the vco levels with the Midi controllers, the Egs, etc...
There are 5 source selectors, 3 monophonic and 2 polyphonic.
Click on the source names to choice the sources.
The type sources are separated because when a poly signal modulates a mono signal, this one becomes polyphonic:
Eg1(poly)->Lfo(mono) = Eg1*Lfo(poly)
The SE engine is limited by the fact that the internal connections are fixed
in the VST, that why the poly modulations must be separated of the mono
modulations to control the CPU use!
This plug-in is optimized but if you patch with a wrong way you will increase
the CPU use!
First, do the difference between the source signals.
The polyphonic signals use more CPU, one modulation per note played.
Do not select a source if you don't use it with the matrix, select off or None on the selectors (sub matrix, ring, filters).
Avoid to use oversampled filters* or select NoRes if you do not need resonance.
Set the level of the unused generators to 0 (led off).
Monophonic: Lfo, Noise, Lfo Eg, SH, Midi Ctrls.
Polyphonic gate on (note on): Kbd, Vel, Kxmod (1, 2, 3).
Polyphonic alway running : Kxmod*, Vcos, Sfo, Ring Modulator, Egs 1 and 2 (to release end).
This is a feature which is regularly implemented inside the KX77FREE plug-ins since the KXPM22 (built in 2003, provided in 2005)...
Kxmod 1,2,3 are fixed detune values for each voices (or randomized).
The Kxmod* is the same but the values change slowly like a variation of voltage.
