KX77FREE has released KXOMNI-600 v2.0, a freeware synth made with SynthEdit extended with Xavier’s own sem modules written in C++.

New in version 2.0

  • filter KX LPF
    • adjust resonance freely
    • noise modulation support
    • adjustment of the cut-off frequency is more precise (5v=440hz, 6v=880hz)
    • 4 new modes: HQ, HQS, HQM, HP
  • SE filter was removed and replaced by a bypass, if you do not want to use the filter that saves CPU
  • new curves of the envelope generators of Vcf and the oscillators
    The curves have a mode L which is a compression of the envelope generator signal, the Eg level is reached more quickly and it is maintained longer
  • mode L also exists for Vca (“comp” parameter)
  • oscillator waveshapers incorporates a bypass and the Exp-Inv++ curve was optimized (CPU saving)
  • oscillator filters have mode HQM and also a bypass (CPU saving)
  • replace vu-meters by an oscilloscope, analyzers of frequency, LEDs
  • distortion with an feedback adjustment and an ON/OFF(CPU saving) added the the fx section

good news for the kxomni users, I include in the Kxomni-U3.zip file the NFX version.

I build the NFX version for the users who use external Fx or prefer to use other Fx that ones of the kxomni.
example, with 4 kxomni use in same time, you win 10% cpu use on a P4 3ghz !
Also the program change cpu use is better.

version 2.02:
the offset of the lfo2 is usable simultaneously with the synchro.
