I know it's highly unlikely (because the plug a long time), but maybe not in vain...

1) Please, add LFO and Step Gen in Mod Matrix as a source. 
2) Add the ability to generate basic waves (VA) to oscilators (But this is less important than the first point, but it would be very cool.)

  This will turn Rapтure into a self-sufficient processor, and very significantly increase capacity.. 

Good ideas.  I have no idea whether Rapt will get upgraded or Cake will produce another synth.  Rene who wrote Z3TA, DimPro and Rapt is gone, but Cake upgraded Z3Ta afterwards, so ...

AT, Clearly, thanks for the info.
