Top Lugia, thank's alot - I will free some space for the envelopes. Because I am a sound designing nerd I have to keep the O'tools oscilloscope.
Option A: If I drop the Synthrotek ADSR and one Disting the 8hp could be filled with four envelope generators by 2hp (2x AD/AR module and 2x ADSR module). The rack would look like this:
Option B: If I drop the WMD MSCL and the Ladik Output module for the suggested Pico Out, and furthermore dropping the Pico Logic, Synthrotek ADSR and Optomix (LxD instead as my low pass gate) that together would free up space for...
...the very new Mutable Instruments Stages - should be a super flexible envelope generator with one huge six step envelope or for example DADSR, AD and ADSR, 2x ASR, 3x AR or AD etc. Alternatively the Stages LFO function could be dialed in. Envelope curves can be shaped and time/level CV manipulated. I think that could help me out with my envelope problem in this rack (Peaks could be dedicated to the Praga in expert mode with 2x ADSR). The Stages just shows up the right time... yeah! The last 2hp could be filled with the Pluck to have some Karplus-Strong sounds (no Rings or Plaits on board).
So the rest of my rack will be developed like this (still not sure about final arrangement of the modules - so I configured two arrangement options). What do you finally think?
