Hi Lugia,
thank you very much for your effort to give advice on my expansion plans. I appreciate your experience and know-how - awesome!!
Due to space economical reasons in my project studio I don't use a mixer. I hooked up my non-modular synths and FX via balanced patchbays so I could run every synth through the FX/outboard gear I like and than to the audio/ADAT interface (everything in my studio is balanced cabled so I like to have a balanced master output for my modular system, too). Rosie's TRS output ist linked via one of the patchbays to a pair of channels of my audio interface. The system works stand alone (without PC) for jamming, too. Therefore I like the idea to have a small performance mixer in the modular rack helping me quickly dial in loudness, muting and panning when I am jamming electronic and technoid stuff (those basic functions have to be CV controlled for the more ambient and generative tracks on-top of manually mixing). Because of that secnario the Xaoc Praga has been in my mind for a while.
The idea of phase shifting the Telharmonic sounds promising, thanks for that (I have a Vermona analog phaser PH-16 in my 19" rack, so maybe I can utilize this or of cause the super-duper Xaoc Kamienic - but no rack space for this). Concerning the filter there are so many good alternatives, but as you said cause of rack space in combination with what I have and planning to achieve the Xaoc Belgrad should be a super option. Beside its special sound (could be used as a more classy liquid filter, too) I love the Xaoc look & feel and the overall outstanding build quality of their modules. I will put that filter definitely into the rack, I have ordered one today at Schneidersladen in Berlin (coming in at April/May as a new batch of Xaoc Devices is on build hopefully - yeah).
I like your suggestion with the Delphtronics LDB-2 (didn't know the module until yet). Because of the limited size of my modular system I thought a lot about putting dedicated drum modules in it or going with a external drum machine instead. So I think it is a good idea to keep the drums on the small side here and utilize my Elektron Analog Rytm more often besides the modular. To keep things more simple I like the idea to do some basic drum works within the modular via Pico Drums, Tiptop One or sometimes Peaks or Braids and for more crazy stuff Basimilus Iteritas Alter (utilizing the latter for basslines and technoid building blocks instead of percs, too).
One of my main questions still is, how many envelopes will I need. I have a classic envelope on the SV-1. It could need a second ADSR for separate filter and VCA modulation. The Telharmonic needs sometimes an ADSR envelope, too (not only vactrol kind of VCAF filtering like with the Optomix). With Peaks I have two independent envelopes in different style, the Disting could deliver, too (will sell the MK3 though, replacing it with the MK4 - much better user experience with that new small digit display). To ensure another swiss knife function a second Disting could be nuts. Maybe I leave it for a while as is and see what I need in upcoming patching situations. Hm...
As I speek "Optomix" - as I like to keep the Tallin (cause i bought it recently and it sounds amazing as an VCA for audio) - should I plan with the Optomix or should I better drop it for something else? I guess I need a good sounding lowpass gate in my system, maybe using the Make Noise LxD instead of the Optomix and fill up the remaining space with one more envelope generator?
Last but not least thank you very much for your arrangement tips, Lugia. That is what I am struggling with sometimes, luckily with this rack of a manageable size it will somehow work together. Nevertheless I will follow your structure from left to right and bundling functions.
After considering your suggestions in sum I have put the rack like this - of cause not a final building plan. Any more suggestions or comments on that are highly welcome!! :-)
