hi bubblefunk and thanks a lot for your answer.
there are so many possibilities available that it really is a journey, quite a nice one.
i've been considering several options since i wrote the post and i guess it really helps to write things down sometimes. by now i haven't quite think about connectivity with ableton, sequencing and modulation well enough. also, if you add polyphony is easy to see that i would need much more rack space available and that would turn my "make music anywhere" idea down. that's why i decided to start with this approach; i got me a volca kick and a volca sampler, so this will allow me to start experimenting with some drums and also use it as a sampler outside ableton. Also, i will try to use them as a clock for my system later, since i already saw some people doing it. although, i really don't know if i could use the volca sequencer to trigger the modular. i'll see with more time and calm. i guess this first approach will bring some useful insights to keep growing based on a solid idea. i also will try not to burn the cash and that's why i'm limiting myself from the start.
by the way, i could demo the oberheim ob6 and in my opinion it really sounds amazing. the poly korg you are referring too is the minilogue? i guess i could also try first with a second hand volca keys to get an idea if that's really the approach i'm looking for and then try to implement it into the modular if possible somehow.
also, thanks for your opinion on maths. it's nice to hear that you simply like more a different way to work. i'm not sure if it is a must for me, but i had the feeling that i was getting two modules on one, since it has two channels and can work as an attack decay envelope and also as an lfo. i'll do some more research on it and decide.
i also want to thank you for suggesting the new pamela. i know nothing about it, so i'll also do some research on that against batumi and quad clock.
thanks again for your input
