Thread: Rack for live sound manipulation (long samples, field recordings) + inevitable minimal rhythms
That seems like a matter of taste to me. I've sort of avoided the Frap Tools stuff because of their oddball user interface choices, though they are doubtlessly very powerful instruments. Cs-L looks like a great choice. I like my Furthrrr Generator, but it's 30hp, so takes up more space than the Cs-L. I stumbled across a complex oscillator blind shootout somewhere, and preferred the sound of the Furthrrr and surprisingly Make Noise's DPO. Maybe see if you can do some head to head comparisons.
Let us know what you decide.
