I’m hoping for an eventual full-modular environment, similar to what is going to exist in Bitwig 3. Renoise is nearly there as it is. The only difference I’d like is that the oscillators remain sample-based. So, the sampler would remain at the head of the process, but additional synthesis parameters could be added to the structure.
So, you want FM / Additive / Wavetable / Granular, just pop on the piece(s) that are necessary. I’d imagine FM could exist as a mini-sampler - load your own, as well as the wavetable synthesizer. Additive and granular are different beasts, not so sure about them being sample-based in the same way. I did enjoy fiddling around with the granular synthesis in Bitwig’s sampler, though.
Coming from Reason, I’ve all but dropped that environment for working in. Renoise, for me, is speedier. I wanted an insanely digital sound, and this environment provides it in spades. I haven’t had any trouble making nearly any noise I’ve wanted to.
I do wish that we could have some of the synthesis stuff that’s in Reason’s “Europa” synth, natively. In particular, the FM synthesis and the ways you can modulate the operators. Even still, we have a hyper-speed, low CPU, abstract electronic production power-house of a DAW here. I can make full-on boom-boom music here, all the way to glitchy, ambient heaven. I am a happy camper.
