I think Helix is mature.
But to me only two things are missing.
1.The first is, that you can "draw" your own waveforms in the wave shaping mode, one of those four oscillator types Jonas creates (rompler, pulse width, shaping and string model).Maybe some help-utilities would be useful, something like drawing a sinuspart, a (coloured)noisepart or a flat part (sawtooth, square). Maybe something, that makes it easier to program(for Jonas) and more easy for the CPU.
2.The second thing is that it would be good to form a pressure wave. I mean a wave, that cannot form a tone (because the "frequency" is so low, that it's not a tone, in fact)but make a dry (and) soft punch. It doesn't go to zero, have no negative parts.
The thing, that I noticed is, that a click sound is pushing, when there is a short attack, but is getting limp otherwise. Maybe it's a problem that the envelope starts at zero, although you can adjust the wave beginning (phase) in helix or change the attack curve
I've been searching after a boom that's dry at the beginning and gets juicy afterwards. There are limiters and compressors that saturate your sound. I think the result Is more pressure- less tone ; I think that's something equal, but It cannot produce what isn't there (long attack 0x0=0).
I think an analog instrument produce tention when you press the key, that ends, when the key is loosed.
Indeed, a non-zero (constant) value as a "wave"-form, formed by the normal ADSRR2 envelope would be enough, but how to sample or how to produce it?
There should be no looping clicks or such things.
Maybe you can produce it in the drawing+shaping mode mentioned above.
A last thing that's not so important, is that you can draw such things like crackles from an old vinyl-disc You can "draw" it again but need more space of time. For the waveforms the mode should have a grid that show you the right waveform-length with the right pitch.
1. adding mouse scroll to be functional
2. drag-able envelopes (ADSR) so we can draw our own envelopes.
3. Double click to return to default value (this is very helpful)
4. Assignable macro controls ( maybe adding macro control tab next to FX tab)
5. Drag and drop mod matrix.
those will drastically improve the helix's ease of use. and save alot of time to explore new sounds.
