new superdough features

[felixroos]

let's use this issue to collect ideas for new features of superdough, the synth / sampler / effects engine..

feel free to add any ideas here and I'll add them to the list

Here are some more:

• [x] Envelopes on fmh and fmi for more dynamic synthesis.
• [x] Envelopes on filter cutoffs and variable parameters.
• [ ] Basic Karplus Strong algorithm exposed as an oscillator.
• [x] Simple Wavetable synthesis with a set selection of waves. https://github.com/tidalcycles/strudel/pull/698
• [ ] Inject dynamic Faust code using AudioWorklets (see https://www.npmjs.com/package/@grame/faustwasm)
• [ ] Using multiple waveforms on a single synth:
  • [ ] à la Moog: saw|triangle|sine.
  • [ ] Manual oscillator tuning/detuning (cent, etc...).
• [ ] Access to the woscillators
• [x] More simple basic effects (chorus, phaser, etc).
• [x] Filter Quality through a string (LP12, LP24) and unified set of parameters for tweaking the filter (cutoff, resonance, gain). Basic list of filter designs.
• [x] Noise Plethora inspired oscillator for percussion design (short envelopes, rich noise).

maybe this could be used, or at least some effects from here: https://github.com/Theodeus/tuna/tree/master

some interesting things can be found here (gpl2), including:

• custom adsr
• custom delay
• distortion
• sample and hold
• noise
• pulse wave with variable duty cycle
• slide / portamento
• custom Two-pole low-pass filter
• wavefolder

more interesting things can be found here (mit) (mirrored here), including:

• ramp osc
• diode filter
• a bunch of custom drum synthesis
• RingBuffer
• Pluck (Karplus Strong?)
• LP / LP2 / HP / BP
• feedback
• Moog Filter
• custom envelopes
• custom synths
• bit8 ?
• percussion synthesis

I would suggest to prioritize static and global effects for a next batch of improvements. Having chorus + phaser + flanger + wavefolder + more reverb options would be really useful. Adds a lot of audio modulation for a very cheap cost.
