Parameter expansion plan

[mkruselj]

• Oscillators: 14 more parameters (for whatever). Tabs will be required at some point I guess. :)
• Mixer: Currently has 25 parameters. Add osc 4-6 volume (3), osc 4-6 routing (3), osc 4-6 solo (3), osc 4-6 mute (3), all channels pan (9), ring mod source selectors (4), pre/post filter mixer toggle (non-param), post filter mix gain (1), repeat the mixer sans the routing buttons and ring mod source selectors for post mixer (25 parameters). Total 51 more parameters.
• FM Routing: Add lower triangle matrix (21 more parameters)
• Waveshaper/Voice insert FX: Currently has 2 parameters (waveshaper drive and type). Add support for 7 more parameters for each voice insert FX block (14 more parameters), making it 9 total parameters per block (8 knobs and a menu for subtype or a horizontal slider as additional continuous param)
• Filters: Add 4 more parameters per filter (8 more parameters).
• Effects: 12 more parameters (24 total per FX).

Further thoughts:

• Oscillators will need unison stereo spread parameter (Add different unison modes (detune and panning laws) #3150)
• Oscillators will need start phase parameter (Oscillator Phase control #867)
• Oscillators will need Character parameter (Separate Character parameter per oscillator, applied to all oscillator types #3338)
• Oscillators will need Drift parameter (Osc Drift - separate for each oscillator #4022)
• Mixer routing should be continuous between F1 and F2, instead of three position integer (Panning the oscillators between the filters #1150)
• Skin engine would need to be updated so that we can define panels containing parameters, so that we could create layouts for each individual oscillator type (i.e. reorder things so that Skew Horizontal is right next to Skew Vertical for WT oscillator, say). This would also be used by the effects, as well (Tabs/layout panels #1683)
• Waveshaper should get an extra parameter for DC offset (bias), HPF and output (makeup) gain (Even more waveshaper flex #4847)
• Waveshaper becomes a just one of several new voice-level insert effects, and we need to support Treemonster's parameter set which is 7 params (Promote waveshaper to voice insert FX block #6015)

I really like this document
14 per osc and 20 per fx seem a lot but otherwise spot on. My guess is moderation may walk us back from that a bit
I specially like using the skin engine for per oscillator type layout though too

And don’t forget that this will couple with knobs! Which is already an issue

[baconpaul]

But man with all those params you could make a pretty amazing spectral oscillator

[mkruselj]

Yeah my thinking is better expand the count so that we don't need to expand it urgently later, which would wreak havoc in automation list ordering for DAWs that don't do VST3 clumping (Reaper, Reason, Live...)

[baconpaul]

Yeah sure. Some number will feel right. The flip side is we don’t want to expose hundreds of ‘do nothing’ params to the DAW. But it’s a balance I’m sure we will get when we do it.

14 per osc

@baconpaul I meant 14 more per osc. So 21 total for osc. FM4 osc will need at least 14 if not more. :)
