Control a filter cutoff with the velocity

You can use the Modifier MIDI plugin for that - no need for any modulation setup on the synth itself. All it needs is that the parameters are learnable.

Insert the Modifier plugin (it's a MIDI plugin - dedicated slot above the instrument), set the Reassign To field to Learn Plug-In Parameter, next wiggle the cutoff knob on the instrument, and there you go.

This is not really a good way to go here - it'll work ok for a mono synth, but will be horrible on a poly synth where the most recent note velocity will globally control the filter parameter on the plugin, whereas when you set this up on a synth it will probably be a voice parameter and control the filter for that note only.

Hmmm... but what velocity will a poly synth with modulation routing use? It'll probably not apply different velocities to each note of a chord either, unless it has a separate filter per voice - and which synth has that?

 

Um, *all* true polysynths have a complete synth (osc -> filter -> amp etc) per voice.

 

It's only paraphonic synths that have a shared filter for multiple voices.

 

Every voice in a polysynth is voiced independently, because it has a complete synthesiser for each voice (this is also why analog poly synths were expensive - an 8-note polysynth had to have 8 complete synthesizers in there (plus some global stuff).

The affordable synths like the Korg Poly 800 were indeed paraphonic - one filter, but 8 voices. That's why they were cheap (and crap ;) ).

 

Actually, there weren't that many paraphonics (because they were less useful and a poor substitute for a proper polyphony). It was more common for budget polysynths to just have one osc per voice instead of two and make the voice path simpler, but still have a proper complete synth engine (osc -> filter -> amp) per voice.

 

With digital of course, you no longer need to worry about the cost of components (or the heat when you jam them all into a metal case), so you can have 128-note polyphony, without the only cost being the CPU required to use them, but again, you can implement digital filters in many ways from cheap (low CPU, but not very good sounding) to expensive (high CPU, but very good sounding filters) - and often, the user gets to choose which filter models to use...
