Other specific ways to setup hardware control for Pigments ?
Here are a couple of videos michaeljk1963, to show a general approach to this.
There is this rather old video ( before HS as a MPE controller ) with Flux using a Hydrasynth Keyboard with Pigments.
Specifically he shows setting up controls from the eight Macro control knobs ( with text labels ) using the Mod-Matrix with internal HS modulations, using the ribbon, and polyphonic aftertouch.
I know you only have a HS desktop so can’t do everything shown here but you could do a good part of this.
This procedure applies to the whole method of setting up any MIDI controller as a controller for a specific software package.
Pigments has MPE, so you could go back to the MPE controller list for an extra level of control from that sort of controller.
As for instance Sensel has put a free package together for using their Morph specifically with Pigments. They did a couple of videos about this, here’s one.
Again the same sort of principles applies to whatever sort of MPE controller you decide to use.
Whether this all takes things far enough is another question. ( Do i sound doubtful? ) Hope this is even a little helpful.
ADDED : I just recalled michaeljk1963, you own a Linnstrument. There are several YT videos of people playing the Linnstrument with Pigments. Didn’t find any tutorial videos about that though. So then you’ll only need to combine your LS with other pure controllers, as CCMP suggests, to get thst hardware control.
