Very happy new Zynthian user here - and after a few weeks with my official Zynthian V4 device I’ve decided to add another Zynthian rig to my studio, based around the Audiophonics SABRE DAC. [1]
Trouble is, it doesn’t have knobs - but I do have 4 Griffin Powermates [2] sitting in a drawer, and I’ve used them with rPi projects in the past … so I’m wondering, if any of you guys who know more about Zynthian have the time to think about it - how much work would it be to add Powermate support for Zynthian?
As far as I know the Powermate emits HID events … I’ll have to wire these up to the Zynthian UI somewhere … can someone point me in the right direction?
Hi, as is I would Say that you will loose the 4 USB ports of the rpi. But maybe you plan to use a USB hub, …
Secondly, I think that this will not work out of the box and should maybe need some software developpement. But I could be wrong. Or not.
Lastly, wiring 4 encoders on some cheap mcp23017 port expander like this one isn’t that difficult. And you will be sure this is a working and “officially” solution. Schema is here
Yes this could be pretty nice: for connecting USB midi stuff like control surface, midi keyboards and so on especially when these Gears are USB powered only (… if that hub has a third party power supply, but it should be the case from what I’ve understanded so far).
But questiin remains : will these Big USB knobs work as is with zynthian ? I’m not sure at all without some software hacks.
I can’t see an easy way to make these cool and expensive knobs work with Zynthian without changes to code that I feel would not provide substantial benefit. You may be able to obtain / write some glue that converts the USB signals to something Zynthain understands, e.g. MIDI.
