GP5 Volume Pedal Support

[photogphred]

First off, love this project. Good job.

Secondly, as great as the whole thing is I really only need a very tiny portion of it. I want to use a volume/expression pedal to control patch volume (CC#7) on the GP5 wirelessly. I don't need the UI. I don't need all the other niceties. I just want to send volume info from my pedal to the GP5.

One thing I'm trying is to use an esp32-s3 connected to my pedal to send BT-MIDI to a CME WIDI UHOST which is plugged into the GP5. Not sure if this is going to work, but it's my fall back if I can't do it directly. Obviously it's no fun having another device hooked up the the GP5. This is why your project intrigued me.

Is this possible with your project? If so, is there a pared down version I could use to just implement the volume pedal?

Hi.
In terms of a paired down version, the closest thing would be something like the Waveshare Zero board, which is small and cheap and doesn't use an LCD display.

Expression pedals are not supported right now but I have had quite a lot of requests for it, so I do plan to do it soon. I have some parts ordered to help me develop.

Sorry, maybe I wasn't being clear. When I said pared down version, I meant just the software portion. Didn't know if there was a base version that just did all the communicating stuff without the UI, etc.

Being an embedded system, its all tied together. When a device like the Waveshare Zero is selected, there are build defines that remove/change some sections, like removing display support.
It's all one code base though.

Sounds good. Any ETA on volume control?

The expression pedal I ordered is coming late January. I would guess beta testing of the next version with support would be mid-February.
