Is it possible to try out zynthian with just a raspberry pi (and a hifi hat)?

@lastebill

Are there any images that are capable of running on the pi 4 yet?

Absolutely! All “Buster” images can run on the Pi 4. I use Buster RC1, available in the Zynthian Wiki.

Secondly, can you split the midi keyboard, so that you play base guitar with your left hand and say piano with your right hand with Zynthian?

I think people are working on that. Try this topic:

Midi Filter Rules: Keyboard Split + Single Channel Mode

I´ve tried to make a keysplit with my raspi 3. But in single channel mode with split 45 or 59 I hear by sending ch1 or ch2 the sound 1 or sound 2 but not both dividet by splitpoint. [12] [13] sry, don´t have an ui log

@lastebill

Thirdly, can you (prefearably easily) set knobs and sliders on a midi keyboard to do stuff, like increase and decrease volum, add and remove effects, etc?

This Wiki article explains setting knobs and sliders to do stuff, and this Wiki article explains adding/removing effects.

Hope that helps!
