Carla on Raspberry Pi Small Touch Screen

[RK11111111111]

I have a project. The ultimate goal is to have a device that boots directly to a synth, so that kids can use it. No poking around on the desktop. Turn it on, wait play, then play the synth with a midi keyboard. The OS I am using it Raspberry Pi based. I have built similar devices based on Raspberry Pis before. A headless minidexed. Which doesn't use an OS at all and Mixxx a DJ controller software.

I have built a Raspberry pi, however when I launch Carla, it is completely off the touchscreen. I can use mouse and keyboard to navigate, but eventually I don't want to use these. EG right click won't work.

I have gotten Surge to work with Carla! The window is just a little large, but not bad. Any ideas on how to get the device to load jackd, carla, and start with surge open?

I was thinking about maybe forking the Mixxx, repo as it appears to have done something similar booting a Raspberry pi desktop and setting up all the audio configurations, then loading Mixxx.
