I flashed the iso to a 16gb sd card using etcher and then enter root/root on login. Then when i try to follow the install instructions which say to run sudo apt-get update, i get --bash: sudo: command not found. Im new to this stuff and havent been able to find a solution anywhere
You are root already so no need for sudo.
And as samplerbox is a (stripped) single user system (making sudo not needed) it's not even installed.
Also apt-get update is usually not needed on the samplerbox image.
What kind of install instructions are you following?
I realize now that i was trying to follow the manual install instructions which i probably dont need since i have samplerbox flashed to my sd card already :P
Still it doesnt seem to be starting up correctly. Im just loading into a command prompt asking me to enter my root/root login and then nothing after that. Ive tried to plug my Midi keyboard in and play some keys but nothing happened there. Is there any further set up i need to go thru or should i be able to play right after boot?
The image you flashed onto the SDcard automatically starts up the sampler box program. However you can't see it running, because it is running in background.
To see what's happening, you need to stop the sampler box program and then start it again by giving a command. Then it will display all kinds of debugging info detailing what it is doing. That will help you to see what might be wrong.
The actual program is at /root/SamplerBox/samplerbox.py
Here's how to kill off the running SamplerBox program and manually restart it:
sudo killall python
