First let me apologize if these are stupid questions.
I don't quite get how to launch an effect. If I understand correctly, I just execute the program (i.e. effect) on the pi w then plug in my guitar and have at it. Is that correct?
However, if I need to disable wifi to reduce noise then I obviously will be unable to access it once I disable wifi. If so then in order to stop/change the effect I have to plug in a keyboard/mouse/monitor. If that's the case then the pedal-pi must always be plugged in. Is that correct?
Any directions from turn on the pi-pedal to plug in the guitar to play guitar badly with cool effects is greatly appreciated.
In headless mode, once you disable the wifi, you cannot access remotely the pi zero, so you cannot change the effect. But that is not a big issue, if you want to change the effect or access the pi zero, just unplug and plug it again (to the power) and it boots in seconds...
