these things are all a matter of what you want to do exactlyā¦
if you just need rings, then you donāt really need to use Orac , which is more aimed at combining things - you could just use my PD wrapper/patch for rings - but youāll need to do midi mapping etc if you want thatā¦ but that doesnāt take that long in PD.
(or yes, you coudl just use axoloti which I also put rings on.)
rPI w/ pisound is more powerful than bela, both cpu and fpu.
(but a single rings is not going to require much cpu) - but IO is not as easy as bela, but perhaps MIDI is enough?
belaās advantage is its got (8) analog inputs for your pots, so thats easy, just a small tweak to the rings patch and your done. its also much lower latency than rPI based solutions. bela doesnt have midi din, but you can add it simply enough, or use USB din cables.
axoloti, if it does what you want, is cheap and is instant on (unlike bela/rpi solutions which take a few seconds to boot), its like bela very low latency - but its less powerful, but its completely dedicated to the task - so its surprising how much it can do!
(axoloti does not run PD, it uses its own patcher, which is āsimilarā )
if you want something general purpose, and might need more cpu, then rPI is probably best (but you need to think about IO for pots)
if you really want to build a custom instrument, so need more io, and want lowest latency , then I tend to go more towards Bela/Axoloti - they are both really designed for this.
(bare in mind this is all comparitive, any of the above would probably be fine!)
