It would be nice sometimes not to have to bring a laptop onstage, and I'd like to
know I'd like to know if I could run Pianoteq on a BELA board https://bela.io/products/
Its a 32-bit ARM processor running Linux and has its own 16bit audio outputs
suitable for casual gigs. Anyone know if this would work?
I am not familiar with that system but from the link it looks like it uses a board (Beaglebone Black) with an ARM running at 1 GHz. That's probably too slow for Pianoteq as the ARM systems normally used would be running at maybe 1.5 GHz or above. There are quite a lot of small form factor devices now that might be a better choice for running Pianoteq. Also keep in mind that while relatively common systems like the Raspberry Pis have relatively well developed and supported versions of Linux, you might find it harder going off the beaten track (unless you're pretty comfortable with Linux troubleshooting).
