If you can find a local store that has one, try it in the store with a laptop. If there is a profesional audio equipment rental place, you may be able to rent one for a day or two for not too much money. I try to always buy where I can at least return not working things, but at least I can try it out in the store. Dragging a pi to the store may not be so easy or inspire confidence in the sales people that it will not damage their thing(s) you want to try out. ;) The R-pi has only one USB port which it shares via an internal hub with ethernet. If you are not using ethernet and your control of the system is via GPIO pins, so that the only thing using USB is the audio IF you may have stability. I do know there are some tricks to follow for doing audio on the PI in general. The PI3 does not seem to be any improvemant over the PI2 in terms of USB... at least the features seems to indicate the USB on the 3 is the same as on the 2. See: http://wiki.linuxaudio.org/wiki/raspberrypi It is written by someone who has actually used USB devices on a PI :) They use the ethernet ok... so for controlling you may wish to try one of those numeric-pad only keyboards made to extend the laptop keyboard. Check your local goodwill store for used keyboards in the 3$ range. A 5inch touchscreen is another possibility. -- Len Ovens www.ovenwerks.net
