i’ll check out the forums if the price drops a bit, as it stands i think i can get by when i need to with the raspberry pi as a usb class compliant midi hub where controller x can connect to device y & z e.g (particularly with the new pi which has more usb ports) - pi may not be ideal, haven’t thought hard about latency, but it didn’t seem an issue, good thing is it’s flexible, cheap and small - i have little interest in iPad as an audio source, so i won’t miss that aspect, i just can’t engage with it on that level - anyway, cheers for fbk
