Not the op but note Korgs latest 1000$ digital synths are all powered by raspberry Pi. Most other digital synth manufacturers too use off the shelf chips like SHARC etc. There's neither shame nor is it rare for established manfucaturer to use available stuff and not reinvent the wheel. The world market for these devices is smaller than we normally assume and second hand market is huge. There isn't as much money in synth hardware as one might think.
