it sounds to good to be true for me haha
i came across it on the bboah when i was looking into getting a midi message processor/channel splitter
was on the lookout for a Yamaha MEP4 till i found out about the quadra play.
the parts to build one are available and it would cost less than £20 to make one
was just curious about its performance, the .guide file hints that it may be quite processor hungry ..
