Hi all, I just got a Boss SY-200, and was really happy, because you can select patches and control various parameters via MIDI. HOWEVER - after messing around with menus all day, and still not finding a solution, and using the process of elimination, I found that it was either the MIDI 5-pin DIN to 3.5mm TRS cable I purchased, or it was the Boss SY-200 itself. After some research, I began to realize it was that the cable was configured incorrectly - that the tip, ring, and sleeve of the TRS plug were not connected to the correct pins on the 5-pin DIN (MIDI) plug. So, I cut one of mine open, and switched the wires for pins 4 and 5 and everything is working great now. So, if you are trying to connect the new Boss SY-200 to your Helix, and the program changes do not transmit, this is probably why. I tried with two different cables, and neither worked until I modified one, which then worked. I sincerely hope this saved some folks a lot of time trying to track this problem down. I have attached a pin diagram below. PS: PLEASE NOTE that the Boss SY-200 DOES NOT output note-on and note-off data via MIDI. In other words, you can't use it to control a MIDI keyboard or tone module, like the Roland GR-30, GR-33, or the GR-55. The Boss SY-200 is NOT that kind of guitar synth.
