  1. 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.

  2. Correct. However, my point was that I was using three ports instead of two (what most of the current doubler cables are doing) to give more thermal headroom to each of the regulators (~300mA instead of ~450mA per LM317 if you assume 900mA current draw from the Helix). Of course the overall power dissipation will be the same. The decision to do the wiring internally was more based on aesthetics and practicality.
