I'm hoping someone may be able to point out whatever obvious step I've missed in getting the Chocolate to control a couple of Zoom MS pedals (either an MS-60B or an MS-70CDR) via an MS-1. I'm trying to get Program Change A working with them. I have paired the Chocolate with my Android phone and set it to Program Change A, paired the MS-1 with the phone and set it to OTG, connected the MS-1 to the Zoom pedal (this is also the power for the Zoom pedal), switched Bluetooth off on the phone, switched the Chocolate on (flashing blue light) and then the MS-1 (flashing blue light turns solid, as does the light on the Chocolate) so I'm satisfied that they have paired with each other and not the TV or some other random Bluetooth device. I then try pressing switches on the Chocolate and nothing happens.
This setup is the same as that shown in one of the other videos by the same guy that did the tutorial about that @Smanth has included, except that I'm not using a separate 9V supply. There's another Youtube video that shows the Chocolate being used with an MS-50G with no 9V supply or batteries, so it should work.
One thing I'm not sure about - in Cubesuite, when I tapped on the right-hand button with what appears to be an expression pedal on it, I see [1] 1 CC 0 0~0. If I press + to add another entry, I get [2] 1 CC 0 0~0. I'm not sure if this is simply a CC for the expression pedal (which I'm not using) with the first parameter being the control it applies to and the 0~0 being the range. If so, that's all irrelevant to me as I'm not using the expression pedal.
Is there anything obvious (or not obvious) that I may have missed?
