I got a Yamaha BC2 Breath Controller on Ebay to use with my SY99. Does anybody know how it works? I know It plugs into the keyboard and I guess you blow into it somehow while playing the keyboard. I hope it comes with instructions.

Just picked up a BC2 myself. It came with a single page for instructions, which will show you where to blow and where the drain plug is. If your page is missing I can scan and send it to you.

Remember that Breath Controller response needs to be active in a program in order for there to be any effect. Check each patch you have for 'BC bias' or 'BC sensitivity'. Have fun.mn

I got my BC2 in with the instructions so everything is A-OK.
