I got an (old) B-Control Nano BCN 44 and was trying to use it to complement my Yamaha PSR310 keyboard with pitch/bend and modulation. I found out that when i use the device to directly control cakewalk sonar while playing back a track, everything works fine and the notes are being pitched. If i try to use the "Midi-Merge" functionality (keyboard midi-out -> bcn44 midi-in, bcn44 midi-out -> soundcard midi-in) then i got a strange problem with latency. When i press a key on the keyboard, the keypressed signal is being send via the bcn44 to the soundcard and the note is being played. But if i shortly after pressing the key, i release it then the keyreleased signal won't be sent to the soundcard (so the note keeps on playing). Same in inverted order. If i press other keys there always has to be a delay time of approx 1-2 seconds in between. Otherwise the corresponding notes would'nt be played. It seems as if there has to be always a delay time of 1-2 seconds in between midi-signals sent from the keyboard to the BCN44. I wonder if this is an issue with firmware on the BCN44. without the BCN44 in between the keyboard and the soundcard i got no problems at all. What could be the reason for this?
