Hi, I bought a Roland HD-3 electronic drum and I would connect it to GB via Midi2usb cable, to use standard GB sounds.
After connection (midi out from HD-3 into iMac USB) I cannot hear sounds.
The cable is working because a midi keyboard to GB works perfectly, I can control sounds out of GB with my keyboard.
OSX Lion on iMac 21.5''
Sorry, it was only a matter of false contact of the cable.
Now communication is ok.
There is still a problem of catching all the beats that are played. -> See other post.
