Hello, I have a Roland RD 100 and I'm having a MIDI issue where notes sometimes hang.
I went though the test mode defined in the service manual (reference: http://www.synfo.nl/servicemanuals/Roland/RD-100_SERVICE_NOTES.pdf) and when I get to the MIDI portion, instead of 0 _ _ I get _ _ _.
When I connect the keyboard to a Midi Inspector (Snoize) I can see MIDI notes coming in, but the problem is that when I press two notes and lift at the same time, one of the notes doesn't turn off.
Pressing A5 works:
21:20:07.786 From Port 1 Note On 1 A5 65
21:20:08.130 From Port 1 Note Off 1 A5 64
Pressing B5 works:
21:20:09.059 From Port 1 Note On 1 B5 68
21:20:09.409 From Port 1 Note Off 1 B5 64
Pressing one then the other and lifting slowly works:
21:20:11.893 From Port 1 Note On 1 A5 50
21:20:12.696 From Port 1 Note On 1 B5 68
21:20:13.609 From Port 1 Note Off 1 A5 64
21:20:14.515 From Port 1 Note Off 1 B5 64
Pressing one then the other and lifting the other way slowly works:
21:20:15.551 From Port 1 Note On 1 A5 71
21:20:16.462 From Port 1 Note On 1 B5 71
21:20:17.410 From Port 1 Note Off 1 B5 64
21:20:18.350 From Port 1 Note Off 1 A5 64
Pressing both and lifting at the same time doesn't work:
21:20:19.958 From Port 1 Note On 1 A5 59
21:20:19.959 From Port 1 Note On 1 B5 68
21:20:20.500 From Port 1 Note Off 1 B5 64
21:20:20.502 From Port 1 Note On 1 A5 64
Any ideas what this problem might be and how I can fix it? I'd really appreciate any help.
