Hi got myself a vintage roland jv1000 connected by a simple MIDI-USB interface. When playing back jv1000 performances than all is well but playing back single patches then MIDI notes just streames rigth out without any MIDI-off. Logic's indicator shows MIDI-off messages but all notes are long. I have reset the JV to default-settings. Maybe one of you understands or have experience of that old keyboard. What can it be, is it the simple 16 ch. USB plug 'n play MIDI-interface or what? So Roland works fine, groups of performances works aswell. Playing single patches fine, but Logic will return the MIDI notes from single patches without any notes-off although the MIDI-indicator shows MIDI-off messages in logic. Some-one?
