I don't have any of that gear, but check that an option like "note on/off" is turned on in the MIDI setup menu on the Juno-D. Also check in Logic that it's midi is setup right. Logic could also be receiving sustain pedal MIDI info from the Juno. Anyway, that's all I got.

I believe they haven't changed the bridges on those. If it looks standard, then the thread and shape should be a standard fender tremolo arm that you can find basically anywhere guitars are sold.

Roland Juno gi program error problem

You need to turn off the echo of the MIDI that sends the signals back to the Juno. When near simulataneous MIDI signals are mixed the decoder can receive "partial" messages that re-trigger the notes and then miss the note off commands. If you can't find the setting in the software, disconnect the input to the Juno MIDI while recording it.

There will be a threaded hole on the tremolo block. The tremolo arm simply screws into this.
