I was at a friend the weekend and had my MB64v2 to jam with Reason2. Our setup was [his velocity-sensitive keyborad’s out]-[MB64 in] [MB64 out]-[PC-Midi In] with midi-merger enabled and the Keyboard sending to channel 16.
The problem was that (at least on reason2, i couldn’t install midiox cos we needed that stupid windows-installer!) the keyboard sent note-on commands correctly but instead of note-off it sent again note-on, letting notes ring!
The MB64 sent correctly note-on-off events.
After resetting the keyboard to transmit on channel 1, the problem was solved!
to your MIDIbox - thereafter MIOS will send the whole SRAM content, it can be recorded with the SysEx tool of MIDI-Ox (see also http://www.ucapps.de/mios/mios_backup.txt). Store it under the name “sram.syx”
Thereafter create a backup of the flash/EEPROM and BankStick (if available) and send me the 4 files, so that I can reconstruate the scenario.
