1) Session 8 MIDI window not configured correctly (Automation Receive Internal enabled, Channel = sequencer track channel).
2) Select another MIDI port for automation and timecode then re-select the Session 8 port.
3) Corrupted Session 8 application (reinstall S8).
4) MIDI Map in Session8.ini missing, or contains incorrect values (all zero). Throw away MIDIPRTR.DLL, SCSI_DSP.DLL and SESSION8.INI, then reinstall S8.
5)Check C:\Windows\System.INI file. Make sure Midi1=Digimidi.drv. If there is a "Midi=" then change that to another number (eg. Midi2=...) just so long as Digimidi=Midi1. When the software loads it looks for these Midi #'s and renumbers them so Digimidi can be #1 but it cannot see a plain ole "Midi=" therefore it can't renumber it and will conflict.
6)If it doesn't work and everything is setup correctly then there may be a problem with Windows Midi Mapper. You will have to use a recovery disk or Windows disks to reload Windows. Midi Mapper may show up and may appear to be functional but reloading seems to be the only viable option.
