I'm in the process of integrating a new PC in my studio and ran into problems when using Vienna Ensemble Pro 5's external MIDI ports feature. I intend to route MIDI through ipMIDI (for several reasons this suits my needs better than VEP built-in MIDI) which used to work out pretty well in combination with VEP 5 on an older computer (workload now being taken care of by the new PC).
Unfortunately, for some reason, VEP doesn't receive MIDI at the appropriate port that was used on the sender. What I mean is this: PC1 (Sequencer, Logic Pro 9.1.8) sends MIDI from ipMIDI Port 1 to PC2 (VEP 5 Sever) which doesn't received MIDI at ipMIDI Port 1 BUT at ipMIDI Port 9! So that's what I call weird :-).
I should point out that this only happens when using the VEP Sever application. Everything's fine in VEP non-server. All firewall, etc. turned off - I suppose that there must be some interference in the listing of VEP-midi-ports and external midi ports.
Has anybody experienced similar issues and can help? Would be greatly appreciated!
