Hi Larry and RHARV,

Thank you both for your post.

Under my setup the uMIDI/022 connects to my PC via USB and to my Midi 'mixer' via its 2 midi cables --- the 'mixer' consists of a Roland MPU104 master unit connected to n MPU105 slave unit. This arrangement allows connection by midi of any 1 of 5 master inputs to any or all of 5 slave inputs. Under Midi,I have therefore theoretically the facility to connect as applicable my Windows XP or Windows 7 PC's to my Roland RA95 [GS] midifile player or to whichever of 4 different synths I wish.

The 'memory' problem with PT is preventing connection between the Windows 7 PC and the various synths and Midifile player because in PT the only Midi out that I can obtain is Microsoft GS wavetable synth. Under Sonar X3 and Sonar Artist I can as well as wavetable also connect to the synths/midifile player via uMIDI/022. With PT I would like to be able to connect with the midifile player.

I looked into your suggestion of a midi loop but midi thro is set to off in PT and the linkage of the midi network is such that as configured a loop is not possible when connecting the Windows 7 PC via the midi mixer to the RA95 midifile player.

Could I ask what midi interfaces you are using with your set up?

Thank you for your advice

Regards,

Peter
