Hi all, I am having problems recording MIDI with MTPAV & Logic Pro 8 My system specs are: System: G5 2.5GHz, 16GB Ram OS: Tiger 10.4.11 3 MTPAV's 12 Rack-mount synths Rosetta 800, Big Ben DIGI 002R, Central station Anyone know why I am getting delays, dropped notes & latency when attempting to record MIDI using external synths ? Recording Software synths seems to work fine. I am just having no luck recording external MIDI. I can play patches from any of the synths without recording but the minute I press record notes/chords get dropped randomly and the system seems to hiccup and lag so what's recorded is useless. I've tried adjusting the audio device I/O buffers (32-128), using low latency mode, temporarily disabling the DAE Engine, turning off MIDI SYNC Clock, MTC, MMC etc. On a more positive note I recently had success when plugging the S90 controller into the DIGI-002R the MIDI Recording works fine as it should. Also tried recording MIDI using the same 3 MTPAV's as I have for years in Digital Performer 4.6 & Pro Tools 7.4LE and had no problems recording MIDI on any of the rack-mount synths connected to any of the MTPAV's I am new to Logic so it could very be I have a complicated setup for The Logic world that requires a little more "setup knowledge" than I have. I am told that perhaps creating "Multi-instrument" objects in the environment would help. I think these were created for me somehow pulling the info from theAMS (Audio MIDI Setup) Limiting each rack-mount synth to a specific channel, but I've never had to limit my MIDI setup to 1 channel per synth in any other sequencer before. All MIDI synths allow for 16 channels in "Multi-timbral" mode so why would I have to reduce the number to possible channels I can record per MIDI device from 16 to 1? Doesn't make sense to me. I know that Logic merges all Incoming MIDI Inputs. Is that why? Also I've heard that Logic & The MTPAV are notorious for not playing well together. Not sure why but that's what I heard. I've called Apple Tech Support on this & they weren't able to help. Also called MOTU and they said there aren't aware of any special configurations needed for the MTPAV to work with Logic but they would try and recreate a scaled down version of my set up and recreate the problem to help with a solution but that a while ago. Are people able to use MTPAV's or are they all using the old Unitors? I've never heard of latency effecting MIDI recordings? Can anyone suggest anything? I've been struggling with this problem for over 3 weeks!!
