kid kasio Posted January 17, 2012 Share Posted January 17, 2012 Hi This is my first post so you may have to bear with me while i explain my problem Firstly does anyone know whether Mainstage 2.2 has the option of being able to send midi notes to an external device? ( a bit like the "playback' plugin but with midi instead of audio) because if it does all my problems are solved and I will go and buy it now!! If it doesn't then it certainly should ! read on and maybe someone can help me Im running mainstage 2.13 on a macbook pro with OSX 10.6.8 with an RME fireface 400 audio unit. Mainstage is set up so for each song in my concert there is 8 channels of playback running (drums, bass, keys,etc etc) there is also a channel on the mixer strip of each song sending midi clock data to an external sequencer. The external sequencer is set up as the slave so when i change the song on mainstage the metronome on the external sequencer changes in accordance with the tempo of the song in mainstage , so far so good. when I press play on the external sequencer it sends a start/stop midi message to mainstage which starts the playbacks , it also sends out the root chords of the song which i have pre recorded in the external sequencers memory to a voicelive touch box which tunes my vocals in accordance with the song. I noticed that the tuning on my vocals was sometimes slightly out so I ran a midi keyboard from the external sequencers midi out to hear exactly what it was playing and noticed its sometimes out by about half a second. The problem is theres no rule to it, sometimes its early sometimes late sometimes bang on. I've tried changing buffer sizes and i've disabled any softsynth plugins I had running but nothing changes i just cant figure it out The procedure for a song normally goes like this 1. I'll click on a new song in mainstage (while in performance mode) 2. Mainstage will send the midi clock tempo for that song to my external sequencer (i can tell by the metronome light flashing at a new speed) 3. i'll turn the metronome on my external sequencer on and hit the play button bang on the beat in time with the metronome 4. The play button on the external sequencer will simultaneously send a start midi message to "playback" in mainstage while sending the midi notes stored in its memory to the external voice autotune box 5. all the 8 channels of playback start and all runs in time with each other but the notes being sent out by my external sequencer are not synched with playback . sometimes thy're early sometimes late sometimes in time. I have accounted for the slight latency between pressing play on the external sequencer and the playback starting in mainstage by shifting the midi notes in my external sequencer back slightly but the problem is the sheer inconsistency of it! if it was always late or always early that would be fine but why is it so inconsistent? what is causing this inconsistency? and can it be remedied? Any help would be amazing! Thanks Nathan Link to comment Share on other sites More sharing options...
