Thanks both.
(almost) All of our sequences include a workstation's drum machine, a rhythm sequence or rhythmic accompaniment. Usually, we edit and quantise in the workstation if necessary so adding a click track should be very straightforward. I should be able to make click tracks as midi files for various time signatures. They will then load into one of the sequencer tracks on any model. That does prevent omni midi recording so I'll have to make some templates in Cakewalk and experiment.
We tried SMTPE, none of the workstations seem to send a signal (or I'm not using it correctly).
Thinking further, many of the sequences don't have tempo changes. One of my problems is trying to check which ones do, which was why I'm looking for something automatic (I have been looking for years basically). The process at the moment is:
Record the midi with clock sync, watching and listening for tempo changes.
At the same time, record audio using a second computer and export as mp3.
If any tempo changes, play the sequence again, manually creating a tempo map in Cakewalk.
Save as a midi file.
Minor edits in midiworks if the resulting midi file is not compatible with various standards (GM, GM2 and others). This is usually relatively automated remapping of patches.
Cheers,
Mike
