Rough idea.
I have had a play with it.
step1: Hook up to Rec unit (tape in/tape out of Mts to Rec unit)
if on Multi 8trk track 8 trk /trk 4 on a 4 track.
Step 2: connect Midi leads to MTS and to device you with to sync with
(my case is a old SR-16 Drum machine)
step 3: disable your DBX for that trk if your Rec unit has it.
Step 4: select Time signature on MTS-30
step 5: Hit record on your multi trk then hit save button on MTS-30
This sends a a high freq from it`s line out to line in on Rec Unit.
step 6: Hit play button on unit to be syncronized
when your duration of time you want is over press save
button again to stop signal.
Play back (8trk running Drum machine)
step 1: rewind 8tk to start of recorded section and make sure your MTS-30 only displays 3x dashes (---)
step 2: press playback on 8tk & after a few seconds your drum machine
should start automatically playing with 8trk.
I don`t as yet know what else it can do progam wise as I don`t have a manual for it.
If any has or knows more I would be most grateful if they could let me know.
