|  |     I've not attempted to sequence live w/ my D20, but I can offer some
    suggestions. To change reverb settings, etc. would require either a
    message via sysexe, a bulk dump, or (of course) manually changing it.
    If your external sequencer records sysexe, or xmting sysexe buffers,
    then that might work. I don't know how complex your backing parts are,
    but you might be able to combine more than one song (live) into one
    disk file. The D20 sequencer can record up to 500 measures (provided
    note limit is not exceeded). You could record the first backing part,
    then have a few blank measures, then record the second song without
    starting back at the first measure. The D20 would look at this as one
    song, but live you could either stop/start the sequencer, or just play
    straight into the second song. Another possibility would be to record
    song1's backing parts on tracks 2, 3 & 4 and song2's parts on tracks
    5, 6, 7 & 8 leaving you track/channel 1 to play live. Mute tracks 5-8
    when playing song1 and mute 2-4 when playing song2. Depending on
    tracks, amount of notes, etc., you might be able to record song1 on 2-4
    measures 1-100, song2 on 2-4 measures 105-220, song3 on 5-8 measures
    1-120, song 4 on 5-8 measures 125-230 for instance. With this scenario
    you'll still have to change reverb manually. This is pretty klugy, but
    without any external gear, or sysexe transmission, it may be all you've
    got. Anybody else have suggestions??

|  |     Sounds like a job for a DataDisk. If the D-20 is anything like the D-10
    (I think it is), the only way to change the reverb setting for tones is
    via a SYSEXE dump. This can be done to the DataDisk, and then
    down-loaded before the song when you need to change patches. I suspect
    the load time would be a few seconds to maybe 10-20 seconds. With the
    DataDisk/SQ you could then play the sequence in real-time right off the
    disk.
    
    Frankly, I don't understand why you would want to bother changing
    things like the reverb settings during a live performance. Maybe you
    give audiences more credit than I do for being able to discern subtle
    differences in the quality of the sound (maybe you just play to better
    audiences :-)). I *never* use SYSEXE to load my synths during
    performances. I have them configured with one standard set of tones,
    and given that they can support (collectively) hundreds of tones, with
    thousands of possibilities via layering, I find it better not to fool
    around reconfiguring things during performances.

    Firstly thank you for your help, what I am going to do is make up
    the sequenced backing using the D20 and then record that on to a
    MMT-8 then to data disk.  So live I will load say 10 songs from
    the data disk to the MMT8 and I can then call any of them up instantly
    the D20 should recieved all the patch change info to select the right
    sound for the right part, but I may have to just suck it and see
    with the reverb.
    
    Thanks Again 
    P.K.
