Can anyone explain how to control the SD1 Vocalizer from a MIDI file/song (which is playing on the SD1).

Thanks,
Glenn

At first you have to select a midi track that contains the back vocals in midi notes
then usin sysex assign the specific chanel to vocalizer (F0 26 7B 33 00 0F 01 F7 for ch16) you can set the vocalizer on via midi with this sysex: F0 26 7B 36 00 7F F7 or just turn it on manual the vocalizer is set automaticaly to midi mode
you can also adjust the parameters: direct volume, vocalizer volume, equalizer ..... with NRPN in the midi chanel
if you use cakewalk or sonar:

12290=Direct Volume
12291=Vocalizer Volumer
12298=Octave Voices
12299=Singer Gender
12420=Formant Vocal Effects
12421=Frequency Vocal Effects
12422=Resonance Vocal Effects
12676=Volume Voice 1
12677=Volume Voice 2
12678=Volume Voice 3
12679=Formant Voice 1
12680=Formant Voice 2
12681=Formant Voice 3
12682=Frequency Voice 1
12683=Frequency Voice 2
12684=Frequency Voice 3
12685=Resonance Voice 1
12686=Resonance Voice 2
12687=Resonance Voice 3
12803=Limiter
12805=Vibrato Depth
12806=Vibrato Rate
12807=Vibrato Delay
12820=Equalizer Direct LOW
12821=Equalizer Direct MID
12822=Equalizer Direct HIGH
12826=Equalizer Vocalizer LOW
12827=Equalizer Vocalizer MID
12828=Equalizer Vocalizer HIGH

the data for each parameter goes from 0 - 16383

in steps of 128 example value 50 =128*50=6400

Thanks, midimast. I don't use Sonar, but PowerTrack. I'll play around with it and see what I can do.
