Please explain to me what exactly you are trying to do.
1./ Are you trying to control an external vocalizer (in place of the internal one) as you play LIVE (with styles using either your left, right hands or full keyboard mode) OR
2./ Are you trying to play a MIDI FILE on the SD1 and have IT control the external vocalizer?
With case (1), you will have to just play normally and have the External unit pick up on either LEFT/RIGHT or full mode (esp. if using Digitech, you will have to define the keyboard range to pick up .. unless when using VOCODER in which case you will tell the Digitech what KEY you are playing in and it will proceed from there regardless of midi connection to unit.
With case (2) you will have to go into MIDI and set the required track that you want to control the vocalizer to VOCALIZE. Now be carefull!! Certain disks (such as TUNE1000 already have vocalizer 'notes' encoded within their songs. In this case you DO want the notes from the actual tracks to be played back and so will have to set this track to VOICE and NOT VOCALIZER. When set to VOICE, the actuall NOTES are transmitted to the DIGITECH. As an example let's say track 5 is what has the vocalizer notes, you will have to to go MIDI, select track5 and make sure it is at voice (usually piano). Now on the DIGITECH, it should be set to receive on track 5.
Again, let me know exactly what you are trying to acomplish. The MIDI settin within the VOCALIZER (along with all the ohter functions under VOCALIZER-EDIT are for the internal Vocalizer only!!
Thanks,
