I was unable to get the PSR-S910's sequencer to generate Sondius-XG midifiles, finding no way to override the selected PSR voice with the requisite Bank Select MSB 97, LSB 112 thru 119. These activate the VL-XG mode of the VL70m, PLG150VL, S-YXG100 and DS-XG but are treated as Bank Select MSB 0 LSB 1 (Key Sensitive Panning or suchlike) by all non-VL XG synths. My Mid2VL program in VL Control Surface.zip could be used as a bit-hack to convert the bank select on channel 1, but it doesn't have the ability to add VL-XG system-exclusive part data (F0 43 10 57 09 xx xx nn F7) as stored in my .syx initialisation files.
