Hi Stuart,
As has been noted above, If you have a Motif or other Yamaha instrument that uses the MSB 063 for Normal Voices and MSB 062 for drum kits then the dummy Voice pack loaded in Genos will work. But also noted above is the fact the the Voice Set file is transmitted very fast before the Motif can load its Voice with all the DSP, Filters, Arps, and other settings, so the Voice Set settings won't apply... but if you select the Voice a second time after the Voice is loaded, or maybe select a User Voice with modified settings... the Voice Set settings will then be applied to the external Voice.
When I select an analog Voice for my AN plug-in card using the midi solutions Event Processor to re-map the MSB 063 to MSB 036, the Analog card Voices load correctly including Voice Set settings because the AN Voices do not have all the preset setups as the Motif.
So... I'm wondering if there is a latency issue with the iPad
Here is my custom MIDI configuration for when I use the dummy Voice packs:
R1, Ch1 - Local Off
R1, Ch1 Transmit: Note, CC, PC, PB, AT
R1, Ch1 Receive: CC, PB, AT (if the Ipad Voices have an arpeggiator, you might try receiving Notes as well)
