OK - I've finalised this version, 1.0, and called it "MoogVoyager_v1.0" - if rather unceremoniously. I've updated the images in the first post to show you two new tabs.
The file is here: http://liine.net/en/community/user-library/view/198/
if you'd like to download it for your Lemur app on iPad.
The Program Changer is mostly functional, and will select and de-select presets correctly. Select your preset and it becomes active. At this stage you need to hit it again to de-select it before you're returned to the default of Preset 1 - from which you can choose another preset.
The Bank Select feature doesn't work yet, and until I find out even if you can select banks via MIDI it'll stay dormant.
If you have Lemur, an iPad and a Voyager, please give it a go. I'd like to hear back from those that might try it out - especially if you have a Voyager RME (rack mount edition).
