Hello Philippe,
I'm not very good in English so maybe I say the opposite of my thought ?!
I gonna give you an example :
on a same song I have 3 parts :
- piano (on the expander) (on all the keyboard)
- organ (on the expander) + Mg (each on the half of the keyboard)
- piano (on the expander)+ CS 80 (on the same part of the keyboard) + Mg (on the other part)
Today I do that with PC and forte of brainspawn but it's not stable... so I gonna buy The Origin keyboard.
I imagine it's not so difficult for the origin to send a program change on the midi output?!
otherwise I'll have to take a footswitch like the FC1010 for recall the preset of the two devices...
In fact I think about a module for send midi parameters when you call a preset, for example for mute one af the expander when you use the other. And play all with the same keyboard...
Also a module setlist would be amazing:
Song1 - preset A
Song1 - Preset B
Song2 - Preset C
Song2 - Preset B
Song3 - Preset A
...
then you can up/down your preset. On stage I don't want to look the number of my preset...
(I suppose I can do it with Bank but sometime you have the same preset many time and it's not easy to update the presets)
I understand that I have to take an expander for accoustic sounds because it's not the job of the Origin, but I don't really want to take another midi controller....
in conclusion I want my Origin and I want to control the world with it ! Roahahahahhah
