Be careful what you wish for..! One of the problems with arranger modules is, unless specifically designed to be a module, a lot of front panel commands (buttons) don't have MIDI codes. If you convert the keyboard arranger into a module, your main keyboard may not be able to select (from its buttons) things like Bass Inversion, ritardando/accelerando etc..
Yes. My desire is to place the module on a stand tier above the keyboard I'd be controlling it from, so I'd still be using the PA1000's buttons and screen for all operations. But I'd be triggering it from a keyboard action I prefer, which will also provide some additional functionality of its own. I'd even have the option to combine it with different keyboards, depending on the needs of the gig.
I actually have a number of boards I'm thinking I could combine it with (61, 76, 88) any of which would give me something I prefer, and while total weight (keyboard and module) might in some cases be greater than the weight of the PA1000 alone, no single piece would be as heavy as the PA1000.
