Your primary problem with a TOTL arranger module is that the physical buttons themselves are a LARGE part of how we play the thing, and they need to be as close to the keyboard as is humanly possible. No remote keyboard offers enough buttons or flexibility of programming them, and no arranger has remote codes for ALL the functions you are going to need...

Modules used to be great when they were fairly simple beasts (used an RA-90 for quite a while), but as laden with controls that are needed for their operation and touch screens that can't be obscured by other gear as modern WS's are, I just can't see how it would physically be possible to get the two close enough together to work well.

I think, on the whole, we are pi$$ing into the wind on this one What MIGHT be more worth our time, and might actually be responded to if enough of us got a hold of our manufacturer reps and dealers, would be to DEMAND that full MIDI implementation be restored to arranger operation, and a unified, cross-manufacturer set of MIDI codes for arranger operation.

This would simply be a matter of software, and wouldn't require the manufacturer to tool up for an entirely new (and VERY niche) product. If the arranger can't be made into a module, that can be controlled by a WS, why not control a WS module (or another arranger) from the arranger you are playing? Pretty much all the WS's have rack module versions. It doesn't really matter WHAT MIDI keyboard you are playing on, as long as it can send any MIDI code you want it to...

But full MIDI functionality MUST be implemented for this to work. I have long said that, rather than hold my breath waiting for the PERFECT arranger to come out, it already (at least for me) exists if I could merely MIDI two current arrangers together. No reason why I couldn't add a WS module to the mix too... But while MIDI transmission and reception are as barebones as most manufacturers make them, this is a pipe dream.

C'mon, Yamaha, Korg, Roland, Ketron... it's ONLY code, no hardware changes needed in the slightest. Every knob, button and slider should be able to send a user defined MIDI code, and every function of operation should have a user defined code. Make it an 'expert' setting that normally hides from view if you don't want to frighten the 'home' users.. But you'll sell a BOATLOAD more gear if two can talk to each other. Otherwise, we GOTS to use just the one

Your choice. We are waiting, with our wallets ready...
