So after a crappy experience with the VR09 I traded it in for an FA06 (approx 14 months ago)
I've gigged with the FA on several occasions as my upper synth/organs board (I've got an SV-1 on the bottom covering stage piano, electric piano, and clavs). Previously I used an Alesis Ion for my top board and while its organs certainly couldn't compare to the "not quite clone wheel" quality of the FA, the Ion allowed me to effectively map any parameter I wanted to the pitch wheel or two modulation wheels - resulting in Nord morph "like" affects.
Then steps in the FA. It's got decent organs (apart from some jaw dropping functionality omissions), but all in all for my purposes which includes performing live, I am unimpressed with the Supernatural synths. Not necessarily the sound quality, but rather I am unimpressed with the inability to assign synth parameters via cc to pitch/mod paddle, buttons, and knobs when used in a performance setting.
Obviously we all know that there is no good quality cost effective available solution for adding drawbar controllers to the supernatural organ, but also, unless I am completely missing the boat, it is not possible to assign controllers to any destinations in the supernatural synths - rather can only assign controllers to destinations of the current MFX effect.
So for instance, if I want use the pitch/mod joystick to change filter cutoff/resonance, etc on a Supernatural synth patch, I am out of luck. Not going to happen. Likewise I can't assign a knob to a CC to control key tracking on the filter.
I've found that really any of the cool performance options provided by the FA06 are only available if I'm willing to utilize the dated sound gen tech employed in Roland's earlier boards - which totally bums me out. Don't get me wrong, many of these still rock - it just puzzles me to no end that Roland releases a new product which much improve sounds but forgot to give us even 30% of the control we previously had to modify the old synth parameters in a live setting.
Hopefully one of you will tell me I have no idea what I'm talking about and all is indeed possible on the FA (without using the touchscreen - using that in a live situation to control parameters is a nonstarter and accident waiting to happen). But I'm not holding my breath. But it would sure be cool...
