I love to adjust my sounds real time whil playing modern style with knobs. Every synth has atleast a few of them...Arranger keys have none. I am looking for a device just like the phat.boy (that is no longer avilable) that lets me send these parameters over midi....

Does anyone have a solution for this?

(it would also be great if it looked less flashy then that phat.boy)

Orriginally i had the idea of stacking this with a Pa2X (which can be set up to use such a device) but since i decided not to go the Korg road because of lacking support for 3rd party styles, it makes me wonder if it would also be possible to use it with Wersi and the other top knotch arrangers...
