How about a motion-record button, like I can find on my other gear (Kaoss pad & Parameter lock recording on the Elektron Machines)
togehter with a 32-step Pattern-Sequencer like the Korg Radias ( this would mean the unit would be larger in depth and priced higher )
Nobody would want to buy another synth anymore...
Display size should be x2 or memory A/B' ed ( to quickly select between two patches and their corresponding parameter page you want to tweak.)
Because for me, because I'm moving back from plugins & softsynths to using external gear only, with a couple of samples trown in occasionnaly.
Live Jamming is just more fun.
Have a great time making music.
Thank you Acces for the countless Hours of amazement.
