Was not impressed with this keyboard. The keys must be pressed really hard to get them to activate and its overall sounds are nothing special. So added a 1/4 inch output and started on bends (heck they could only improve it). A potentiometer was wired into the power to simulate low power batteries (causes some distortion and glitches). Did not wire in a reset switch as the on/off switch was wired to act as such. Then added 12 buttons to act as glitch buttons. Some will initiate a tone on their own while momentary pressing others will change the effects of the first button.
