I have played keyboards in bands for decades and never really taken any notice of the midi potential. I am not a technical person but I love the idea of being able to use Midi live on stage. I have just switched from a Roland A90EX to an Electro HP4 which is much lighter and has awesome sound quality. To start with, I need to design a way of switching between patches on the new keyboard as fast as I could on the old one where I just tap in the patch number and up comes the sound I want. Can anyone point me in the right direction please?
