Just got through Mistheria Keytar Masterclass ..... it's a fantastic resource for learning keytar tricks..... and Roland AX synth, in particular (which is the instrument he uses throughout the course).
I recommend it to everyone using the Roland Ax synth
Becoming a keytar performer on the AX synth
Re: Becoming a keytar performer on the AX synth
Is it more about keyboard technique, controllers or programming?
