Dear friends of the Forum, thanks for accepting my membership.
I am a pianist and composer of classical music, but always fascinates me and work with electronic music.
I have synth "old": I4S Korg, Korg 01R / W, Roland SC88 and a Yamaha TX81Z.
My problem is just the TX81Z: I can not find the file anywhere instrument for Cakewalk and I can not even edit an.
I can not figure out how to write the file so exact that I may have in the cakewalk 5 benches sounds together,
or A-B-C-D-I
I thank you in advance for the help that you give me.
A friendly greeting.
