Your welcome Akira
I have the musical ability of a deaf chimpanzee with it's hands tied behind it's back, but some of the 64 channel Octamed stuff sounds ok to me. You just keep making individual tracks and it combines them all together on the HDD. 14 bit sound isn't as 'loud' as 8 bit for some reason. I never got past a drum beat and two chords myself.
If I remember rightly, Midi files played on Paula sound so feeble. There was that build it yourself Yamaha XG sound box that CU Amiga did, which sounded interesting though.
