What sequencer are you using? If you use bars n' pipes, you may like to try the 'tripple play (plus?)' midi interface. It allows three seperate midi banks (3x16 midi channels). If you have a lot of gear, it can be handy. There are diy plans for these, and a number floating around, which come on sale reasonably often. o/w, serial interfaces are OK too, and also very easy to make for amiga's, as the serial interfaces support the midi clock frequency.
