Using my Yamaha RX-8 drum machine as a MIDI controller

[BLG]

Is there any way to use my old Yamaha RX-8 drum machine as a midi controller (to control Xpand2 to generate drum tracks)? I think I prefer the drum sounds in Xpand2 to those in my drum machine and I'd rather not buy an external controller. And using the built-in MIDI controller seems like a real pain.



I'm brand-new to Pro Tools, so I'll need detailed instructions.



Thanks in advance!
