Electronic drums with Lightpipe

[JohnE.]

I've ordered and am awaiting delivery on an Alesis Mastercontrol. This firewire audio device has 8 analog inputs, a 2-channel S/PDIF input, and two 8-channel Lightpipe inputs.

Our drummer has a Roland TD-20 based custom made electronic drum kit which has 8 analog outputs on the "brain" (separate mono outputs for the snare, kick, hi-hats, ride, toms, cymbals, etc), along with the analog 2-channel "master" out and 2-channel S/PDIF out. It's a real shame the TD-20 doesn't also have an 8-channel Lightpipe out for the separate mono instrument outs, as this would allow me to put the drum kit on a Lightpipe into the Mastercontrol and still have the analog inputs available and would eliminate an A/D conversion in the signal chain.

So, my question is - does anyone know of an electronic drum kit that has a Lightpipe out? My initial google search didn't turn up anything, but I'm not familiar with enough edrum manufacturers to know where to refine my search. I tried Alesis and Roland but those are the only manufacturers I know of and they didn't seem to have such an animal.
