Thanka rikkisbears, you've been very helpful. I was aware about the MIDI in/out, and I will inquire on the Yahoo DGX board. Anyhow, it looks like I will be waiting til June for the weighted key version (YPG625), so I'll have plenty of time to check out the ES4 and some GEMs.

Too bad I won't be able to add a vocal to the headset out. Can't have everything, I guess.

Took another trip to GC. I'll post about that elsewhere.

L8R,
Rick
