I did have some success last night following your advice searching for the (PC) feature on the sequencer. I was able to record a specific voice for each track, assign it a midi chann., and record. I did this on 2 tracks using 2 voices on two midi chann. Then I re-set the YS200 to a different voice (other than I just recorded with). When I played back my recorded tracks the sequencer automatically switched the synth back to the voices I originally set to record with. The only thing I had to set manually was the midi receive channels on the synth. I can live with this (for now).

A couple of new questions. It seems that with each hurdle I over come, 10 more pop up.

1. The YS200 is capable of playing up to 8 voices at once. I can get some very nice sounds combining 2 or more voices. How can I get the MC-50 to save a (PC) for 2 voices on the same midi track? Up to now, I know how to save 1 voice, but what if I want to record using 2 simultaneously on the same midi track?

2. I'm wondering about the bulk dump feature on the YS200. I tried it last night but it didn't seem to do anything. Someone mentioned that the MC-50 should be set to record, that was something I didn't do. I just hit bulk dump. It only took a few seconds to complete. Tonight I will try it again with the sequencer set to record. Maybe this is how you can save multiple voices to one midi chann.

3. The manual for the MC-50 says "each phrase track can store musical data of all midi channels. The MC-5- has 8 of these tracks for a total of 128 tracks of midi data".
Any idea what this means and how it apples?

4. The YS-200 has 99 pre-set and 99 user voices. When I input a PC on the MC-50 it just asked for the voice number, any idea how I might input user voices (U) as opposed to the pre-sets (P)?
