Thankfully this doesn't happen on my soundcard.

If there is too many rapid events, on the SW1000XG it slows down output, then fast forwards as it tries to catch up on realtime playback. How does the MU100 fare with that situation? (Test? Tsu Ryu's Metroid Fusion title piece)
Blitz Lunar wrote:- Overlapping notes on the SYXG50 just increased their volume. On the MU100, they cause phase/comb filtering (like most other midi devices do.) SORRY ZENKUSA YOUR TIME IS UP.
- XG resets are required before tracks for yamaha XG variation banks/instruments to work (a GM reset will not allow for XG instruments, it'll always use default GM patches.) However, on the SYXG50, variation banks worked irrespective of any type of reset message beforehand, as far as I am aware.
On the news of overlapping notes, this combing behaviour
proves MIDI being pseudo-simultaneous, in action!

It's really noticeable with drums.
As for GM reset only, on the S-YXG50 it prevented the ability to use any of the variation banks for my version. (v4.21) and acts accordingly with the SW1000XG.
Blitz Lunar wrote:- The SYXG50 has the "MU Basic" GM patch set. The MU100 can use this set or use the new "MU100/SW1000XG Native" set, which changes many instruments. Haven't worked out how to switch between the two, but the native one sounds better on the whole.
It's on the manual, or that sysex message on some japanese page.
Oh yeah, if Lunar's not willing to do certain files, I'll gladly record them for you. (Private Message please.)
