[sdiy] Seq stop mid song, best silencing practice?

[grant at musictechnologiesgroup.com]

Another thing I'm playing with (and I apologize if this is re-inventing
the 80's -- I've been in suspended animation since then)... You're
playing a (polyphonic) sequence and then stop it in the middle of the
tune. What's the best way to turn off the notes that were playing as the
sequence was interrupted?  

1) go through the list of notes on and turn them off. 
2) CC 123 (all notes off)?
3) FF reset.

Again while playing with my JX I noticed that it supports (3) but not
(2) so that tells me that (2) might not be that widely implemented. (3)
is a bit harsh so that tends to point toward (1). You people that have
been doing this a while concur?
