What was the source of the errant SMF's? Were they commercial GS SMF's, XG, made from scratch on the G70, Recorder captures of G70 arranger play?
Sorry I missed the freeze reference.
Did you have an SRX card in the G70, was the sequence pointing to that?
Also, you remember this thread from Roland-Arranger.com?
http://www.roland-arranger.com/smf/index.php?topic=1948.0Seems some of the kits may be missing from the PC#/00/32 table. Have you double checked to see if the kit called up in the SMF has a kit in the BK with the same PC#/32/00?
I seem to remember some styles that were supposed to call up SRX basses, and kept calling up an trumpet, or something along those lines. As soon as I Makeup Tooled them and saved, they played fine.
In all fairness, when I get a new piece of gear, I generally redo
all my SMF's. Not really much point playing old SMF's that point to the old sounds... Might as well not have newer gear for that!
