Ya, it sounds like you must have hit some sort of transposition setting inside SX then. I wish I knew more about it and could help you out, but I havn't done any transposing in SX yet. If it's not readily appearent in poking around, I'd check the index of the PDF for MIDI, transposition. Possibly in the Preferences section?
Anyhow, regarding v1.03, I completely understand the if it ain't broke don't fix it philosophy...since my system runs stable I always wait a week or more after new versions are introduced to see how it pans out wiht all the users. 1.03 is regarded by everyone as extremely stable and did not introduce any new bugs, unlike 1.05. Here are a list of bugs it fixes:
FIXES:
- MIDI Thru Timing improved
- No more Audio Dropouts
- Undo History doesn't get lost anymore
- Master Setup Preset can be restored correctly
- Various SOLO / MUTE improvements
- Window-Layout related crash fixed
- Stepfilter plugin now restores with correct preset
- Houston: The "Instruments" and "Groups" fader banks work again
- Hidden Mixer Channels are now skipped when navigating the channel selection with arrow keys
- MIDI Send FX routing is now saved and restored always correctly
- Possible crash on rendering crossfade fixed
So if you think any of thesemight apply to what your doing you may want to dig up the upgrade to 1.03. Like I said, I'm not sold on 1.05 or 1.051 yet, so I am waiting a bit.
I don't use wavelab....my cousin got me hooked on Soundforge 6.0 and I love it so I use it for my post production needs.
Anyhow, good luck with this midi stuff...hopefully it's a box that accidently got checked or somthing simple like that.
