Hi Kevin,
it's very strange because it's happen only in one of my session. Please note that i cannot update my sparkLE controller to 1.2.2.2 version; i'm still on 1.0.
I will try to described what i did:
1-Last year, i remember i had the same bug in this cubase 6.5 (64 bit) session on window 7 64 bit.
2-I moved to Mac Osx (lion) and had the same bug on the same cubase version.
3-Now i tried it on Mac OSX (mountain lion) with cubase 7 (64 bit): same bug.
4-On windows 8 (64 bit) with cubase 7 (64 bit) : same bug.
5-I said to myself maybe it's a sample bug and load another Spark kit: same bug.
6-I decided to move all my tracks to a template session i have made recently on windows 8: same bug.
7-I started a new fresh session in cubase 7 (64 bit) and import just the midi track of Spark from my buggy session: everything is ok.
Do you know if certain plugins can interfere with the Spark? Because, last year i tried everything on Spark and now i have a SparkLE unit and same bug for both.
The thing i don't understand, it's i have the same bug when i transfer all my tracks to another session but not with a fresh one.
Thanks
