*EDIT#2 - pics below in a later post!
EDIT - important note, I tested this further and it definitely seems to be a bug. It does not do this problem with the first two or so midi recordings. Then after that it creates parts that reach all the way back to the last recorded part. So if you test this it’s important to do it several times for the bug to show. Record one bar, skip a few bars, record again, etc. Do this about 3-4 times and you will see the newer parts being created in this extended way.
If I record a midi part on a track that already contains a midi part, the newly created part extends past the locators to meet with the previous midi part. In other words it’s like this. I record a midi part from locator position 2 through 10. Then I set the start locator position to 12 and the end locator to 14 and start recording from the first locator using the record button (actually this happens no matter where I start recording between the locators). When recording is done I hit stop and instead of simply getting a midi part that is from position 12 through 14 I have a midi part that is from 10 through 14. All data is correctly placed of course between 12 through 14, there’s just emptiness in the extended part.
I have confirmed this behavior does not exist in Cubase SX3, which is what I came from. It also does not do this in Cubase 6 if I first double click to create a midi part then record. It’s a very minor bug with a simple workaround, of course, but it would be nice to not have to create a part first every time before I record. So can anyone confirm this? Or, if it turns out to be some type of preference setting, like auto-glue parts or something, please point me where to change it.
