Summary	0001392: Long samples with volume slide commands breaks "maintain sample sync on seek"
Description	If this has already been submitted, or fixed in newer versions (I am using 1.27.06.00), I apologize. Bug fix request: there's a bug most noticeable with very long samples (such as vocal recordings)- if you use volume slide commands (c01, d02, etc), it breaks "Maintain sample sync on seek". If you seek later ahead, the long sample will play nothing unless you remove the cxx and dxx commands occuring prior to the seek point. I could produce a SSCCE to demonstrate this if needed.
Tags	No tags attached.

Has the bug occurred in previous versions?
Tested code revision (in case you know it)

Saga Musix 2020-11-26 15:36 administrator ~0004518	There are a handful of commands that are difficult to keep track of (either they are expensive to compute or require non-trivial code changes), so those are not supported by that option at the moment. However, volume slides should be no longer on that list. If this has already been submitted, or fixed in newer versions (I am using 1.27.06.00), I apologize. Please ALWAYS update to the latest version before reporting an issue or feature request.
