mini grand & sustain pedal issue

[cplaza]

Recorded a live Latin Jazz quartet & the keyboard's piano voice was not good, so I hooked up a midi cable to the mini grand virtual instrument, which sounds A LOT better. While mixing, I noticed that intermittently it seems that the sustain is not going off when it should. The midi sustain track shows that the pedal is in fact being released, but either the plug-in or PT 11.2 is not following the command. When repeating the same passage or phrase, sometimes it works correctly and sometimes it doesn't.
Using PT 11.2 on W7 Quad core with RME Octamic-d, RME UFX. PT performance monitor shows that CPU util is at less than 10%, memory util is at 10% of 12GB, Disk util (2TB RAID 0) is at barely above 0%. Has anyone had experience with this? And if you did, how did you fix it?
Thanks...best regards to all.

Take a look at the MIDI note events that he played and see if the pedal is being tapped right at the exact time that the note releases. If so, then that can be interpreted as:

Note Off - then sustain (which means no sustain). But when he played it, he heard a sustain.

The difference being the MIDI instrument he was hearing vs the one you are now playing back through. Different sensitivities to the race condition event. Different latencies perhaps in what you recorded vs what he heard.

Lots of ways to fix that perhaps. Shift the sustain pedal to a few ticks earlier perhaps to get rid of the race condition.

Just a thought. I recall having something like that happen once.

+1 for Choppah. MIDI note off, when timed with other events, can cause unexpected "interpretations".

maybe it´s the infamous midi-sustain bug…

workaround is to deactivate midi-merge

Thanks to all for the suggestions...Right now tracking in the studio for a few days & will re-address midi when I get back to mixing. fyi...Since this was live outdoors & keyboard player was only hearing the PA, he was not hearing the midi track, so this is strictly a mixing issue. I will report back at that time.

Thanks. It did, in fact, to be a timing issue between the note and the release of the sustain pedal. Thanks to all!
