In Sonar Platinum, I have a 39 minute 16 Track MIDI project that is heavy in Sysex information.
When I set the MIDI "Prepare using" to 500 ms, the project crashes Sonar Platinum while playing past the 10 second mark. At the point in the project, it comes across a sysex bank pointing to 89 bytes of sysex data.
If I set the "Prepare using" to 290 ms or less, the crash does not occur in Sonar Platinum.
Note: The sysex needs to be there as it sets up requires parameters for the external synth, so removing the bank is not an option. It would not sound as intended.
Now, I load the same project into Cakewalk by Bandlab, set its MIDI "Prepare using" to 500 ms, the project gets past this 10 second point where the sysex bank is without crashing.
Either I'm imagining this or the Bandlab team did actually fix something.
Even if you don't see a visible GUI change, there are likely bug fixes under the bonnet that makes things run a little smoother.
