I tried triggering the expression map with program change instead of key switches and got the same exact results.
I’ve also tried triggering the expression maps with different input sources. i.e. different midi controllers and still the same exact results described above in both CB 8.5 and 9.
I’m pretty sure it’s only related to expression maps as the actual notes and CC data still gets recorded. Although if you can confirm this works on a PC that would be great, as maybe we can get another Mac user to confirm it does not work on Mac.
I’m currently running OS X 10.10.5
Also when testing please be careful with the order of operations I’ve laid out as it is very important when you press the space bar and when you press retro-record.
I’ve also tried enabling and disabling the preference “Snap MIDI Parts to Bars” under the “Record - Midi” preference pane. Unfortunately that didn’t fix it either.
