I have lots of midi-tracks with synth-plugins that output to an audio bus. Let's call these buses instrument busses. Their output goes to master in.
Then I'd like to have 2 buses with a reverb plugin (C* plate 2x2) with different settings. Let's call these buses effect buses. Their output goes to Master in as well.
Using only only one effect bus (by several instrument buses) works fine.
Using the 2nd effect bus doesn't work and loading this saved session crashes Qtractor immediately.
The difference between the qtr-file that can be loaded (instrument tracks only use the 1st effect-bus) and the qtr-file that crashes Qtractor (one instrument track uses the 2nd effect bus) is only
< <config key="audioBusName">G Rev1</config>
> <config key="audioBusName">G Rev2</config>
As far as I tested the same thing happens when I use an insert-send instead of an aux-send.
