I have a simple project (with some VST plugins and some .wav samples).
Tools > Macros > Select unused channels does not select one particular unused channel; however, it selects all other unused channels.
I have now triple-checked this problematic channel manually, and I'm 100% sure, that this channel is NOT used anywhere. It is even not bound to any mixer channel. So, the "select unused channels" option does NOT select one particular unused channel.
Has anyone ever had such a scenario? I have tried restarting the DAW, restart the PC, etc., nothing helps. Note, that other unused channels are being selected with this option.
Side-note: I use FL Studio since it was Fruity Loops (around 20 years for now).. and I'm not a beginner in this.. yet, I have never encountered such a problem.
