I think I first spotted this in later builds of n-T6.
When creating a clone of a track, even with all four associations un-checked, ie, “Mixer settings”, “WAV files”, “Vol/Pan” and “Effects”, the prg refuses to separate the original track from the clone. Un-arming the original track and then arming the clone doesn’t work, it re-arms the original track thus making it impossible to record to the clone.
thanks for the bug report. I was able to reproduce and fix the problem, the next build will have the fix.
