Monitoring for practice
I often use ardour to assist in practice or to experiment with different improvised parts. In the pre 2.0 versions of ardour, I would just arm a track and hit play and I could use ardour to practice difficult sections of music, improvise etc using ardour as my amp. At an point I could then hit the main record and see how I'm doing by recording a sample.
Now, if I arm a track and hit play, the track goes silent. This must be something easy to do, but I haven't been able to grasp it yet. I want to use the ardour mixer because that is where I hook up various effects, and then to be able to just hit record is a click away.
