Clicking the Multi-Track checkbox or typing 'M' toggles between single and multi-track modes. Entering the Multi-track mode will stack the open tape windows, putting the active window at the bottom. When a Tape Window is active, you can edit and fade its content.
If more than one tape window is open in the Multi-Track mode, a click on a non-active tape will make that tape window the active tape (and therefore the active track).
Jasmine will play all the open tape windows as if they were tracks of a multi-track session.
The Fader indicator at the right of each tape window (and each track in multi-track mode) shows its volume at the cue point during playback. Mixing of the tracks (tape windows) happens when multi-track playback is started.
The initial fader level for a new recording's Edit file is set to 0 dB.
The Fader control, when on, only affects the front tape window. To use the Fader on another track, click that tape window, or use tab key to walk through the open tape windows. Note that changing windows automatically turns off the multi-track mode.
