MISC. Controls the tempo of the current project and the metronome.
On the top, two controls allow to set the tempo (bpm) by unit and
decimals separately. You can also set the tempo by tapping the
beat on the label, at least four times.
In the central area two buttons are to stop and play/pause the execution
of the music.
The knob on the low-left corner controls the volume of the metronome.
This module doesn't affect the sound and can be placed at any position in the chain
of the modules.
