[Lmuse-user] New: Monitoring feature

[termtech]

As per recent email discussions:
In git master now:

- Midi Tracks and Wave Tracks have a 'Monitor' button.
Push to pass input through to output.
Midi Track 'Midi Thru' was re-branded and re-purposed as 'Monitor'.

- Meters: When in 'rec-arm' mode but not 'Monitor', meters are active.
Wave Tracks: NOTE: Be aware that when 'rec-armed', the meters show
the RECORDING levels pre-fader/rack etc. NOT post-fader.
This was a technical necessity, but actually has benefits: The user
can see the actual recording levels before the signal hits the
disk.

- Since monitoring is important and can cause unaware unwanted mixing
or missing audio, the 'Monitor' buttons flash to indicate being active.

- TODO: Add an Arranger track list 'Monitor' column.
Make Wave Tracks NOT monitor by default ??

- FIXED: Wave tracks now mix playback audio with incoming audio -
you can now hear what's playing as you are recording.
[ That one took some effort. but it was a long standing issue.]

Try it out. Lemme know if any trouble. Comments? Suggestions?
