Tascam US-224/428 MMC Implementation
This is my latest patch against the alsa-tools tree (as of todays CVS
HEAD), regarding the us428control MMC implementation as for the Tascam
US-224/428 audio/midi USB control surfaces:
us428control now bumps to version 0.4.4.
Interesting points are: jog wheel dialing is now alternating between
spitting out some MMC-Step or MMC-Shuttle messages, depending on transport
state, instead of those MMC-Locate(s) which was an early implementation
mistake of mine.
Controlling ardour with (my) US-224 is getting much more fun now :)
However, there's still some little annoyances due to my lack of advice
regarding ardour's Play/Record control behaviour:
1) Ardour doesn't seem to send out MMC-Play messages when one starts
transport within it (e.g. by clicking the playback button widget).
2) Ardour doesn't seem to react against MMC-RecordPause, which I assume
(probably erroneously) it would be equivalent to clicking on its record
widget button.
3) Sending a MMC-RecordStrobe message to ardour has the strange effect to
start playback while toggling recording off instantaneously.
AFAICT these issues seems to be specific to ardour (0.9beta18.4), not to
us428control which is just sending out the proper MMC messages. Or that I
think.
I would like to settle all this before I'm going off on holidays. Hope
it's welcome and on time for the imminent alsa dot-6 release :)
