us428control 0.4.5 [RFC]

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Karsten et al.,

After a very long period I've finally got the time and initiative to get
back on continuing us428control implementation details, specially
regarding my US-224 usability as a dedicated DAW control surface.

Almost 3 years ago I had the MMC implementation started but left it in
the bare basic status, that was about the transport and shuttle controls.

Now I wish to have a chance and push it a little bit further and
complete some other things in the process.

Specifically, I'm proposing about the following:

a) SELECT, REC, MUTE and SOLO switching.
b) NULL fader switching.
c) MMC Masked-Write command mapping to REC, MUTE and SOLO[*]

I have already a) and b) working partially, at least for the lightnings
(LEDs) as you can check from [1], with version bumped to
0.4.5; c) will follow promptly on those next days.

I would like your early but valuable comments, whether this effort makes
any sense, specially in regard to the US-428.

[*] I have some fundamental doubts if there's an MMC command information
field for track SOLOing. AFAIK theres only those for track REC and MUTE
status, dunno how can I do the SOLO signaling :( Ah, any hint would be
highly appreciated, specially from someone who has access to the
official MIDI specification, the one regarding MMC Recommended Practices
RP-013 in particular ;)
