- A new command line option indicates which interface model is actually present (-m us428|us224|mixxx) -- nb. the mixxx mode is actually orthogonal to the us428 and us224 ones, which are in turn both mutually exclusive, so that more than one -m option can be specified in the same command line, for compatibility sake; default to us428 mode, of course. - New BANK switching allows for mapping to a maximum of 32 (!) logical channel-tracks. This introduces effective BANK L/R button functionality. Under the default us428 mode it now offers a total of 4 switchable banks (or layers) for the available 8 fader-channels; while in the new us224 mode, one can switch across 8 banks of 4 fader-channels each. Each fader-channel maps sequentially (0-31) to a logical track in your DAW, when connected in a MMC closed-loop. This only applies when not in INPUT MONITOR mode. - SELECT, REC, MUTE and SOLO state LEDs/buttons/channel functionality are now split into INPUT MONITOR and BANK modes, so that each bank (layer) has its own state. INPUT MONITOR mode gets its own independent state, which is the only that affects the audio interface channel signal volume (via respective faders) through the internal hardware mixer -- nb. this special mode deals exclusively to channel/faders 0 and 1 (A/B) and eventually to 2 and 3 (C/D) which are only available on the US-428 and made accessible through modprobe'ing snd-usb-usx2y with nrpacks=1 and thus made usable via the special hwdep "rawusb" interface mode (ie. hw:N,2). - The new track-channel mapping gets effectively signaled through correspondent but rather experimental MMC MASKED WRITE sub-commands for RECORD, MUTE and SOLO arming. It is important to note that this late SOLO sub-command is just some MMC implementation mockup of mine, as I believe there's no support whatsoever for just that from the official MIDI MMC RP-013 document (which I don't even have access to date:) However, I've been prototyping around with this, to my own amusement and home-brew audio/MIDI sequencer, qtractor: http://qtractor.sourceforge.net - NULL fader switch LED is now switchable on/off, but not actually of any usefulness at this time ;) I have tried to maintain all previous functionality as it were. Of course I only tested this new stuff over my own US-224, for which it surely needs the '-m us224' command-line option. This is also proposedto be specified in a correspondent udev rule, for all this to work correctly OOTB for the US-224 at least. US-428 owners don't need to bother ;) From: Rui Nuno Capela <rncbc@rncbc.org> |
