I haven't thought about it much but I view the
hardware mixerstrip level fader as being synonymous
with the "trim" on a traditional mixer. If an external
device generates test tone 0db then use hardware mixer
to adjust relative hardware port to 0db.
Subsequently a DAW mixer is configured to route N
sources to the relative hardware port which is
configured to something that's thought to be 0db.
Ultimately enabling many signals of various decibal
levels to be routed through one or more hardware ports
that have constant gain.

The HDSP mixer (TotalMix) is an amazing little tool,
allowing you to
control levels/signal path to and from any arbitrary
(or all
simultaneously) inputs, outputs, etc.
But why not have this functionality for every ALSA
supported card via a
JACK totalmix client based on Thomas' hdspmixer
code? Mixer strips would represent available hardware
routes by default, but
strips could be added and subtracted as new clients
are started,
Assuming that I'm correct about the intended purpose
of hardware mixers, then your idea mixes client routes
into a common interface with hardware ports. I'm
thinking that on a basic and simple level the problem
with this is demonstrated when you begin to use the
hardware mixer to adjust level. For example, if more
than one application routes playback to hardware
capture ports 1,2 then adjusting the hardware capture
1,2 port level will cause all application playback
sources to be adjusted. Of course that's a management
problem that a DAW mixer is designed to control.
Anyway, I just quickly read your letter and probably
missed your point entirely. Hope I didn't create extra
confusion for anyone but me--as if it's possible to
prevent myself from being confused. :)
ron
just
like Qjackconnect but with live faders (or scopes,
jellyfish etc) like
hdspmixer. With JACK, meterbridge, and hdspmixer,
aren't we most of
the way there?
This might also solve previous complaints by Mark
and others (the DJ
crowd) of pops and clicks when clients connect to
JACK. Levels for
each client could simply be raised in the JACK
totalmix.
Anyone working on such a thing?
