So what are in your view the main obstacles? I can image a concept based
a class called "channelstrip", which as you can guess represents an
audiochannelstrip handled by a channelstrip-handler. This handler also
masks the jack-backend, such that the user only need to initialize it
with the jack name like "TerminatorX outputs", number of threads for DSP
related stuff and thats it. The handler does all the stuff from
registering the jack callbacks to creating/destroying channelstrips and
busses. The controlparameters of each strip are given to the user by
boost::signal(2)s.
So in a nutshell the user only needs the class channelstrip and the
means to create/destroy instances thereof. The concept is cleanly
seperated from the other parts of the users application.
I've actually implemented this rough concept into TerminatorX and it's
working. tX now has full stereo outputs of each turntable, no matter if
the sample on the turntable is mono or stereo (this is missing in the
current release, making it hard for many people to use tX). It should be
conceptually easy to export this functuality into an external library.

Hi, I'm messing arround with the source of
TerminatorX. As it seems, tX
needs a total rewright of the mixer and the audio backend.
Since many programs (Ardour, Qtracktor) have built mixers, I was wondering
from which project I could 'borrow' the mixer component.
I need a mixermodel which is strictly C++, which idealy has jack support
built in, possibly multithreaded, GUI-Independant and easy to handle.
I started to wright my own mixermodel, but then I thought how stupid it is
to reinvent the wheel. It would really be nice something like a libmixer
with jack, lv2, ladspa and VST support.
i've heard people talk about this idea of an "audioengine" for years.
i've never seen it. the design inside ardour is at once both extremely
general and also very application specific. i have a hard time
imagining anything else.
