[Traverso-devel] Traverso-Routing etc

[Niklas Klügel]

Hey!

I've been looking through the Traverso code lately and I am planning to 
incorporate signal/control-routing to traverso using CLAM [1].
Since I am working on that mainly because I'd need it for myself I am 
not exactly sure if you are okay with the imeplementation I am working 
on. The basic concept/proposal is:
1) Implement a NetworkPlayer that uses Traverso's 
AudioDevice/audio-backend so _external_ audio will be routed into and out of
the CLAM-Network
2) Implement as CLAM-Processing: either Traverso's Track-Class (so 
Tracks are Audio-Generators in the CLAM Network) or AudioProcessingItem 
(the advantage would be that you could implement a different 
NetworkPlayer to do Offline-Processing using
arbitrary CLAM-Networks on i.e. AudioClips -> commands for certain 
offline f/x such as preverb etc.).
3) Implement a Master-Bus as CLAM-Audio-Sink to return the processed 
audio to Traverso's internals (advance: multichannel mixdown possible 
without changing much of the Network's topology e.g. stereo downmix to 
5.1 downmix (especially handy if you would want to use CLAM's spatial 
audio processors)).

All in all: do all the mixing within the CLAM Network. This allows for 
the most flexible routing, including side-chaining and return channels 
with a certain degree of recursion. In order to do proper 
mixer-automation, arbitrary control-curves would be needed; those would 
then be output to a control port of the related Track-Object in the 
CLAM-Network (possibly the toughest part).
The gain from that is that it would make way for automating anything 
within the CLAM-network, such as f/x chains etc. and finally would lead 
to a very robust way to add "midi"/note-editing afterwards.

I am currently working on 1). I am not so eager to do coding so it might 
take a while regarding whether I am busy with real-life or doing music, 
but if you guys are interested in the outcome I'll try to comply with 
the coding-style that you guys use and not make just a quick hack.

Take care!
Niklas
