Track strips with independent speeds and lengths

Here’s a topic from March 2012 that might be of interest to you, as it somewhat applies to your description above:

http://forum.renoise…d-group-tracks/

Basically if we could load up tabbed projects containing clips/songs, all of them being routed to a main output and master section, things could also be configured in a way so that each tabbed project had their own “pattern arranger” independent of each other, including tempo changes, pattern lengths, etc.

Also see the initial topic back in 2011 on running multiple Renoise instances together (tabbed/multiple songs, Rewire-like Renoise protocol, or in a new third arranger wrapper): http://forum.renoise…oises-renoises/
