Perhaps you'd like to play around with Nama,[1] which does much of what you've asked for. It is lightweight, hackable, runs under JACK or ALSA, and you can start/stop the transport with the spacebar. :-) Ecasound does all the heavy lifting. To provide mixes for individual musicians, there is a feature called 'send buses'. When you create a send bus, every track in the Main (default) bus gets copied, and all their output gets sent to the destination (soundcard channel or JACK client) you specify. You would need to create a send bus for each performer. nama> add_send_bus_cooked Jostein 5 # sends to soundcard channel 5 # or 5,6 for a stereo signal In this example, the ordinary track 'drums' would become 'Jostein_drums'. You can adjust the level of each of the slave tracks in a send bus without affecting the original tracks. That's how each musician gets her own mix. nama> Jostein_drums vol - 5 There are two types of send buses: one sends the raw track input, the other sends the "cooked" (effects-processed) signals. Unlike ordinary sub-buses, send buses do not (currently) have a mix track. That was chosen to avoid the delay of an extra Ecasound loopback device in the network. To adjust the overall level in software you could do this: nama> for Jostein; vol + 3 which increases the volume by 3 db for each track in the Jostein bus. What we would have to hack up is some kind of playlist functionality. The backing tracks could live in a separate project, and could be linked in turn to a dummy track in the current project. I think that would be pretty easy (although it's always a bit of work when you have a new mode to switch in and out of.) If you were just monitoring your musicians, you'd need to get the live signals, but then disable recording to disk. nama> for Main; rec; rec_defeat Then you'd just have to reset the backing track to MON (which the above command would have toggled to REC.) nama> backing mon # note that the track name (if needed) always goes first If you now decide you want to record your musicians: nama> for Main; rec_enable If you want to play them all back: nama> for Main; mon # usually happens automatically after recording To disable all tracks of the send bus: nama> for Jostein; off That's how it goes. We try to follow the perlish philosophy of making easy things easy, hard things possible, and digesting (or swallowing whole) any other software or CS goodness that can help. :-) Regards, Joel 1. https://freeshell.de/~bolangi/cgi1/nama.cgi/00home.html https://github.com/bolangi/nama -- Joel Roth
