Create Halls to perform by interacting with loops from different rooms

[xavierfav]

It would be nice to have another concept than the rooms. It could be some kind of meta rooms which would allow to sequence different room loops and thus enabling live performances.

For instance, a hall could allow to interract with loops from different rooms. In a hall, a room sequencer, sequencer track pads cannot be edited. Instead, we can mix tracks from the different rooms.
All the tracks from a room could be grouped in different new meta tracks, and allow different functionalities:

• display track names
• start/stop track (loop sync)
• track gain, send to return Add reverb & delay return tracks #52, solo/mute
• main track group gain, solo/mute, tempo

A user could live sequence tracks from different sequencer rooms & presets to make a performance.
The interface would present two main parts:

• the grouped tracks with the functionalities listed above.
• a section for the one a user drag and drop available sequencer rooms & presets.

It is not yet clear if making collaborative halls would be a hard task. Maybe as a start, these halls could be be _private rooms_ #48 that are not shared from the server.
