[linux-audio-dev] Sequencer Concept

Hi! I have been thinking about how an advanced sequencer could look and work over and over again and now finaly managed to come up with one consistent concept that i would like to present here now. A mockup to illustrate the following explainations: http://wrstud.uni-wuppertal.de/~ka0394/forum/sequencer_05.png The basic idea is to have nested containers to be arranged verticaly and horizontaly. All information is tied to or contained in these containers. As the horizontal axis stands for time, i needed to express the nesting only verticaly (plus color), so that's what the round corners and the empty bottoms of the containers are for. Maybe it helps when you think on Lisp and paranthesis, only vertcaly. On the mockup the big white container defines absolute time (min/sec) and the context for playback control (only one play position inside thsi container (for each user)). Several of them could exist in parallel, all with their own playback control. The next, yellow container defines the meter (the ruler) 4/4, followed by a tempo track set to 120 BPM. The blue container is an audio container. These can take others of their kind, audio inputs and outputs and finaly audio clips. This one defines an "Out 1" and its send level and conatins 3 clips. Below it, the green container sets a 3/4 meter. Because it is inside the 4/4 container, the quarter notes match. If outside, it would have to have its own and independent tempo track. The last Container is for MIDI. It has IN and OUT as attributes. Alternatively these could be expressed on tracks like used for tempo, what would make them changeable inside the container. Every Container can be used as a pattern (instances). They could have a dropdown menu to swutch between different versions (/takes). I have some more ideas and details, but i think this should be enough for now! :) I have only basic and seldomly applied coding skills, and this doesn't look like a one man project anyway ... So I hope for interested developers ... or that at least this gives someone some inspiration. I would be happy to further develop my concepts of course (allthough my diploma in industrial design, same topic: sequencer takes priortiy for the next 3 months). --- Thorsten Wilms
