Envelope sequencer |
|
|
Thought of this when Inventor mentioned his thoughts about a hardware sequencer in another thread - it brought back some ideas I've had before.
It's a cross between an envelope and a sequencer. Check the attached sketch for an overview how it works. I've also attached small sample where the sequencer drives the pitch of a single oscillator.
The idea is that there are 16 points on the envelope. For each point, you can configure what voltage (or control value) it represents, and how it will take the envelope to get there from the previous point. In my example in the sketch this is done alternately on the knobs of my BCR2000 - the top left knob controls the first level, the one to the left of it controls the time to that level, the knob to the left of that controls the next level and so on.
If you leave it like that, the envelope just goes round and round. You can synchronize it to MIDI notes though - when a note comes in between note 60 (C4) through note 75 (D#5), the envelope will immediately jump to the point that corresponds to the distance from C4, i.e. a C4 will jump to the start of the evelope, a C#4 will jump to the second point and so on. The curve at the bottom of the sketch illustrates this.
The ChucK app may be modified pretty easily to send MIDI or OSC instead of control voltages, which only work on DC-coupled audio interfaces (or is it the other way round?). You could also have it controlled by something else like OSC or a software GUI, and you could change the MIDI note reset to some other kind of event like OSC, CV, joystick tweak or whatever.
Les was wondering in his thread whether that kind of sequencer exists in hardware, I'm wondering the same for this one. It's a very simple thing, but there could be a lot of usage for it (at least I feel an urge to try out some experiments of my own with it).
Thoughts?

Yes, it is not an allowed extension currently, if that is bad I can change it ... _________________ Jan

Nah, they're spacegobblers anyway, and it's easy enough to convert to mp3.
