duration/analysis synth

[mattschumaker]

As per @EdmundCampion

Please create a "testing synth" in Max/MSP to meet the criteria listed below. The synth will be immediately useful to play files from the CNMAT-OM library but may also have broader application in Production or otherwise tbd.

The basic synth criteria are:

--receives midi files and, in particular, processes midi onset, midi-off and note-durations of all notes

--adjustable tempo

--if possible, there could also be a control scheme that controls the sound output over a time value provided by the user, e.g. "fit all events/notes within 20-seconds...."

--separates the attack portion from the rest of the envelope for each note

--for the attack portion, the synth should have clear, percussive attacks and:
--to start, Karplus-Strong might be implemented for this section
--eventually, we might want to create a library of excitations to use that would be sample-based

--for the envelope after the attack:
--this should be shape-able by the user, perhaps with a bpf. For instance, being able to fade amplitude in and out over the course of the note.
--all envelopes should compress or expand in order to conform to the current tempo or other timing control

(--eventually, we may want the potential to assign different attack and sustain timbres to the different voices in the midi file or even potentially according to the duration of a given note.)

Trying to figure out where this should live.

I might suggest /patchers/MIDI, but it could also live in /patchers/basic_DSP or /patchers/synthesis.

thoughts?
simple_karplus-strong and reso-string~ both live in /patchers/synthesis. That might be the best fit.

/patchers/synthesis

add a timbre assignment to the karplus voice - maybe brightness etc
