> anyone have any idea how to do this?
The first approach that comes to my mind and that I would try is:
- use [env~] (or anything similar) to measure the amplitude of the signal
- start a [timer] when you start recording
- set TWO thresholds: one high threshold to detect when the "note" has
begun (attack) and a low threshold to detect that it has finished.
- Only after the signal amplitude has become greater than the HIGH
threshold _and_ when it becomes again lower than the LOW threshold, then
you fire the right inlet of the [timer] to measure the time passed since
the beginning: you multiply by the sampling rate and you obtain the size.
That is, you have to emulate the behaviour of a [threshold~] object and
use its "rest" bang (see threshold help patch).
Since you're probably gonna use [env~] you cannot actually use
[threshold~] but it's very easy to emulate its behaviour (at least
simplified as described here which is enough for this purpose).
- Be sure your patch produces the size only once within the recording
time (which is predetermined if i understood correctly). If you want to
allow two or more fff staccato notes to be recorded in one "sample",
then take the _last_ occurrence of the abovedescribed condition (one
transition up the high threshold + one transition below the lower
threshold); if you want to allow only one fff staccato note to be played
(and suppose so), then take the _first_ occurrence.
This is certainly a very simple and probably a bit naif approach, but I
would give it at least a try before diving into something more complicated.
Hope it helped
