Pd should not crash. if you experience a crash, you should post a
(minimal) patch that exposes the problem, so it can be fixed.

well, it became unresponsive. but this i think was because i had a toggle going into a bang, which was sending to a delay, which was trying to untoggle the toggle, which would then send out a bang. so it was my fault really, endless feedback loops causing unresponsiveness and then me not being able to remove a specific segment of it to stop it from feedbacking/being unresponsive. so no point really trying to fix, right? :)
 
anyhow, [phasor~] and [metro] both repeat, so they seem to be the wrong
choices for a one-shot operation, instead of [line~] and [delay].

also i don't understand why you would want to dump the array into
another array in order to record it. sending the audio to a [writesf~]
directly should be enough.

Thing is, the array (let's call it plom) is played at like 0.0017 speed or more, so to capture what "plom" sounds like when pitched down, i thought i'd have to write it into an array, and save that array safely. maybe i've misunderstood, but i was able to then capture it  into an array and write that array. i was just hoping to do it in a snappier way rather than having to have a metro toggled on, until it felt like the array was full, and then stop the metronome, and then manually tap on save-sample.

so far i'm quite happy with how the script goes, it's very simplistic, just two oscillators, a delay, a method of sampling the oscillators+delay result into an array (plom), then a midicontroller knob to control the playback of the array (plom) between -2 and 2. now i'm just trying to get the happy accidents (plom pitched down) into a randomly named filename (or maybe a date/time named filename) so that i can retain them, instead of losing them everytime pure data is booted.

after numerous mistakes, i was able to (i think) get this to work somehow. i'm not sure if foo = plom, but i put tabread4~ and array size as plom (as that's the original material). i am able to now feed the phasor~ playback speed into the [/ 0.016666] -2nd port, and if i tap on start, and wait a while and tap on stop, i get a type of sound. it's not in the same pitch as what i'm hearing, so what i hear isn't quite what i get, but it's definitely a step in the right direction. i took a screenshot of what i ended up with, if that helps.

i'm kind of halfway there, thanks to you! all i gotta do is get it to actually be at the same pitch and work, and figure out if i should just keep with 0.01666666 that you suggested, or have that be changed by the playback speed (that i'm using to feed to phasor~.. 

and the 2nd step is to get the date-time writing to the filename and somehow stash the long-ish path somewhere. phew.
i never thought i'd get this far!
