went over the source code with a programmer friend. made a couple guesses but didn't really get anywhere. I don't really think I'll be able to get any definitive answers unless it was coming straight from the designers/programmers. oh well!

I am not talking about FORMANT GET or SEE or GETSEE - those I understand.

My problem is trying to wrap my head around the exact differences between REPLACING, IMPOSING and VOCODING.

I have provided illustration for my experiment - through five different sounds. The 'source' sound, which is a strange drone produced by the BLUR process. The 'formant' sound, which is a clip of me speaking clearly. And then, the outputs for imposing, replacing, and vocoding the formant sound onto the source.

The formants were grabbed at the highest linear frequency-wise resolution.
The frequency domain is log scaled.

Could anyone try explaining these to me? I'm probably just way overthinking it, but I'm quite obsessed with trying to develop a comprehensive, rigorous understanding of these processes.

a majority of the processing in this was done with CDP (in Soundshaper) and arranged/edited in ableton live. some nice soundscapes in the first couple minutes from a party buzzer sample.

Ah! The warp marker! I've never actually played with it while manipulating MIDI clips! Live is always giving me pleasant surprises. Thanks a lot!

Hmm, maybe Ableton Live facilitates this and I just haven't figured it out, but in Live's piano roll, when you have a bunch of notes selected and you shrink/expand the end, it keeps all the notes in position and just alters their lengths. I will find out if I'm overlooking something. The JUCE idea is a good one though, thanks.

Does anyone know of a tool that can generate weird tuplets in a MIDI file? Obviously almost all DAWs/sequencers nowadays will support triplets, but I'm talking about any number of measure divisions, from quintuplets, to septuplets, etc. Been fixated on polyrhythm/polymeter stuff lately (5 against 7 has such a nice character) and manually doing the math and painstakingly sequencing out things like septuplets (with a good amount of trial and error) is quite tedious. Would just like something that generates basic midi files I can just import into live or something. Might just try making my own if nobody knows of anything like that.

lol. I feel so silly, I spent a good half hour obsessing over trying to figure out the single formula that would scale a normalized set of values (like breakpoint env values) to a specified min/max. I was overthinking the living christ out of it, then a friend pointed out it's literally just n*(max-min)+min. protip: don't drop out of high school. 
well. at least I can write myself a little script now

At least this got me to finally dive in a bit into the data editor. I really like it though! And through simple multiplication + adding on the value column, voila, what I wanted. I will suggest this though, Robert Fraser: I believe it would be very useful to add a scale Y values function to the "Scale" button on the T-V parameter window.

Some visual aid...

My idea: clicking "Scale" gives the user the option to scale X (time) or scale Y (vals), perhaps a little window like when you open Graph-Edit and it asks how you wish to scale. Scaling Y requires you enter min and max values (for Y to be scaled to.)

The data you see here is actually an example of what I mean: it was originally a brkpoint envelope file (.env) so of course the val column was originally scaled 0 - 1, as they all are.

I wanted to scale it from 0-1 to 2-50, so I multiplied the column by 48, then added 2. Ideally, I want to be able to just enter a min and max val and let the computer figure out the operations for me.

I see this as an important facility because it would open up great ease for utilizing envelopes in T-V params, which adds endless creative prospects to automating with envelopes.

I'll likely end up making my own little tool for it, because it does seem like a simple task. I'd just very much recommend making it part of Soundshaper, if only just to keep it all in the box!

(gonna be a little embarrassed if this is already a feature... but feel free to point it out to me if it is!!)

I definitely do a good amount of doc diving, but decided I may as well utilize this forum -

I think it'd be very useful to use envelopes as breakpoint files for parameters in various processes. I do know you can create an envelope breakpoint file, I've managed that - of course, the values are all 0 to 1. Is there any utility I dont know of (perhaps specifically in Soundshaper) which facilitates the scaling of the values in the second column? just setting the min val and the max val and perhaps some other parameters (linear or exponential interpolation, etc). if there is a solution to this I am overlooking I'd appreciate a point in the right direction, because man that'd be SUPER duper useful!

(it's probably in that data editor, isnt it? I've been meaning to tackle that thing, looks very accommodating)

Huzzah, that updated exe fixed it! I ended up moving CDP straight to C as recommended (C:\cdp) but that did not fix the error - I even installed it on a friend's computer (who also runs Windows 10 64-bit) and still got the same error (with the random quotation mark). But patching in the new exe, now it works just fine. thanks a lot, really been wanting to utilize this function.

oh thank you!! I totally overlooked that.

thanks a lot richard. (ah wait! broken link!)

excellent! color me interested! I use windows.
