So what do you cats think of the current state of pitch shifting?

It's been an area that I sort of gave up on for a number of years as I wasn't that happy with it at the time.

I've used the HOG, but as I found it functions almost more as a quasi-synthesizer than a pitch shifter (in that it doesn't really preserve much of the timbre...I mean you don't go "oh, that sounds like the input just at pitch x") -- that particular implementation isn't what I'm tinking about

 

how do you guys find the current crop of stuff in terms of preserving timbre/character of the input?

how are the compact pedals in that regard? (thinking about toying with them again...The last time was like very very late 80s early 90s..around the time the first Boss one's started coming out, but the app has some space sensitivities)

hmmm, thinking about toying around with em again, but also just curious how they are coming along.

I havent looked at the current processing algs, so how the methods have improved and where the trade-off-are sort of intrigues me
like, with the HOG, I suspect that they are time streetching/compressing in sort of static, arbitrary chunks, which could account for the wy it (artisically) brutalizes the timbre but could also account for the lack of "tracking" glitches (no need to work through, say, a fourier analysis to try to "stretch" the waves and keep waveshape/harmonic distribution, but which could also "glitch")

I've played with some of the earlier vers, but not the 4

Do you find it holds the timbre decently well through the process?

(one concern is, from both the practical app and just state of the art is I'm not really coming from a rock guitar orientation so stuff like overdrive/clipping distortion covering up artifacts isnt really in the scope of my {censored})

It's pretty good!


Uh, not so much in pedal form I guess. If the HOG/POG doesn't satisfy you, probably nothing will. It seems like I read somewhere that the POG does do fast fourier transforms though.
:idk:



thanks! it may very well use FFT (my guess was just based on how much it really tweaks the timbre, I suspected that what I was hearing were hard edges of time blocks kind of reminded me of artifacs I've heard in "dumb" time stretching schemes, but it might not be the case...so thanks for that as Im kind of academically interested in where they are now too)

yeah, I mean the hog/pog as an artistic tool I think are nifty...but as pitch shifters...I though they leave a lot to be desired from a 'trnsparancy' sort of perspective

no I definitely wouldnt consider it state of the art, its glitchy and digital in a bad way, and those are both reasons why i like it haha:D

probably I suppose

(use to have a soundart Chameleon, that was a lot of fun /c you could directly access the DSP, but DSP is NOT my forte -- so it was a lot of basically grabbing code chunks ala a script kiddie ;) )

eh, thanks for the honest heads up on the state of affairs -- it's really just mor a "play with it" thing
for the practical side, if it aint there yet, it aint there yet

Buy an eclipse and be done with it.

 

 

+1. At the end of the day if you're enough of an audiophile to be thinking about FFT and artifacts, then a pedal shifter probably won't do it for you.

y know, that's one thing about that whole "expression" series digitech had...it sure seemed like a lot of em would have benefitted from a couple of extra controls to get em dailed in

 

 

how so? That expression factory looks really fun to me. Is there anything I should be warned about?

The way to get a better compact pedal pitch-shifter is for someone to market a platform for running software on a compact pedal... I'm working on some ideas of my own, but it will be years (at least 3) before I have a fully-working thing. There are already efforts along this path, but they are VERY expensive or very limited (the Tonecore dev kit is kinda what I'm talking about, but more powerful). The technology exists to run a software DSP in that size package, but it has to be "perfected" to an inexpensive product that can easily and reliably run off of 9v and never crash or anything.

 

It's definitely a path that I will be playing with a lot... I'm majoring in Electrical Engineering and minoring in a brand new minor: musical instrument engineering, which includes effects pedals! A good pitch shifter is definitely something I'm after, because I have been disappointed with everythign I've tried, and it IS possible to develop somethign better, and also something much cheaper than the HOG.

I was thinking more of the "XP" stuff - the space station, the reverberator, the 100 whammy

 

they basically had patch change and the treadle

Dude thats awesome, for the first time I have a slight regret choosing VT over UVa (assuming CVille in your sig means you go to UVA). Im also an EE major but theres so much bull{censored} to wade through first that I havent gotten to anything worthwhile yet and Im taking next fall off to do my own thing

YOU GO TO TUFTS!

i know this because i googled 'musical instrument engineering' because it sounds like a much cooler minor than my econ minor. we have to hang out now slash i must see what you can think of pedal-wise.

{censored} i wish bu had that :cry:

I actually go to Tufts which is outside Boston. I know people at both UVa and Tech, though. I grew up in the Ville.

Don't despair, you can also figure out a lot of this stuff on your own if you're dedicated to it
