I don't want to offend anyone.
It is probably a sign of today's times that subjects related to mathematics, programming and algorithms are expressed by people who have no clue about it. They imagine how it should work and believe that they are right even without reading even one scientific paper on the subject.
Yep. Hence there is always latency when applying digital pitch shifting. However, I stand by my assertion that input pitch recognition is not needed for a chromatic pitch shifter. Only an envelope detector is required which requires less samples of the digitized waveform then a pitch detector.
I speculate that the harmonic pitch shifter, on the other hand, requires both an envelope detector and a frequency detector. Both pitch shifters will then use some kind of algorithm similar to the one you linked.
Edit... After considering this a little more, I'm definitely minimizing the complexity of the process. For any pitch shifting, some sort of frequency analysis most likely takes place to provide a realistic sounding shift. I've talked myself out of this argument (don't tell my wife!)
Unfortunately, that's not how pitch shift works.
As far as I know you can't do what you are suggesting with a digital pitch shift. The math is way above my head but hear are a few papers that explain it. One relates to real time pitch transpose on guitar (less than 50ms). Another the different ways of converting pitch and what constitutes low latency (less than 20ms) while the last on talks about midi pitch detection but the sampling of the pitch is the same whether using it for a transpose algorithm or to convert to a midi note value and confirms the MINIMUM latency for a low E on guitar is 12ms plus the time taken to run the algorythm.
pitch shifting is not a simple thing to do.
I'm not convinced that the latency gets any greater the further you transpose from the original note. I expect it is the changes in formants and digital artifacts that degrade the sound and make us think we are experiencing latency but I could be wrong.
You are correct that there will always be a processing latency in any digital pitch shifting algorithm. However, the latency for a chromatic pitch shifter will/should be less than a diatonic (harmonic) pitch shifter as the later must detect the input pitch to apply the correct shift interval. I haven't investigated myself, but I would assume that the transpose option in rig settings will have less latency than the chromatic pitch shifter. I'll have to investigate this evening.
as i said: it just needs to think: everything that comes in, i will let out through the -100Cents door.
it does not need to know an exact note. just put every signal 100 cents(for example) down.
the digitech drop at least has no feelable latency when going down 1 or 2 halfsteps, it gets a tiny little washy when going 3 steps down. i wouldn't use it any lower.
I'm not sure how it's done in the Kemper, but you are correct that a direct pitch shift (i.e. minus 1 half step) should have very little latency because it doesn't need to detect the input pitch. However, if you are using an intelligent pitch shifter (i.e. shifting withing the scale of a key) then there will be more latency as the algorithm must detect the pitch before it can apply the appropriate shift to stay within the desired scale.
I'm having issues dragging effects into my presets library. When I try to drag a treble booster (for example) into my local preset library I get an error saying, "Import has failed. Rig Manager didn't find any suitable files to import. This happens if the items are unknown or damaged."
7.0.8 solved the issue. Thanks!
Sorry for the double post. I originally posted this in the OS7 public beta discussion, but realize it's better suited here.
I'm running 22.214.171.12442B and RM 126.96.36.19949. I'm having an issue where when I preview performances from RM the amps/effects don't change. For example, when I change perfrormances (by double clicking in RM) the number of active slots works (i.e. first performance has 5 slots while the next performance has 3), but the contents of the slots doesn't change. I have double checked that nothing is locked. However, after I copy a performance to my Kemper it works as expected. Is anyone else experiencing this?
I'm running 188.8.131.5242B and RM 184.108.40.20649. I'm having an issue where when I preview performances from RM the amps/effects don't change. I have double checked that nothing is locked. However, after I copy a performance to my Kemper it works as expected. Is anyone else experiencing this?
Thanks! I'll try them out and report back
Has anyone tried these yet?
