is there any chance to see an improvement in the pitch shifting algorithm, so that we dont hear any latency. Or do you think you will need more processing power for that?
you need to think about what is actually happening when pitch shifting...
the very basics:
the played pitch has to be 'listened to' so that the note sounding can be determined
then the shifter has to throw some math and this note to figure out what it's pitch should be changed to with respect to your pitch settings
the pitch shifter then has to recreate the audio at the new pitch
all this takes time.. especially the "listen to and detect the pitch of the ingress audio" part
hex pup guitars with the VG-99 / GR-55 seem to do this stuff a little better because it's a slightly different technology
but the same fundamental processes apply... listen and determine the pitch... change it...
but even then there is still a lag.. just a very slightly smaller one..
when you use an octave divider, the same processes are at work...
but most often you'd use the octaver in conjunction with you unprocessed signal..
your unprocessed signal happens 'immediately' and the octaved signal will be a tiny bit late...
but you tend not to notice it so much because the delay is masked by the unprocessed dry signal
the only way to get very high quality pitch shifting is not to do it in real time
which is perfect in the studio when mending vocals and stuff.... but no good when you're stood up there in front of all them peoples...
seriously
if you really want perfect responce and tone... get more guitars and set them up and tune them differently..
I have a 7-string tuned concert
6-strings tuned concert, Eb standard, D standard and open G
not the answer you're after I know... but it's the only one that is 100% assured..
