    First of all, thanks for making this software available for linux, this and the good sound quality made me purchase it.

    The pitch shifter effect can't be used as de-tune on the fly, I've tested in in linux and windows and the latency is big and produces some artifacts (maybe only because of latency).
    I've used guitarix de-tune in the same setup and in the "high quality" option the latency is also bigget than usable on the fly but it has a "low quality" (or maybe medium-quality) which works perfect at least with distortion. You could look at the code here https://sourceforge.net/p/guitarix/git/ci/master/tree/trunk/src/LV2/gx_detune.lv2/

    I could make this work using tracking ~20[ms]. 15 also works but 10 doesn't in my case. The default of 85 is too much, I didn't realize it was ms.

    I would love to hear how you made this work, because it is just garbage for me :( Guitarix is my go-to for pitch shift. This is what keeps me from going all ToneLib. I also have Graillon, which works well *but* it doesn't cover the full spectrum. It's designed for voice, and this doesn't match my use case.

    Hello,

    I think the tuner in Tonelib works poorly. I always use Guitarix for this.

    @Summers I use the pitch shifter for de-tune my guitar 1, 2 or 3 semitones. Not sure what you mean with petrucci (I know it's DT guitarist). Maybe you mean a "Harmonizer" in which you put the scale and the interval and it harmonize in for example 3rds in minor harmonic scale. I don't think tonelib has that (nice to have), I used it in my pod hd and it works pretty well for the end of "hold the line" solo from toto.

    @tonelibwlk this are the seting for 1 semitone (Eb) down I use (for 2 semitones pitch should be -2):
    Effect: "PitchShift" (Modulation / Sfx), active - "yes"
    {
    "Pitch" = -1
    "Fine" = 0
    "Tracking" = 15
    "Direct" = 0
    "Effect" = 100
    }
    Tracing between 15~25 is what make it work to me. I'm also using 4.7.7 now, not sure if this setting worked before since this is the first time I could make it work, and I tried a loooot before (but maybe never tried this setting)
    Also in jack I have 8ms latency, maybe that's important too.

    @hmollercl Thanks, I'll give those settings a try. My use case is one octave up, so perhaps things work better at only a couple of semitones. I'm more interested in quality than latency. I'm not trying to do anything live. Thanks!

    @tonelibwlk if you one octave intervals there is a pedall called octave, I assume it should work better in this case.

    @hmollercl thanks, but unfortunately that only does octaves down :(

    Thanks for your reply. i was talking about "Neural Dsp - John Petrucci" plugin, and how its pitch shifter works (built-in on the fly)!
