Any harmonizer examples?

[matmonster58]

I just found out about these boards and ill defiantly be building one as a dedicated reverb pedal. I'm kicking around the idea of building a pedalboard just for my fretless bass. I'd love to have a harmonizer pedal to get this type of sound at 4:15

I saw a pitch shifter in one of the git pages. I know that I can program this a Daisy Seed to do what I want it to, it'll just take me a little while to learn how. Are there any examples out there of how the pitch shifting sounds and how the tracking is?

While I think possible to achieve what you want, the pitch shifter I wrote/tested was primarily done with the intention of 1 or 2 semitones up/down to not need to retune. For that use, it tracks very well and sounds quite good IMO

The algorithm used for pitch shifting from the DaisySP library (using time delay essentially) requires a larger buffer (more samples) to sound good for a larger amount of pitch shifting (like 12 semitones = 1 octave). This leads to pretty unusable amounts of latency. I add more latency the more semitones away from 0 you go.

I have a wet blend and dont think it is really usable for anything like this.

I think this is the direction you would want to go https://forum.pedalpcb.com/threads/terrarium-polyphonic-octaves-code-demo.23453/

I think this is a fun project and worth exploring, but know that it can get quite a bit more involved than an analog pedal build if you dont have a patch/sample code/video of someone having already done exactly what you are looking for.

Also keep in mind, a true harmonizer is a bit more complicated than a pitch shifter. Shifting the pitch is only half of the puzzle.

You have to also detect the incoming note, compare that against the desired scale / mode, then shift the pitch by a calculated interval. The shift in semitones will be different depending on the note played and the scale we're playing "in harmony" with the input signal.

Simply shifting the pitch by a set number of semitones across the entire riff is not going to give the same sound as your clip.

I'm using the cycfi q library to do monophonic pitch detection for my synth pedal: https://forum.pedalpcb.com/threads/terrarium-synth-pedal-code-demo.22631/

I am waiting for Joel to release his new Hz algorithm!

Here is my frequency detector class also using BACF from the cycfi q library https://github.com/bkshepherd/Daisy...are/GuitarPedal/Util/frequency_detector_q.cpp

I had great results adding a https://gery.casiez.net/1euro/ filter on top of the detected frequency FWIW
