Who uses pitch shifters and or delays to create melody lines?
If so what do you use and some general setups/hints
Thanks 😊

Midi Echo is EXCELLENT for both pitching and delay because the echoes are midi, the sound is super pure and clean.
Indeed. This is one of my favorite techniques. I find it works best with drones or sounds with repetitive cycles as the source material.
For instance, I like to take apps like Fundamental, or Branches, which can create rich, unique drones, then split that out to 3 or 4 (or more) pitch shifters in parallel. This then creates 4 drones. To tame the chaos I'll throw an envelope / amp after the pitch shifter. This allows me to sequence each pitch shifter individually by triggering the envelopes at different times.
If the audio is cyclic, I''ll often put a static delay (no feedback or repeats) either before or after the pitch shifts channels. This create interesting rhythms, because a little phrase from the 'main' audio source gets played in the pitch shifter lets say 2 beats later. This can create a kind of push/pull type of feeling depending on the audio used. A favorite use of this technique for me is with talk radio. I'll take a talk radio segment, split it to 2 channels, delay one channel, then put them through their own amp envelopes. By alternating sequencing 1 (no delay) then the other (with delay) it create that push pull feeling. I set the envelope to be short and snappy, turning it into a hat / percussive sound.
If you have a drone going in a loop, simply splitting that into 3 pitch shifters will allow you to create baselines, and melodies, all from a single source. Changes to the source make changes to the melody and bass. When each is put under a static delay, those changes occur one ofter the other in time. My favorite environment to do these experiments in is Drambo. You can add as many delays (no repeats) and pitch shifters as you need. I have projects with 24 pitch shifters. I Would never want to manage that with AUv3's like Dischord 4 in Aum (24 instances of that may very well crash your project)
Anyway, I made this little demo to illustrate some of the techniques above (nothing amazing, just played around after reading the thread). The main sound source is Branches, which is just droning. There are 3 pitch shifters, their pitch shift amount is p-locked by scene changes. I have an alternating talk show percussive pattern with a couple instances of Radio Unit.
Would love to discuss more techniques involving pitch shifters and delay!
A few AUs which are useful in this context as well:
iVCS3 Envelope.
-This is the simplest MIDI TRIGGERABLE amp envelope AUv3. Surprisingly difficult to find such a basic utility. This is a great option to gate your pitch shifted drones, as you can sequence this effect by midi. Doesn't matter what note you send it, just press a note, and the envelope/gate opens. You can also set it to automatically cycle/loop.
iPulsaret
-iPulsaret has a live input buffer. The buffer is basically a delay. When the audio goes through the granulator you have the ability to pitch shift it. If you put this on a Bus Send you’ll have a delayed and pitched variety of your sound.
SpaceCraft
-Really smooth granular app. Concept is basically similar to iPulsaret. There's an 'infinite mode' which allows you to process live audio, including granular pitch shifting, and envelope and pitch sequencing to get those nice lil melodies.
Scatterbrain
-I don’t use it as often as I used to, but it will split your audio into up to 4 outputs, over 8 steps. This creates little enveloped segments of sound, when multi-bussed out can then be pitch shifted. Say you have drone at C4. You can bus it out 4 times, pitch one down to c3, and make the others E4, G4, and B4 to make a major 7th to play with.
Spectrum Effects - Granular
-this is just a decent pitch shifter, I think it has a buffer in it also, so you can use that to also introduce delay. Would need to put an envelope after that.
Virsyn - Bandshift
-the smoothest pitch shifter I’ve heard on IOS. Good if you want less artifacts on your sound, but not as immediate as a simple shifter like the module found in Drambo.
Great Post @aleyas
@aleyas Your hint at BandShift inspired me to try something new...
😁
@rs2000 nice idea! modulating/shifting the individual bands? Kinda sounds like R2D2 singing the blues.
😅 Yeah!
I’ve ridden the clock offset control in FieldScaper a good few times. On droney monotone samples it can be pretty musical.
