Set the other voice's Level to -80 to mute it.For a drop of two semitones set one voice to -2.Put a Pitch block in series at the start of the grid.Setup both blocks to Engage at the same time. Set it up with a Min frequency of 20,000 Hz, and a Max of 1000 Hz. Use it to cut the increasing high-end as the pitch is raised. Attach the same controller that you are using for the Whammy control to the 'Frequency' parameter in the Filter block. Try adding a Filter block right after the Pitch/Whammy block. These things were designed to be inexpensive. Higher sampling rates mean more processing power which means more expensive DSP. This limits the frequency response to 5K. I would venture to guess that the pedal sample rate is low, like maybe 11 kHz. Tip: increase the Scale parameter in the modifier menu a little to create some "flat" space at the top, so the octave arrives earlier and stays put.ĭecrease the max frequency of the pitch-shifted voice to 5 kHz, or even much lower (like 2 kHz), to make it less "digital" and less thin. It's demonstrated as part of the factory preset "JS410" (firmware Cygnus 16.00 and later). You can engage a Whammy on the fly without using Auto-Engage ("Golden Whammy", idea, ). Use Auto-Engage in the modifier menu to automatically engage the Pitch block. Use the Classic Whammy pitch type, and attach a pedal as an External controller to the Control parameter. Each detuner can feed back to itself and/or the other detuner. This type is comprised of two detuners with delay up to 2.0 seconds. The Multitap Delay block in firmware Ares and later is also capable of multi-voice detuning.įirmware 19.03 for the Axe-Fx III added a Dual Detune Delay type. Try running a Chorus block before or after the Pitch block for a more intense effect.īeware of Phase cancellation when running mono.įirmware Ares and later has two Detune modes: Pan the voices for a wide stereo effect.Put the block after the Amp block but before the stereo Cab block.Detune up and down the same amount, between +/-5 and +/-10.Van Halen's sound on the Balance album is well-known example of stereo pitch detuning. Pitch detuning is a great alternative to a chorus, without the "swirl" associated with 80's chorus tone. The Octave Divider sounds slightly like a synth, where a fixed harmony adds identical lower or higher harmony notes at fixed intervals. Pitch block: fixed shifted pitch, 1 octave down.The devices offer several ways to create an Octaver effect (octave down): Note that Quad Chromatic doesn’t have Feedback parameters.įirmware Ares and later replaces the Intelligent Harmony mode with: Wikipedia: Pitch shifting Chromatic: Dual / Quadįirmware Ares and later replaces the Fixed Harmony mode with: More explanation about diatonic and chromatic harmonies and custom scales Pitch types in the Axe-Fx III, FM9 and FM3: There simply isn't enough horsepower to run the Axe-Fx III pitch detector without sacrificing the number of simultaneous effects. The pitch detector still isn't up to Axe-Fx III standards but it still works well. Pitch shifters based on solution i fail in both tests.The pitch block was updated in 5.xx. And thus, a good pitch shifter shouldn't be able to change the pitch of white noise. And about white noise? In theory, you can't change pitch of white noise (unless stretch_factor * samplerate come into the hearing range). A good pitch shifter will keep the sine wave as a sine wave and only changes its frequency. If I test pitch shifting algorithms, I always take along a sine wave and a white noise as input signals. Solution i may result in serious quality problems, especially with synthesizers. There are two major approaches to solve these problems: Problem B: if the stretch factor is different from 1.0, direct combination of the grains will result in a hard jump. This means you have to fill the gaps with a copy of the grain. Problem A: If the stretch factor is lower than 1.0 (pitch up), you will get gaps. Step 2: time-stretch the grains from step 1. Step 1: granulize (= cut the input signal stream into blocks of something like samplerate / lower_frequency_limit samples The majority of pitch shifters use a granular approach: I guess Michael was looking for an algorithm (although he asked for a plugin).
