IFEA - Shifter
Key Features
- Real-time FFT pitch shifting handles subtle transposition and more obvious sound design moves.
- Dry/wet blending lets the shifted signal sit in parallel with the original source.
- Focused controls keep the workflow quick for live sets, resampling, and sound-design chains.
- Works as a Max for Live audio effect inside Ableton Live.
- Useful on vocals, instruments, drum loops, and other incoming audio sources.
- Distributed through the developer's Patreon post as an attached .amxd device.
Description
IFEA - Shifter is a Max for Live audio effect from iFeature and Phace that performs real-time FFT pitch shifting inside Ableton Live. It is built for moving incoming audio up or down while keeping a simple performance workflow around the core shift amount and blend control.
The device is intentionally focused: pitch movement, dry/wet mixing, and FFT processing are the main tools rather than a large modulation or harmony system. That makes it useful when you want quick octave moves, subtle detuning, or more extreme warped textures on vocals, instruments, drums, and resampled loops.
Because it is a Max for Live device, the practical audience is Ableton Live users who already work with M4L devices and want a lightweight pitch effect without leaving the Live set. The Max for Live listing documents Live 12.1.5 and Max 8.6.4 as the versions used, while the Patreon post remains the developer-controlled page with the current attachment.
It is best treated as a creative sound design shifter rather than a full vocal production suite. For formant shaping, MIDI-controlled vocal melodies, or multi-voice harmony, the paid alternatives below are deeper tools.

Frequently Asked Questions
Is IFEA - Shifter a VST plugin?
No. It is a Max for Live device, so it runs inside Ableton Live with Max for Live rather than loading as a VST, AU, or AAX plugin in any DAW.
What does the device do?
It performs real-time FFT pitch shifting on incoming audio. The official feature list centers on pitch shifting, dry/wet blend control, and flexible use on vocals, instruments, drum loops, and creative sound design material.
Does it include formant control or vocal harmony features?
The public feature list does not mention formant shifting, MIDI harmony, or multi-voice vocal processing. Treat it as a focused pitch shifter rather than a full vocal manipulation suite.
Which Ableton and Max versions were used by the developer?
The Max for Live listing states Live 12.1.5 and Max 8.6.4. Those are the documented build versions, not a full compatibility guarantee for every older Live setup.
