Pitch Shifter

The Pitch Shifter module changes the pitch of the Audio signal using a classic delay-line pitch-shifting algorithm, offering Shift, Window and Spread controls.
Shift: Adjusts the pitch by up to 24 semitones in either direction.
Window: Sets the length of the overlapping segments used for pitch shifting, from 5 to 500 ms. Shorter windows respond more quickly, while longer windows generally sound smoother.
Spread: Detunes the left and right channels in opposite directions by up to 50 cents.

Frequency Shifter

Replaced the Stereo toggle with a bipolar Spread parameter.
Shift applies to both channels, while Spread offsets them in opposite directions: left uses Shift minus Spread and right uses Shift plus Spread.
Shift and Spread are scaled independently by the selected Range, including the Cubic range.

Ring Mod

Added a Spread parameter that offsets carrier frequency between stereo channels.
At 200%, the left channel runs at half the Frequency value and the right channel runs at double the value. At 50%, the scaling is reversed.
Spread provides useful presets such as -5 c and +20 c. Other values can be entered in cents and are automatically converted to percentages.

Mid-Side

Replaced a single parameter with two independent controls for mid and side signals, making it easier to adjust stereo width without affecting the centre.
Both controls support values up to 200%.

Other Changes

Noise Gate: Improved the DSP for smoother gating.
Parameters with semitone units now use st instead of s to avoid confusion with seconds.
Factory Patches: Added a “Feedback Delay” subpatch that makes it easy to create an audio feedback loop with a delay.
Stack has moved from Collection 4 to the free Collection 0, making it available to all users. Like Group, Stack is a fundamental building block for building patches, offering parallel processing alongside Group’s serial processing.
Mod Steps: The module has graduated from Mela Lab and can now be found under the Modulator category.
MIDI Echo: The module has graduated from Mela Lab and can now be found under the MIDI Processor category.
