Nikolozi updates Mela to v6.5 for macOS and iOS

6th May 2025

Nikolozi has updated Mela, a modular AUv3 plug-in for iOS and macOS, to version 6.5.

Digital Delay Module

The module has been redesigned and now includes the Delay Path sublane.
Since the sublane provides full flexibility for processing the delayed signal, the built-in 1-pole low-pass and high-pass filters are no longer necessary and have been removed.
To keep levels under control, the module retains the built-in feedback hard clipper that limits the maximum level to +6dBFS.
However, modules like Clipper and Meter can be used to manage and monitor levels in the Delay Path sublane to avoid triggering the clipper.
Existing presets that use the Digital Delay module will automatically migrate, with their sublanes populated by Band Pass and Clipper modules replicating the original filter and clipper settings.
The inserted Clipper will have its Type set to Hard, and Peak to +6dB, while the Band Pass will use the 1-pole filter type. Feel free to adjust these settings or replace the modules as needed.

The new module processes the Audio signal using a pair of virtual analog low-pass and high-pass filters arranged in series.
It's ideal for creating audio effects with a feedback loop by inserting it into the feedback path.
It offers 1-pole and 2-pole filter modes.
Band Pass is added to Collection 3.

Added the Peak parameter, which sets the clipping level within a range of -18dB to +6dB.
The graph now displays how the positive half-cycle of a sinusoid with unity amplitude is transformed by the module based on the current parameters.
The negative half-cycle is transformed symmetrically.
Dragging the graph horizontally or vertically adjusts the Drive or Peak parameter correspondingly.
Double-tapping the graph resets the parameters to their default values.
The Peak Indicator flashes when the input signal exceeds the Peak parameter value.

The Phase Inverter module has been renamed Stereo Tool and now offers extended routing options.
The module now lets each left/right channel's output be set to match its input, swap to the other channel's input, be phase‑inverted, or muted.
The updated "Ping-Pong Delay" preset utilises this module.

Stack: The module has a new mode, Ring Mod. When enabled, Stack's output Audio signal, or the Audio components of the output Poly signal, is the product of the output Audio and/or the Audio components of the output Poly signals of the submodules.
Stack Module: Fixed the scrolling not working using touch (worked when using a trackpad or mouse).
Lanes: Similar to module menu actions, added the "Replace Lane" action below "Insert Lane".
Feedback Module: Changed Level parameter's range from [-100%, 100%] to [-200%, 200%].
Feedback Module: To keep feedback under control, the module now has a built-in hard clipper that limits the maximum output level to +6dBFS.
Effect Module: The module graduated from Mela Lab and can be found under the Signal Router category.
Layer Module: The module has been removed since creating the same signal routing is simpler with the Stack and Group modules.
Modules: Submodules now dim when one of their ancestors is turned off.
Added the new Black theme to complement the White one. It's based on Martin Breault's MelAUM theme.
Settings: The Getting Started link has been renamed to User Guide and now opens the guide in the browser.
Voice Alignment: Fixed an issue where MIDI-to-Poly instances sharing the same MIDI input would lose voice allocation synchronisation when one of the instances was unbypassed.
