Gain Computer

Gain Computer is a modulator module for creating custom dynamics processors.
Depending on its settings and placement in a preset, it can be used to build effects such as a feedback compressor, upward expander, look-ahead limiter, side-chain gate, or de-esser.
It computes gain reduction or expansion from the input audio signal, similar to the gain computer in traditional dynamics processors.
Instead of applying the gain change directly, it generates a modulation signal.
This signal can be used to modulate a Gain module or any other parameter to produce dynamic effects.
The Gain module pairs well with the Gain Computer module, but the modulator supports a wide range of other use cases.
The module includes all the standard dynamics processor controls.
Type Parameter: Selects between Compressor and Expander modes.
Downward Processor: When the Range parameter is set to a negative value, the modulation signal is in the range [-100 %, 0 %], ideal for downward processing.
Upward Processor: When the Range is positive, the signal is in the range [0 %, 100 %], ideal for upward processing.

Transfer Curve: Shows how parameters affect the transfer function. A horizontal pan gesture adjusts Threshold, a vertical gesture adjusts Ratio.
Oscilloscope: Displays the modulation signal in real time. A horizontal gesture adjusts Attack, a vertical gesture adjusts Release.

Gain Module

The Gain module applies gain to the audio signal.
While designed to pair with the Gain Computer module, it can also be used independently in many other ways.
It has three parameters: Down, Up, and Range.
Although Down and Up use percentage units, gain is applied in decibels.
For example, with Range set to 24 dB, Down at 50 % applies -12 dB gain, and Up at 25 % applies +6 dB.

Latency Support

Added the Ahead parameter to Audio In and MIDI In modules.
The Ahead parameter sets how far in advance Mela requests audio and MIDI events from the host.
This allows processing to begin before the events would normally occur.
For example, it can allow an envelope follower to detect transients before they are heard.
This feature is also referred to as plug-in latency.
Most iOS hosts do not yet support plug-in latency compensation and may ignore this setting.
The "Latency Test" factory preset can help users check DAW support and assist developers with testing and debugging their hosts.

User Interface

Modulator Oscilloscope: The view XY-pan gesture now controls one parameter at a time.
Compressor Graph: The view XY-pan gesture now controls one parameter at a time.
Stereo Pan: The Pan and Spread parameter positions were swapped for consistency with other modules. Typically, the parameter below the graph is controlled by a horizontal pan gesture, while the one above is controlled by a vertical gesture.
Mela Lab: Instead of displaying a flask icon in the bottom-right corner, Mela Lab modules now use the flask symbol for the module actions menu.
In/Out Modules: The Audio In, Audio Out, MIDI In and MIDI Out modules are now more compact.
Rectifier: Fixed an issue where the dials appeared visually disconnected from the graph.
Many internal changes to improve the UI engine.

Other Changes

Default Preset: Updated the default instrument preset to make it easier to add MIDI Processor modules.
Factory Presets: Added a new effect preset.
Factory Presets: Fixed an issue where the "Digitise Drums" preset would not load.
Preset Browser: Fixed an issue where selecting a preset in a group with many presets would cause the list to scroll up.
Crash: Fixed an app crash caused by receiving an unusually large MIDI packet.
