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.

• To learn how to create processors with features found in traditional dynamics tools, check the module help.

• 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 Computer is a Mela Lab module and part of Collection 4.

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.

• Gain is a Mela Lab module and part of Collection 4.

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.
