Midiflow Limiter (Audiobus) 1.0.6

This MIDI effect application designed for Audiobus 3 serves as a sophisticated filter and remapper for note velocities. It enables users to selectively filter out notes that fall outside a specified loudness range or to remap these velocities to alternative values, creating a nuanced control over sound dynamics. Users can also deploy multiple instances of this effect to develop velocity layers, thereby triggering distinct sounds based on the velocity of incoming notes.

• Specify a customizable velocity range for filtering notes.
• Utilize a curve to effectively remap velocities.
• Remap velocities to a fixed value for uniformity.
• Employ multiple instances of this effect within Audiobus for enhanced versatility.

NOTE: This application necessitates Audiobus 3. It must be inserted into one or more MIDI effect ports to influence the data traversing the respective pipelines.

FILTER NOTES BY VELOCITY
The range selector located at the top allows users to define the velocity thresholds for the notes that they wish to filter. Any notes possessing velocities that fall outside this defined range will be excluded. A real-time display of incoming note velocities facilitates effortless adjustments of the filter range according to keyboard input or sequencer output.

CREATE VELOCITY LAYERS
Midiflow Limiter can be added multiple times within an Audiobus configuration, particularly useful for those utilizing external keyboards. By establishing two routes with the keyboard as the source and connecting them to two separate synths, users can apply different velocity ranges via Midiflow Limiter in each route. Consequently, only notes within the predetermined velocity ranges will trigger their corresponding sounds.

REMAP NOTE VELOCITIES WITH A CURVE
The remaining note velocities, unfiltered from prior settings, can be remapped using a velocity curve. The horizontal axis represents all potential incoming velocity values, while the curve illustrates the function employed to alter these velocities. Users can manipulate four handles to modify the shape of the curve.

The applications of velocity remapping are diverse; for instance, shaping a piano sound to exhibit greater strength by employing a specific curve will elicit louder notes earlier based on the force applied to keys. Conversely, a curve with an opposite bowing effect may render sounds softer. Other configurations can be used to expand or compress the range of velocities effectively.

REMAP NOTE VELOCITIES TO A FIXED VALUE
For those looking to simplify their sound by eliminating velocity variability, it is possible to remap note velocities to a single fixed value, visualized as a horizontal line on the curve.
