Midiflow Limiter (Audiobus)
This MIDI effect app allows you to filter and remap note velocities for Audiobus 3. You can set specific velocity ranges to filter out notes or use a curve to remap them to different values, enabling the creation of velocity layers for dynamic sound triggering.
- Filter notes by velocity range
- Remap velocities with a curve
- Remap to a fixed velocity
- Create velocity layers
- Use multiple instances in Audiobus 3

This MIDI effect app for Audiobus 3 is a filter and remapper for note velocities. Filter out notes that are too loud or too quiet, or remap them to different values. Use multiple instances to create velocity layers, which trigger different sounds based on the notes' velocity. + Specify a velocity range to filter out notes + Use a curve to remap velocities + Remap to a fixed velocity + Use multiple instances of this effect in Audiobus NOTE: This app requires Audiobus 3. Insert it into one or more MIDI effect ports to affect the data going through the respective pipelines. FILTER NOTES BY VELOCITY The range selector at the top allows you to specify the velocity of notes that can pass. All notes with velocities outside of that range will be filtered out. You can see in real-time what note velocities are coming in, so adjusting the range according to notes you play on a keyboard or generate with a sequencer is very easy. CREATE VELOCITY LAYERS Midiflow Limiter can be added multiple times to an Audiobus configuration. If you are using an external keyboard, you can build velocity layers. Just create two routes in Audiobus with the keyboard as a source and two synths as destinations. Then add Midiflow Limiter as an effect in both routes. You can then apply different velocity ranges for both synths, and only notes with a matching velocity will trigger their sounds. REMAP NOTE VELOCITIES WITH A CURVE The velocities of notes that have not been filtered out in the previous step can be remapped with a so-called velocity curve. The horizontal axis represents all possible values for incoming velocities. The curve determines the remapping function used to modify the velocities. Use the four handles to adjust the curve. Velocity remapping has various applications. You can make a piano sound a lot "stronger" with a curve like above, as louder notes are triggered "earlier" in terms of force applied to the keys. A curve with the bow to the other side makes it "softer". Other curves can increase or reduce the range of velocities. REMAP NOTE VELOCITIES TO A FIXED VALUE If you want to get rid of the velocity information in the notes, you can remap them to one fixed value. This corresponds to a curve that looks like a horizontal line.
Mid
This app offers unique stereo transformations, allowing for smooth, continuous intervals between L/R and M/S representations. It enables new modulation possibilities and can be used as a width-preserving panner or to transform any stereo effect into an M/S one.
- Continuous mid-side interval
- Width-preserving panning
- Spatial modulation effect
- Transform stereo effects to M/S
- Lossless stereo field preservation
- Tempo sync capable LFO
- Paired mode for effect modulation

Ever wonder what lies between the L/R and M/S representations? Mid-Side Continuum extends the definition of mid-side encoding to create a smooth, continuous interval allowing in-between values and gradual changes. Channel mode switches can now be turned into faders, opening up new modulation possibilities as well. The algorithm used by the plugin is a true extension of the mid-side encoder/decoder concept and doesn't involve any cross-fading or other artificial constructs. The plugin can be used in two ways: • In standalone mode, as a width-preserving panning effect, or a special modulation effect for spatially balanced sounds • In paired mode, allowing other effects to operate anywhere between L/R and M/S modes, with modulation options available FEATURES: • Provides a new kind of spatial modulation effect for stereo signals • Can be used as a panner that doesn't squash wide components (existing ambience, reverb, stereo FX), strongly panning narrow parts at the same time • A great companion for delays or delay-based effects: explore adding space or change the panoramic character without re-configuring delay taps • Turn any stereo effect or effects chain into a M/S one (or any graduation on the L/R - M/S curve), by sandwiching them between a pair of Mid-Side Continuum instances • Unlike panning, stereo panning, or binaural panning, Mid-Side Continuum preserves the exact geometry of the stereo field by using a lossless transform • Higher rates of change can be used to create additional kinds of effects (chorus, warble/flutter), depending on the width characteristics of the original input • A tempo sync capable LFO is available to add automatic modulation; the LFO phase can be offset to allow precise timing control and alignment THE PANNER FOR REVERB-RICH SOUNDS: Panning high-ambience and reverb-rich sounds need no longer result in squashed stereo images. The exact, full width of the stereo field is preserved when using Mid-Side Continuum as a panning tool. Unlike binaural panning, the overall stereo frequency response is kept maximally flat, thanks to the used algorithm's audio engineering-focused feature set. In fact, Mid-Side Continuum's algorithm is a lossless, completely reversible one (based on True Pan's technology). WRAP ANY EFFECT TO CHANGE / MODULATE THEIR STEREO MODE: Two Mid-Side Continuum instances can be conveniently linked in a way that the second one cancels out the transformation, restoring the original sound. Once linked, the second plugin will automatically re-align if parameters are changed in the first one, without missing a single sample. Between these two points, any number of audio effects can be inserted, all of which will receive the transformed signal instead of the original L/R one. This setup can be used in multiple ways: either to just turn any stereo plugin into a M/S one, or to modulate the stereo field of the wet signals (while keeping the dry signal intact) without the need for setting up additional routing, thus keeping tracks neatly self-contained. VERSATILE EXTENSION TO DELAY-BASED EFFECTS: • Alter stereo delay patterns or turn a mono multi-tap delay into a stereo one on the fly • Instead of having to choose from the two, explore any setting between L/R and M/S delay modes to select the best-fitting stereo response • Remove excessive L/R slappiness without losing any stereo width by spatially equalizing the delay output, filling in directions not populated by L/R taps • Improve the clarity of the mid channel / mono mix when combining panned delays with shorter notes or more rhythmic passages • Lessen any "clockwork-like" quality of panned delays that may be experienced with some instruments or passages • Change or fine-tune delay patterns that emerge in the mono mix when using stereo delays PLEASE NOTE: • An Audio Unit v3 compatible host app is required to use this plugin
