Midiflow Limiter (Audiobus) vs QuantiChord

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.

"QuantiChord" is a MIDI effect that generates chords from incoming notes and quantizes the results to a pre-defined scale. It can be used as a standalone application or as an AUv3 MIDI effect plug-in. The chord is generated by adding up to 8 transposed notes to the original note played. Once the chord is generated, it is quantized to limit it to the selected output scale. The application supports full internal and external MIDI connections for input and output. An internal sound bank is included. The AUv3 MIDI effect plug-in supports multiple instances. A compatible host is required to run the plug-in. The host must support the Audio Unit v3 (AUv3) MIDI effect format. Hosts supporting AUv3 MIDI effect on iOS: Logic Pro, Cubasis, Beatmaker, AUM, Audiobus, NanoStudio, Auria Pro, apeMatrix. Hosts supporting AUv3 MIDI effect on macOS: Logic Pro 10.7 or later.
