Midiflow Limiter (Audiobus) vs JAX Unisonic (Audio Unit) Usage & Stats

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.

JAX Unisonic (Audio Unit)

JAX Unisonic is a special Audio Unit, able to produce up to 8 additional voices from any audio input (also polyphonic audio) by multiplying and shifting it in pitch and other parameters. Audio Units require a host application for operation. The concept of JAX Unisonic is loosely derived from ‘Unison’ which was adopted from the ancient analog synthesizer world, where manufacturers and sound designers intended to fatten the sound by multiplying and stacking available voices together. Also digital synthesizers did adopt this technique to fatten sound sources. Due to the instability of analog oscillators and components and some wilful detuning, an interesting sonic effect is achieved, giving the produced tones significantly more presence and life. Unison voices are still excessively used in modern music styles today. (In classical music compositions ‘unisono’ basically means a performance, where multiple instruments or voices play the same parts in an ensemble fashion.) Technical Now JAX Unisonic can simulate this sonic effect with any audio source by incorporating a bank of independent time domain pitch shifters, that are optimized to detune and spread artificially multiplied voices in panorama. It can be understood as a kind of super chorus generator or an ensemble like effect with variable, realtime controlled intensity and pitch relation. But it is clearly something more. With JAX Unisonic you can create up to 8 additional voices, that will be passed thru a chain of pitching and positioning, creating massively fattened sounds with any kind of voice input. Additionally you may transpose each voice individually per semitone to max. +/- 1 octave, something that cannot be achieved with usual choruses, unison or ensemble effects and moves the results slightly in the direction of the category “harmonizer” effects. Although the harmonic results can be programmed (automated) freely and are not auto generated in any way, as on some available other harmonizers. The used pitch shifters in our JAX Unisonic are NOT based on the phase vocoder paradigm (FFT) and do not introduce the static latencies, which are unavoidable by the latter. A time domain pitch shifter in contradiction, uses very small delay buffers, where the latency is dynamically adjusted (dependent on the used pitch shifting amount) and much smaller and nearly latency-free. Such pitch shifters are better situated for live usage therefore. Although, such pitch shifters sound slightly more raw and tend to produce disharmonic overtones with more extreme values. Usage JAX Unisonic may be used as a massive unison effect generator or more decently for creating various, more subtile effects for improving sonic qualities of parts in a composition. For instance controlled voice detuning, manual pitch correction, doubling of vocals or solo instruments or just to give some boring voices more interest and static sound some special movement. It is even usable with drums, adding subtile or even massive new frequency components.
