Velocity Filter vs Transit
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Velocity Filter
This audio unit plugin enhances synthesizer patches by making them responsive to MIDI velocity. It can function as a MIDI-controlled filter or volume control, adding natural musicality to non-velocity-sensitive sounds without altering their core tone.
- MIDI velocity to volume/filter conversion
- MIDI-CC and aftertouch control
- High-shelf filter modulation
- Preserves original patch tone
- Batch application to patches

WHAT IS VELOCITY FILTER? Velocity Filter is the fastest way to make all your synthesizer patches respond to MIDI velocity in a natural and musical way. Just add it to your audio unit effects on the synth track and you are done! WHAT DOES IT DO? It converts non-velocity-sensitive synths sounds into velocity-sensitive ones. Velocity Filter can be configured as either a MIDI-controlled filter or a MIDI-operated volume control. In filter mode, it adds or removes high frequency energy according to the velocity of each MIDI note, so that lower velocity notes sound softer and have less high harmonic content. You can control the amount of boost or cut and the frequency range. In volume control mode, it adjusts the volume according to incoming MIDI velocity. WHAT ELSE DOES IT DO? In addition to MIDI velocity, you can also control the filter using MIDI-CC or aftertouch controls. So you can control it in a variety of ways. HOW IS THIS BETTER THAN EDITING MY SYNTH PATCHES TO MODULATE THE FILTER CUTOFF BY MIDI VELOCITY? Most synthesizers respond to velocity either by modulating the cutoff frequency of a lowpass filter or by modulating the gain. Doing velocity response that way distorts the tone of the patch in an un-musical way, especially if it uses a resonant lowpass filter. Instead of modulating the gain of a lowpass filter, Velocity Filter modulates the gain of a high-shelf filter. The sound is very different, and can be applied on top of the existing filters in the synth patch without destroying the tone of the patch. Also, if you are browsing through a collection of 1000 patches, it's much easier to apply this filter to the output than to modify each and every patch to modulate the filter cutoff with MIDI velocity. However, it's not necessarily "better"; it's just very different. Read the limitations section below for why it's not always better. WHAT LIMITATIONS DOES IT HAVE? All notes go through one filter, so if you play two notes at the same time, with different velocities, it will set the filter for the loudest of the two notes. Also, the filter takes about 1 millisecond to change from loud to soft, so if you quickly switch from loud to soft, you'll hear the filter clamping down AFTER the initial attack. This is problematic for synth patches that have near zero attack time. Velocity Filter does not support GarageBand because GarageBand does not support sending MIDI messages to audio effects. Velocity filter is an audio unit plugin ONLY. It runs inside of host apps such as AUM, Audiobus, Cubasis, Auria, and Beatmaker 3.

This plugin kills static mixes! We teamed up with Andrew Huang to create Transit: A multi-FX plugin that’ll give your mix transitions super powers. Use it for build-ups, drops, motion effects, risers and sweeps – and keep your listeners constantly engaged. An Easier Way To Create Better Transitions: Transit hosts 18 powerful effect-modules, freely loadable across 7 slots. All effect parameters can be linked to a global Macro Control, which you automate to create complex FX transitions with one knob movement. A Creative Playground: The 18 effect modules in Transit are purpose-designed for transition duties. You get classic modulation effects, distortion and degradation options, motion FX, reverb, delay, two filter types – and even a synth oscillator and noise generator for adding risers and sweeps to your transitions. The Motion Sequencer: Switch from Macro Mode to Sequencer Mode to program and trigger DAW-sync’ed transitions with the click of a button. Each transition will start exactly at the next bar. This is ideal for live use. Or for writing perfectly timed automations into your mix session without entering the automation lanes. What's new in the iOS version: * Play View: A view that lets you trigger and control transitions without the visual clutter. * Ability to zoom in on individual modules for increased precision. * Easy-export your desktop presets to iOS by hitting the "E" key in your desktop version (v1.2 or later) and following the instructions. TL;DR * The ultimate plugin for creating complex, hand-raising, and jaw-dropping FX transitions with one knob movement * Perfect for building excitement between song parts and adding little moments of ear candy to your productions * Can be controlled with a single Macro Knob or a Motion Sequencer that triggers DAW-sync’ed automations at the click of a button * Engage “Sequencer Loop” mode to use Transit as an LFO tool for constant FX movements across entire tracks * A creative playground, suitable for both studio and live use
