About

Midi Echo AU

This app creates repeating MIDI note effects, similar to audio echoes but for digital music signals. It allows for independent control of note-on and note-off messages, offering extensive customization for musical expression.

Highlights
  • Selectable echo types (fixed, ping pong, taper)
  • Adjustable number of echoes (0-20)
  • MIDI velocity reduction for quieter echoes
  • Define pitch interval for successive echoes
  • Tempo sync or mSec delay time
  • Set MIDI channel for echoes
  • Disable individual echoes
  • MIDI thru control

AUv3 Midi Fx - Midi Echo online manual here: http:/amssoftware.org/manual/MidiEchoManual.pdf Note : AUv3 midi apps need a compatible host (AUM,Audiobus 3, Cubasis, BM3 etc). So what is a midi echo? It is similar to the audio echo effect where copies of the original audio are repeated at regular time intervals but with some form of change (e.g. quieter). But unlike audio, midi is digital in nature (low resolution 8 bit mostly) and focused around the midi note on & off message used to control synths etc. This app acts on midi note-on independently from the note-off but when the note – off appears it echoes the release of the note-on in the same way the note-on was echoed (pitch interval etc) even if the UI controls have changed. UI Controls exist to allow you to: * Select the type of echo (fixed, ping pong, taper) * Vary the number of echoes (from 0 to 20) * Make echoes quieter by reducing the midi velocity * Define the pitch interval (semitone) of all successive echoes * Select the delay time between echoes either tempo sync or in mSec * Define the delay type (fixed, tempo, random 50, random 20) * Set the midi channel of echoes (1-16) so that other synths can select the echo only * Disable individual echoes - to allow you to play chords with a small or 0 delay * Set Midi thru to keep/remove the original note messages * Panic button to quickly turn off all notes * Setup control automation as all controls are AU Parameters

• Enhances Mix Loudness and Adds Harmonic Warmth • Full-Band and Two-Band Clipper in a Single Plugin • Quick, lightweight, and designed for effortless flexibility! • Precise Visual Metering for Fast Peak Control • Knee Curve Adjustment, from Super Soft to Hard • Shape Control of the Harmonic Profile • Dry/Wet Mix for a Natural, Balanced Sound • Low Latency with Optional Oversampling • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro FAC Clipper is designed to enhance your mix's loudness and add signature harmonic warmth. While it is based on a similar DSP architecture to the Clip processor in FAC Punchlab, it takes a different approach to clipping control, featuring an advanced user interface with precise metering to track and manage the peaks of the audio signal. The plugin also includes both a full-band clipper that processes the entire spectrum and a multi-band clipper, allowing you to independently clip low, high, or both frequency bands. This provides the flexibility to maintain transparent processing or experiment with creative adjustments, depending on your needs. Built with simplicity and flexibility in mind, FAC Clipper is quick, lightweight, and highly intuitive. The clean, streamlined interface lets you focus on what matters most; controlling the peak levels to maximize loudness while preserving clarity and avoiding the pumping effects often associated with heavily limited signals. Thanks to its precise waveform and level meters, using FAC Clipper is a breeze. Simply add the plugin to your track and adjust the input gain until the waveform meter reaches 0 dB. This gives you a clear view of the signal's dynamic range, making it easier to identify peaks. Next, set the ceiling just below the peaks you wish to control. You can also adjust the Knee parameter for smoother clipping and fine-tune the saturation to achieve the perfect warmth and character. Use the Mix parameter to blend the clipped signal with the original audio, allowing you to control the amount of clipping applied. This helps preserve the natural character of the sound while enhancing loudness and harmonic warmth. This is an AUv3 Effect and requires a compatible host to work The documentation is available at fredantoncorvest.com/FAC_Clipper.html
