Midi Echo AU vs Visual Multi
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
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.
- 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

This is an AUv3 compatible visual effect plugin which is intended for use inside your favourite DAW such as Cubasis, Auria, Meteor, AUM etc. It will not function as a standalone app. Visual Compressor is a 4 band compressor/expander which has the ability to analyse audio in real time giving an accurate and reliable spectrum representation of your signal as well as visual feedback of compression or expansion levels. It's uses range from final mastering of songs to dynamic manipulation and EQing of drum tracks. What makes this different from a normal compressor is the ability to compress or expand frequency ranges rather than the whole mix, with up to 4 bands available. This allows you to say tighten up a wayward snare drum while adding that extra punch to the bass drum while leaving the rest of the track intact. Each of the 4 configurable frequency bands can be modified using drag and drop operations directly on the graph making it easy to understand and quick to configure. Turn on the labelling option for colour coded details. Each band can function as an EQ allowing raising and lowering the bands gain by +/-24dB. You can assign either a compressor or expander to each of the bands. The compressor allows you to compress excessively loud sounds that exceed a specified threshold. Each band has configurable attack, release and ratio settings. The expander can be used to expand sound exceeding the threshold while compressing anything below it. This makes it useful for adding dynamics or even for noise reduction of a specific band. Each band has mute and solo buttons so you can audition what is coming through a certain band, great for use during band frequency setup. There is also a bypass option which removes a band from use and reduces CPU load. You can load and save custom presets as well as copy and paste settngs between instances. This is great if you need to setup multiple instances with the same settings. One of the cool features is the ability to save up to 3 mixes and switch between them for comparision. These mixes are actually saved as part of custom presets and as the saved state in your DAW. This is the third of three products which will make up part of the 'visual' range of effects. Main Features: ○ 4 distinct frequency bands. ○ Assignable Compressor or Expander. ○ +/-24dB gain per band. ○ Assignable Q to control precise crossovers. ○ Spectrum Analyser with 'Pre' and 'Post' monitoring. ○ Vertical shift and scale options for the spectrum. ○ Mute and Solo buttons for each band. ○ Save & Compare up to 3 separate mixes. ○ Bypass option to remove a band and reduce CPU load. ○ Create and save custom presets. ○ Copy / Paste presets between instances. ○ Compressor / Limiter with Auto Makup Gain. ○ Twin VU meters with RMS/Peak display as well as peak and gate lights per band. ○ Brick wall limiter. ○ Quick Reset options for each section of the effect.
