Warm Distortion is real time distortion audio effect. It is a non linear distortion that works great with guitars, drums and other instruments. It clears the “hiss” sounds just like real tube amplifier. All algorithms are unique, created and designed for nice distortion effect. The app works as an Audio Unit plugin and can also be used as stand alone real time effect via the device microphone or using iRig or similar device. Features: - Unique distortion algorithms with natural tube sound - Gain - Level - Smoothie (hiss clearing magic slider) - Reverb (master reverb) + Camera controlled artificial feedback in standalone mode and built in noise gate. Just move your hand over the front camera to create feedback If you play acoustic instrument you can use headphones without a mic and put the phone close to your instrument so the app will work as realtime effect.
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
