## What is iLep?

iLEP (Live Electronic Patch) is the result of many years of collaboration between composers and software engineers with the aim of creating a live-electronic instrument that shows its strongest musical performance in conjunction with an acoustic musical instrument and is especially suitable for use in concerts.

The first version of LEP was developed in Max-MSP by Wolfgang Heiniger and Thomas Kessler and later further developed by Thomas Seelig. Thomas Seelig then redesigned the original version and ported it for the iOS operating system to make the app runable on the iPad and thus accessible to a wide range of applications. Oliver Greschke joined later to help complete the app.

FEATURES

- Modular effect app with various routing and modulation options
- 6 different effects: 2x ring modulator, 2x filter (low, high, band), 2x pitch shifter, 2 delay, degrade, reverb, which can be precisely controlled graphically and by direct parameter input
- 16*16 patch-possibilities to route audio through different effects, like in a modular system
- Possible sound sources: Microphone/line in, sampler and pitch tracker, various test signals (sine, noise, sample)
- Various effect parameters can be modulated to different degrees (min... max) by a modulation source (e.g. Midi Express pedal): Excellent for live applications!
- An additional effect parameter can be modulated by midi notes
- Save, import, export and edit your own cue effect configurations
- Different cues can be combined to a set
- Import and management of own samples and entire sample libraries assigned to a set

### 2/5 — A waste of money.

*2021-07-06, version 1.2.0*

Obtuse design (worse than it looked). Tedious to use. Sounds are unremarkable.

### 5/5 — Impressive!

*2020-05-17, version 1.1.5*

It helped to watch a few demo videos first, but after you get the way the grid works, this is an excellent and incredibly powerful effects instrument. 

Glad this is still being supported.
