ErrorInstruments Kharper EuroRack Electronic Harp

Two weeks ago, Paul Tas from ErrorInstruments released the Kharper Eurorack Module, built in collaboration with This Is Not Rocket Science (TiNRS)

The "Kharper -emuharphonica- Eurorack" is a kind of electronic harp, with 4 touch - and position- sensitive 'strings' on the frontplate of the module.

Every string is a voice. The strings are built out of two touch strips with an LED bar in the middle, showing you what kHarper is doing. 

Each string has a knob on top to set the tone and a CV -in below. You can also patch in a gate to pluck the string

Inside is a microprocessor that uses Virtual Modelling models to recreate different versions of the Karplus-Strong algorithm.

The Karplus-Strong algorithm, also called Karplus-Strong string synthesis, is a way to make sounds that are like plucked or hit strings, and even drum sounds too. It was created in 1983 by Kevin Karplus and Alex Strong. The method uses a short sound loop with a filter to repeat a small sound wave, which helps create a string sound that feels real.

I was already intrigued by the first demo's I saw earlier this year, and so far I love the sounds that i've heard of it from several sources that were lucky to get one from the first batch...

A wide range of sounds and soundscapes can be created, from spacey piano-like and harpy sounds.

It can also make percussive African drum-like sounds and even much more extremer noises...  ultimately you can push this module even leading to clipping, with cut-offs and distorted noises that even don't seem to belong there... the interesting area where even the calculations become unpredictable... lol

The Kharper is a 18HP wide skiff-friendly Eurorack module, but it can work as a stand-alone version too, powered by the USB connector on the back.

Via this connector you will also be able to download new sounds, algorithms, or even full alternative firmware. " In the future, there could be: • Traditional octave tracking • Different quantization schemes • Ambient or generative patches Or more experimental warm or noisy • New forms of sound design — all possible through open-source updates"

The Kharper comes with 9 (3x3), already impressive sounding models but in the future certainly different models will be downloadable.

INPUTS:

- MIDI in
- STRUM is a gate in that will strum all four strings
- Pond/River/Ocean - choice of sound engine
- Herring/Koikarp/Dolphin - choice of sound engine

The Tone and Decay of the selected sound engine can be tweaked with a knob or via CV.
All strings have a knob and CV in for tone and a trigger gate input to pluck the string see demo

OUTPUTS:  

- Control output Gate and CV

- Left/Right audio output

The first batch is already sold out
The kHarper will be available again in September.
