Manufacturer's description

KHarper Duo. Is Euro model? But it’s also a standalone synthesiser you can use this for both. It comes with a special back plate and a USB cable that you can power it standalone and use it without any eurorack Case but you can also build it in your system of course so it’s your own choice this is the KHarper duo

kHarper  Electronic Harp with 4 strings

We built a physical version of the Karplus-Strong physical model for strings. There is a whole group of Karplus-Strong algos and we are using a bunch of them. We built 3*3 sound engines that are each producing four voices.

kHarper is easily epic and cinematic. Can do big bwaaps as well as slow and emotional chords. Unlike a banana.

4 strings
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.

kHarper has a very wide range of sounds. You can go from wild distorted guitars to meditative soothing plinkies. Just like any other stringed instrument there are 10.000 ways to play.

Being able to touch these Karplus-Strong models adds the natural chaos of a physical manifestation. Plucking amazing.

If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch at info@signalsounds.eu if you have questions.
