## What is Fiddlicator2 Core?

The Fiddlicator2 Core is an AUv3 audio effect plug-in which can simulate various kinds of acoustic environment by the convolution of the input signal with a custom Impulse Response. It is based on the convolution engine from the original Fiddlicator app redesigned to an AUv3 plug-in and extended with stereo processing.
 
The Fiddlicator and Fiddlicator2 Core AUv3 plug-in was developed to simulate an acoustic body resonance for electric musical instruments (mainly the electric violin), but it can also be used for a CAB simulation with proper impulse response files (not included).

The Impulse Response files can be imported directly from the iOS Files or via iOS Share.

If you are not sure the Fiddlicator2 Core is right for you please try the original Fiddlicator App which is available for FREE.

### 1/5 — Works beautifully in Loopy Pro

*2024-05-06*

This app works beautifully in Loopy Pro and does exactly what it is supposed to clearly and efficiently.  I gave it a five star rating because of that.

Unfortunately, it does not work yet in Luma Fusion (which would be really handy).  It just immediately locks up.

Fix that and you’ll still get the same five star review… but I would be even happier!  :-)
