Fiddlicator 4+

I really loved the feel of my solid body electric violin with a BTS bridge transducer. However I soon realized that I was never going to get a rich violin tone without a sound box. I tried tons of stuff on and off for 25 years. Short delay, reverb, eq, tube pre amps, acoustic resonator effects...
I am using an Apogee Jam lightening port adapter. I started this app and chose a violin impulse file and as soon as I even tapped the end of my patch cable, I could hear the the violin body acoustics, like when you tap the body of an acoustic violin. It sounds amazing with just the convolution without even messing with the other features. AUE played nice with Garage Band. No updates for a while. I hope the dev is still maintaining this. Some Cello impulses would be great too.

Once you get the hang of it, this app provides great features like an impulse response convolution engine, parametric EQ, reverb, and delay. You can set each of the 6 presets with it’s own Impulse response, and settings for all the other parameters. The trick is to set things the way you want, and then long-hold on the preset name. You can then change the preset name and hit SAVE. If you don’t hit save, then all the settings will be lost when you close the app or go to another preset.
I use the app with an iRig HD and it works great using the amp output or headphone output for silent practice.
I bought the upgrade so I can use much longer impulse responses. With that, this app does a much better job than a Mooer Radar IR pedal that cost me much more money.

For years, I have only used Fiddlicator as a mere convolution engine and to give sawtooth waves a sort of "acoustic" character, despite being synthetic. Now that I own an electric violin - the first violin I've played in over 17 years - I can fully appreciate what Fiddlicator has to offer. It gives my e-violin the acoustic qualities of a traditional violin I need, without shelling out hundreds or thousands of dollars for the real deal.

If I could give this app more than five stars, my rating would literally be over 9,000. Fiddlicator is easily one of the best apps I've downloaded for not only my iPhone, but also my iPad.
