Caramel is a stereo distortion, crusher and fattener effect designed for Audiobus and Inter-App Audio. Caramel is perfect for adding lo-fi grit and punch to drums, bass, synths, guitar and more.

In addition to Audiobus and Inter-App Audio, Caramel can process external hardware by connecting a professional USB audio interface such as the Apogee Jam or Apogee ONE, and many more compatible USB interfaces. You can also use the built in headset microphone. Guitarists can use our effects live by connecting the output of their audio interface to an amp.

Caramel supports Core MIDI via the Camera Connection kit, USB MIDI interfaces, Virtual MIDI and WiFi connections. The MIDI Learn function lets you easily assign your MIDI controller's knobs and sliders to control Caramel's effect parameters.

Caramel features two distinct modes:
Perform and Tweak.

● Perform mode is focused around four XY touch pads. Touch to control Crunch, Sizzle, Crush and Bite independently for left and right channels.

● Tweak mode features large expressive sliders and additional effect parameters, allowing you to fine tune your sound.

Finally...a much needed effect.

I've been waiting for a dedicated, inventive and easy to use distortion / crunch effect and Caramel does this well and more in an easy to use interface that needs little explanation. I already used it on a track and with minimal tweaking I was able to fatten the track and add some edge to give the track more presence and urgency. If you're a musician or sound designer, tools like Caramel are very important, and sometimes you just need something that works. I think Caramel is one of those apps.

Real Tasty

Everything tastes better with a little Caramel on it...even broccoli. ;-). Seriously, this is one of those "really worth it" apps. Add a dash of crunch or blow it to smithereens, it's all up to you. As for me..well I just designed a lead guitar patch using Modular that totally sizzles with a little Caramel and I'm going to get back to playing it. Why don't you buy yourself a copy and come join me. It's totally worth every penny and twice as much in Canada.

Crunch time with pleasure

This caramel is crunchy (as much as you want with easy to use controls). This app can help to create some crazy gnarly sounds -- especially good for percussion tracks.

As with all Holderness apps, this is priced low, is easy to use, and is very high quality.

Music made on iOS is better with this series of apps.
