Ribn is a unique MIDI controller that allows you to add organic repeating modulation to your synths and effects. Developed by Nebojsa Petrovic, this app is designed to record and loop your finger movement, and you can assign a unique MIDI channel and CC# to each ribbon. Ribn is compatible with MIDI CC messages and can control any MIDI hardware synths, effects, eurorack modulars, drum machines, and more.

With 8 MIDI CC ribbon pads, you can choose any number of ribbons between 1 and 8. Each ribbon can be named to help you identify what parameter it's controlling. You can also turn off looping on individual ribbons to turn them into regular sliders. Ribn comes with three sets of configurations using presets that you can switch between, and it works with external hardware as well as other iOS synths. Ribn is compatible with iPhone (including iPhone X) and iPad starting with iOS 10.
