Ribn is a MIDI controller with 8 assignable ribbons. What makes Ribn unique is its ability to record and loop your finger movement. This allows you to add organic repeating modulation to your synths and effects, kind of like complex LFOs. You can assign a unique MIDI channel and CC# to each ribbon. As long as your gear responds to MIDI CC messages you will be able to control it with Ribn.

• 8 MIDI CC ribbon pads
• Add modulation to your MIDI hardware synths, effects, eurorack modulars, drum machines, etc.
• Configurable MIDI channel and CC# per ribbon
• You can name each ribbon to help you identify what parameter it's controlling
• Turn off looping on individual ribbons to turn them into regular sliders
• Choose any number of ribbons between 1 and 8
• Full screen mode (removes navigation bar to help you focus)
• Switch between 3 sets of configurations using presets
• MIDI sending works while the app is in the background
• iPad landscape mode
• Select multiple MIDI outputs
• Ribbons record and loop your finger movement
• Use a wired MIDI interface, Bluetooth or Wi-Fi
• All settings are saved automatically
• Works with external hardware as well as other iOS synths
• Works on iPhone (including iPhone X) and iPad starting with iOS 10

• Control hardware MIDI synths parameters like the filter cutoff frequency, resonance, oscillator octave, etc.
• Control any soft synth in Ableton Live (or your favorite DAW) by connecting your iOS device to your Mac via Wi-Fi and choosing "Session 1" as the MIDI output in Ribn.
• Control your Eurorack modules by running Ribn through a MIDI to CV converter.
• Control other iOS synths like the Moog Model 15 or Arturia iSEM.
• Control drum machines and effects. For example, try controlling the room size of a reverb effect unit with a looping ribbon or the snappiness of a snare drum on a drum machine. The possibilities are endless.
• Daisy chain your MIDI hardware using MIDI Thru ports and assign each ribbon to a different MIDI channel. This way you can control more than one piece of hardware at a time. For example, you can assign the first 4 ribbons to a synth and the last 4 to an effect unit.

• Connect your MIDI gear (like a synth) to your iOS device using a MIDI interface (wired or bluetooth)
• Launch Ribn and select your MIDI interface in the settings page.
• Find out which CC# and MIDI channel your gear responds to (usually at the end of the manual) and enter this information in RIbn's edit view.
• Slide your finger on a ribbon to send CC values and control the parameters on your MIDI gear.

• MIDI is just the way electronic musical instruments talk to each other.
• CC (Continuous Controller) is just a way to control various parameters using MIDI. For example, a synth's filter cutoff frequency can be controlled using a MIDI CC signal.

** NOTE **
• Ribn is a MIDI controller and doesn't produce any sounds. To use Ribn you must connect it to a device that responds to MIDI CC signals (check your gear's manual to be sure).
• Ribn doesn't send note data, it only sends CC signals (you can't play melodies with it, but you can control various parameters like synthesizer filters, or effects settings).
• To connect your iOS device to MIDI gear you will need to buy a MIDI interface. A MIDI interface typically connects to your iOS lightning port and provides standard MIDI DIN ports to connect to your hardware. There are also bluetooth MIDI interfaces that connect wirelessly. Alternatively, you can connect to your Mac over Wi-Fi and control software synths that way. This setup is a little more complex but totally doable (I've tested controlling Ableton Live plugins over Wi-Fi with Ribn and it worked perfectly).
• Audiobus and AUv3 are not supported at this time. However, you can still control other iOS synths by routing the internal MIDI ports and having Ribn run in the background.

Like having 8 hands to tweak knobs real time

Beautiful. So many possibilities :) I’ve been hoping for something like this where you can assign cc to a channel and quickly record and control - think of it as 8 looping custom envelopes or complex LFOs you can tweak and loop live.

Great easy interface. Would be good to have a PAUSE button added to the right of center to pause live without having to menu dive - and on opposite side from the undo/clear button so we don’t accidentally erase a set.

Also would be great to be able to save a set of control IDs. Whether that’s saved like a preset we can name to remind us which device the preset is for, or whether there are 8-16 snapshot buttons.

Next I would love to be have an advanced setting menu where we can assign custom LSB type controls. Or even better MIDI LEARN to auto assign a knob tweak to one of Ribn’s looping faders. That would be killer - and save looking thru manuals. I also use MidiToolbox app for that purpose to see what cc a knob sends out what manuals are not nearby.

This app rocks. Works incredibly well if you know your way around MIDI or even if (like me) you don’t. I hooked it up to my Eurorack system using a Squarp Hermod via iConnectMIDI and via USB (both worked) and was able to modulate stuff without issues. Having that tactile interface is wonderful. If it can interface with my Eurorack, I’m not worried about it working with any of my other usage scenarios. Next thing to test would be using iPad and iphone simultaneously in one rig!

Simple, elegant, and EXTREMELY useful!

I’ve only recently (re)discovered how far iOS has come in music making, and this is an essential tool! With the ease of assigning CC values to synth parameters in AUM, for example, Ribn gives me 8 modulators that I can set, or “draw” for looping variations, and easily change on-the-fly. It’s true that good things come in small packages because this simple little app does a wonderful job!!
