Sonic Logic, Knob Lab 3 & Central

The MIDI control apps and the Mac bridge — connecting them to your DAW.

Sonic Logic is a modular MIDI controller for iPad. It allows you to create your own arrangements and control an external software, this software can be on your desktop computer, on your iOS or you can control an external hardware device using an iPad to MIDI cable.

Sonic Logic is our flagship professional MIDI controller with a built-in editor that allows you to create complex, custom control surfaces with multiple components (knobs, faders, XY pads, keys, buttons, and jog wheels).

Knob Lab 3 is a simpler, more focused app that specializes in knob controls. It's perfect for users who need quick, powerful control without the complexity of a full editor. It's also free to try with a single knob layout.

Sonic Logic (iPad only):

  • iOS 12.0 or later
  • Optimized for iPad Pro

Knob Lab 3:

  • iOS 15 or later

For Mac (Sonic Logic Central):

  • Requires macOS 12 Monterey or later

You can connect Sonic Logic in the following manners:

  1. USB Connection (Macs only) - Run "Sonic Logic Central" on your Mac, connect your iOS device to your Mac and run the Sonic Logic app.
  2. WIFI - Connect your iPad and computer to the same WIFI network. (Latency will depend on your WIFI latency so to get the best results try to create an ad-hoc network.
  3. Bluetooth - Connect your iPad and your Mac using the Sonic Logic Central app. Both the iPad and the Mac need Bluetooth 4.0.
  4. Virtual MIDI - Turn on Virtual MIDI in the settings menu and control other iOS apps on your iPad.
  5. Cable - Connect using an iPad to MIDI cable, you can also connect using the USB Camera Connection Kit, but make sure that you connect it to a USB to MIDI cable (USB to USB will not work).

Sonic Logic sends out standard MIDI out, this makes it compatible with any program that receives MIDI. You do not need to make any special configuration to connect Sonic Logic to a certain DAW.

You can use 3rd party utilities that conform to Apple's protocols, like rtpMIDI.

Try removing all devices from your Bluetooth settings by going to the bluetooth icon on the top right edge of your screen and shift+option clicking on it.

Select "Debug" and then "Remove all devices".

Not in the foreseeable future. We would very much like to make one, but there are currently no plans to.
