TonePort / POD Studio KB37: FAQ


Q: What is the KB37 used primarily for?

A: It is a 37-key USB MIDI keyboard/control surface and TonePort USB audio interface. The KB37 will be able to send and receive MIDI CC information and process audio input and output across the USB connection to the host computer.


Q: What are the knobs in the center top of the keyboard for?

A: They are 4 software-assignable MIDI Continuous Control parameter knobs with 4 soft-buttons and a dedicated set of MIDI transport controls. The KB37 can control assignable MIDI parameters in most software synthesizer/samplers on the market today, along with most digital audio recording application sequencer track transport controls.


Note: The KB37 does not have any of it's own onboard sounds. It is a MIDI controller that sends MIDI data to the computer and any installed MIDI software synthesizer/sound software.


Q: What are the Audio Specs for the TonePort I/O section?

A: Sample rate conversion at 16 and 24 bit at 44.1, 48 and 96 kHz. 2 XLR inputs with mic preamps and +48V phantom power. 2 Guitar/Bass Inputs – use the Pad input for guitars and basses with high level pickup outputs, or the normal input. Dual analog VU meters (software assignable to input, record send, and output levels).


Q: Can I use GearBox editing software with the KB37?

A: Yes, the KB37 is a GearBox software supported TonePort family device.

Control Garageband With KB37

  • In order to control the Transport functions in Garageband with the KB37 you will need to have version 2.0.1 of Garageband or later.

  • This software is from the company: murat n konar
  • Once GarageRemote is installed and set up, start GarageRemote's Listener off by default) so that it can relay MIDI notifications to GarageBand. GarageBand responds to MIDI CC 007 and 010 for current track volume and pan, and these parameters can be assigned to the existing GarageBand MIDI preset of the Line 6 Audio-MIDI Devices settings.
