I have written an update to this review that can be found here: Line 6 POD Studio KB37 USB Audio Interface Review Update It’s truly a fantastic device and you can’t go wrong owning one.

I honestly can’t recommend the Line 6 TonePort KB37 enough. It’s extremely easy to take with me when I’m travelling. I really like how light and compact the TonePort-KB37 is. It also interfaces perfectly with Propellerhead Reason 4.0 which of course funtions seamlessly with Sony Acid Pro 6 as a plugin. I don’t know how they pulled that off but it’s truly amazing. One thing that truly blows me away about the device is the ability to monitor your effect laden signal with zero latency. You truly get a ton of features for a device that is priced so low. Last but not least it has two assignable VU meters and selectable 16-bit or 24-bit recording at 44.1, 48 or 96kHz. It includes 30 stompbox and studio effects as well as six high-end studio microphone preamp models. The software that comes with the Line 6 TonePort KB37 includes 18 guitar and five bass amp/cab models. As I said before, Sony Acid Pro 6 loves this audio interface. This makes it easy for guitarists to to punch in and out with the footswitches while they play.

The keyboard section features 37 full-sized synth-action keys, pitch/mod wheels, assignable transport controls and expression pedal input. The KB37 also has dual footswitch jacks to control effect on/off, tone select, tap tempo, sustain, start/stop and punchin in for your music recording software. With that many inputs and outputs it’s your total audio interface solution when multi-tracking your projects on your computer. It also has an S/PDIF out, TRS line outputs, TRS monitor input and an independent headphone jack.

The KB37 provides MIDI keyboard control as well as 2 mic inputs with built in 48v phantom power, a guitar/bass input and stereo line inputs. Sony Acid works perfectly with the KB37. I use this controller with my laptop and Sony Acid Pro 6. One of the finest pieces of equipment I have ever owned is the Line 6 TonePort KB37 Audio Interface and MIDI Controller.This little device has the power to be your sole interface into your digital audio software workstation.
