The Akai LPK25 is a compact 25 key MIDI controller that can be used wirelessly via MIDI Bluetooth. This controller is perfect for on the go producing and can be very useful to have in times where you need to lay down that urgent idea that has popped into your head! This controller works well with both Mac and Windows (what I mainly use) and easily integrates with most DAWs. I primarily use the LPK25 with Ableton when I am out and about and need to get my ideas down quick and effortlessly. Very satisfied with my purchase and a controller I use often!
