Samson’s Graphite M25 USB MIDI Controller gives you all the music production control you need for home studio and mobile applications. Packed into an ultra-portable design, the Graphite M25 features a 25-key velocity-sensitive mini keyboard, trigger pads with aftertouch, a full-featured control surface and additional programmable functions for advanced playability and customization. And with iPad/USB bus power and plug-and-play operation, the Graphite M25 makes it easy to express your most dynamic musical ideas, no matter where creativity strikes.
The knobs are quite ok but the materials used look really cheap and, at the top of that, key mechanism is linear like pressing a sustain pedal with your finger, not like any other keyboard... The drum pads are not sensitive so you have to hit them really hard... if you want to record from them, it will be really uncomfortable.
