Despite its diminutive size, the PCR300 has 32 full size keys with initial and after touch and a total of 50 assignable controllers. It's USB powered with all the connections on the side, not the back, to save desktop space. A DJ style crossfader allows control of two parameters simultanously and 18 touch sensitive pads facilitate drum programming and sample triggering.
This is what Edirol say about the PCR300:

DETAILS
50 x Assignable Controllers
The new PCR Series offer all the controls of previous models, but with the addition of even more controls that allow players to maximize the playability and operability of their MIDI hardware and software.
Assignable Controls & 18 x Velocity Pads
The new PCR Series has all the existing controls of the previous range, but adds exciting new features, such as velocity pads, perfect for playing drums and triggering sampler phrases. These precision pads can operate as buttons or velocity pads, and the handy LED indicators identify which of the two modes is selected.
Unique Crossfader & Long-Throw Sliders
The new Crossfader allows control of two parameters at the same time, and can be used to control synthesizer filters, DJ gestures and more. The new longer-throw sliders can control eight track faders and one master fader, or function as organ drawbars.
High-Quality Keyboards with Aftertouch
The new ultra-sensitive keyboards provide a wider dynamic range under the player's fingertips, while new aftertouch sensors allow the keyboardist to play more expressively. Smooth key action, keys shaped for comfortable glissando playing, silent operation, and stable key mounting all contribute to the enhanced playability of these keyboards.
Intelligent 'Dynamic Mapping' and Editor Software
Dynamic Mapping allows the PCR to automatically assign its physical controls to the most important parameters (e.g. in the current window of the software being used). Fifteen user memory locations are provided for storing your favorite setups. When using software that's not compatible with Dynamic Mapping, you can manually configure the Control Map settings from the PCR itself or the included PCR Editor Software (Mac or Win).
Side Panel Connections for Streamlined Routing
The rear panel of the keyboard is free of connections so that you can easily have a computer display (e.g. LCD monitor), ASCII keyboard, mouse & mouse pad, or laptop computer behind the keyboard, in the ideal position for use. This is especially beneficial for educational users in classrooms where space is often restricted. All connections are located on the left side - USB, MIDI IN/OUT plus separate Hold and Expression pedal ports. The PCR keyboard works with USB bus power. AC adaptor not required. (The optional PSB series AC Adaptor is sold separately.) A MIDI Merge capability from the MIDI input to either the MIDI output (or to the computer via USB) is also provided, and is convenient for advanced MIDI systems.
