High Quality Mechanism for the Serious Player

With a newly designed key mechanism -taken from Roland's 30 years of synthesizer development - players can control a wide dynamic range with incredible subtlety. The re-designed key assemblies have a rounded shape for better reaction to the player’s touch and more comfortable glissando, plus changes have already been made to reduce the low mechanical noise of the PC-50 and eliminate vertical shake on the key strokes. The newly developed pitch bend and modulation design offers you easier and more expressive control. All these features add up to a keyboard that even the most discerning player can appreciate.

Twelve Selectable Velocity Curve Combinations

Pick from 12 velocity curves to precisely match your playing style. As the PC-50 has 4 different velocity curves and 3 kinds of sensitivity (Light, Medium, and Heavy), the player can find the combination that perfectly suits them and can produce the precise MIDI performance and programming of a true professional. In addition a Fixed Velocity Mode is provided where the PC-50 always outputs a fixed velocity (from 1 to 127) providing practical input for drum and percussion programming in step recording.

Side Panel Connections for Streamlined Routing

The rear panel of the keyboard is clean of connections so that you can easily have a computer monitor or laptop behind the keyboard - in the ideal position - especially for educational users. All connections are located on the side - USB, MIDI OUT plus separate Hold and Expression pedal ports.

3 Digit 7-segment LED and Rotary Encoder

The MIDI control function on the PC-50 is via a rotary encoder. Both easier and faster control than using the notes for numerical values. With this knob you can set up MIDI channel, Program Change, Control Change and more and instantly see the values on the LED.

FPT Low-latency MIDI Transmission

The MIDI processing in the PC-50 is compatible with FPT (Fast Processing Technology of MIDI transmission). This technology doesn't depend on music application you are using. It realizes stable, high speed, low latency, and low jitter MIDI transmission.

Three ways of Power supply : USB/Battery/AC Adaptor

The PC-50 is compatible with USB-Bus power. No power supply is required when connecting via USB cable. The PC-50 can also be powered via batteries (AA type x 4) or by an AC adaptor when you are playing in a studio. 3 choices of power for any situation. Batteries and AC adaptor (Roland PSA type) are optional accessories.
