The K-25m keyboard is an expansion module compatible with all Roland Boutique series synthesizers and has 25 velocity-sensitive keys.
The TB-03 uses Roland’s advanced Analog Circuit Behavior to replicate the authentic sound and character of the original TB-303.

The CV/Gate output allows for connection and control of analogue gear and modular synths.
The K-25m Keyboard measures less than 12 inches wide and can address a range from -4 to +5 octaves when used with the relevant module. It incorporates an adjustable stand with 3 positions for optimized viewing and performance. The keyboard is compatible with all Roland Boutique series synthesizers.
