The Yamaha CP300 is a full-size digital stage piano with stereo speakers.
Introduced in 2006, the Yamaha CP300 offered similar specifications compared to the P250 it replaced. However, the primary sounds have been significantly improved,[1] including emulation of "half-pedaling" effects, as well as sympathetic string resonance. The addition of "C" in the name is an homage to the mid-1970s CP series of electric stage pianos.[2] The success of the CP300 restarted the CP brand with other successful products in the series like the CP1 in 2009,[3] Reface CP in 2015, and the CP88 in 2019.[4]
The CP300 was discontinued in 2022 alongside the CP1, CP4, and CP40.
The Yamaha CP300 has a 88-key "Graded Hammer" keyboard with action that Yamaha described in the manual of the instrument as "virtually indistinguishable from an actual acoustic piano".
A hammer action keyboard includes a mechanism that replicates that of an acoustic piano. This is achieved by the attachment of a physical lever system and hammers to add more resistance to the keys played. On top of this, the keys are individually weighted, with the lower keys heavier than the higher ones — that’s called graded weighting.[5]
The keyboard is velocity-sensitive, including release velocity. It doesn't support aftertouch.
The CP300 has onboard stereo speakers, a 1/4 inch jack headphone output, as well as a stereo pair of balanced XLR outputs for PA usage, and a stereo pair of unbalanced 1/4 inch jack outputs.
The instrument supports up to 4 assignable foot pedals, with their default functionality being sustain, sostenuto, soft, and expression, respectively.
The CP300 supports DIN MIDI input and output, as well as MIDI through a USB port. USB usage requires drivers as it's not an audio class-compliant device.
The instrument also allows for stereo audio input to be reproduced via its speakers.
The CP300 is powered by the SWP50 tone generator that supports Advanced Wave Memory (AWM) dynamic stereo samples with 128 notes of polyphony. For the main grand piano sound, Yamaha digitally sampled each key in stereo at three attack intensities to obtain the tonal quality and presence, as well as key-off sounds, and hammer and damper noises of an acoustic piano. On top of this, the tone generator emulates sympathetic string resonance through its "soundboard" global effect. For non-grand piano sounds, other global effects like amp simulation, rotary speaker simulation, phaser, delay, tremolo, or auto panning can be used.
The tone generator also supports chorus of a few types, a couple of reverbs with controllable depth, and a master equalizer.
The instrument contains 50 original sounds, 480 XG sounds, and 12 drum kits.
