The CASIO VA-10 is an electronic musical instrument designed for both beginners and those looking for a portable and versatile keyboard with vocal effects. It offers a wide range of sounds, rhythms, and digital effects, including a unique Pitch Sensor and Harmony Arranger.
Function Description:
The VA-10 serves as a compact electronic keyboard with 32 mini keys and 6-note polyphony (max), though some tones are limited to 3-note polyphony. It features a "Tone Bank" with 100 preset tones, including various instruments like piano, trumpet, violin, and sound effects such as emergency alarm and car horn, as well as percussion sounds like rock drum.
It includes 12 "Auto-Rhythms" with patterns ranging from ROCK to 16 BEAT and SAMBA, allowing users to adjust the tempo. A "FILL-IN" button can be used to insert fill-in patterns into the rhythm.
A key feature is the "Digital Effect Bank," which provides 60 different digital effects, including reverb, delay, pitch shifter, ensemble, chorus, flanger, tremolo, vibrato, panning, distortion, and vocoder. These effects can be applied to both the keyboard's built-in tones and sounds input through the included headset microphone. Users can adjust effect parameters using the "EFFECT CONTROL" button and dedicated pads, and store up to 10 custom effects in "Effect Memory" (User Bank).
The "Vocoder" effect allows users to use their voice as a keyboard tone, creating unique vocal synthesis. The "Pitch Sensor" is another innovative feature, enabling users to "play the keyboard" by humming into the microphone. The keyboard detects the pitch of the voice and plays the selected tone at that pitch.
The VA-10 also has "Real-Time Memory" for recording up to 1,300 notes played on the keyboard. This recorded melody can then be enhanced with the "Harmony Arranger," which automatically adds accompaniment chords from four available patterns. The "Melody Quantize" function helps correct recording errors, including Pitch Sensor distortion and off-beat notes.
For entertainment and learning, the device comes with six original built-in "Demo Tunes," each pre-programmed with its own tone, effect, and tempo settings.
