Independent shopping perspective
The Korena take
Canvas Rehearsal is a compact practice pedal combining headphone amplification, Bluetooth connectivity, auxiliary input, MIDI connections, and a built-in metronome. Its OLED screen shows BPM, time signature, beat division, and accent note, while tap tempo, a Start/Stop switch, and the Screen Control Encoder offer several ways to set tempo. Separate level controls for instrument, metronome, and auxiliary audio let you shape a rehearsal mix before setting the overall headphone volume. Two 1/4-inch inputs and outputs support instrument and external-audio routing.
Strong match
Who this is for
- Private practice sessions using headphones, metronome settings, and a separate auxiliary-audio level.
- MIDI pedalboard setups needing parameter control or MIDI output pass-through.
- Rehearsal routing that combines instrument input, auxiliary audio, and headphone monitoring.

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I control the metronome tempo without the encoder?
Yes. BPM can be set with tap tempo, the Start/Stop switch, or the Screen Control Encoder.
02Can I connect a MIDI controller?
Yes. MIDI IN can control parameters, and MIDI OUT can pass MIDI to downstream devices.
03Can I adjust backing audio separately from my instrument?
Yes. Instrument, metronome, and auxiliary-input volume controls are independent.
