Walrus Audio Canvas Rehearsal

The Walrus Audio Canvas Rehearsal is your all-in-one rehearsal tool. Designed for musicians who use effect pedals, you can listen to your instrument through headphones, play with tracks via Bluetooth or 1/8” auxiliary input, and practice with a built-in metronome. The Canvas Rehearsal is the perfect end-of-chain solution when your gig requires your practice to become perfection.

The Rehearsal is loaded with features to simplify practice with maximum results. The OLED display gives quick readouts of BPM (Beats Per Minute), Time Signature, Beat Division, and Accent Note. Simply rotate the Screen Control Encoder to fine-tune settings and press down to cycle to the next parameter.

The BPM can be set in three different ways:

• Use the Tap Tempo button on the face of the pedal to quickly tap in a tempo.
• Press and hold the Start/Stop switch to enter “Tap Mode” then tap in a tempo by pressing down on the switch.
• Dial in a precise tempo by using the Screen Control Encoder to any specific tempo from 40 to 250 BPM.

Meter, Tap Division, and accent beat can be further customized with your BPM as well.

Flexible volume controls allow for your perfect practice mix. Separately adjust and set the volume for your instrument, metronome, and auxiliary audio input then use the main headphone volume to adjust the overall output.

The Rehearsal can be controlled via standard MIDI messages. Simply connect your MIDI controller to the Rehearsal MIDI “IN”. Downstream MIDI devices can be connected to the MIDI “OUT” which serves as a MIDI pass-through.
