Main Features
Welcome to the Loop Station!
The RC-300 is a pedal-type recorder that lets you record audio phrases from your guitar or vocal etc., and play them back by operating the pedal.
You can create a wide variety of performances by layering sound while you record and carry out play back in real time.
• You can save a maximum of approximately 3 hours of stereo sound (*total for all phrase memory) and up to 99 phrase memories.
• Three-track recording allows a wide range of performance possibilities.
• You can input audio in stereo.
• In addition to guitar (INST) input, a MIC input and AUX IN jacks are also provided. You can connect a microphone and loop-record your voice, or
record sound from your digital audio player.
• You can easily connect the RC-300 to your computer using a single USB cable. Once connected, you gain a digital audio connection with your
computer and the ability to export/import loop phrases (WAV files) (p. 36).
• You can apply an effect that is synchronized with the tempo of tracks while you play it back. You can use the EXP (expression) pedal to control
effects (p. 28).
• Two RC-300 units can be synchronized after connecting them together using a MIDI cable (p. 39).
