It features five stereo tracks with dedicated controls, allowing for simultaneous playback and independent management of each track. The unit supports extensive customisation through 99 phrase memories for storing loops and settings, and it includes a wide array of onboard effects for input and track processing. Connectivity options are robust, with XLR and 1/4-inch inputs, USB for audio/MIDI interfacing, and external control via footswitches or MIDI devices. The RC-505 also supports real-time sampling and time-stretching, ensuring high-quality loop manipulation. Its design emphasises hands-free control and efficient user interaction, making it a versatile tool for both novice and experienced musicians seeking a reliable looping solution.
Key Specifications and Technical Details
The Boss RC-505 is equipped with powerful technical specifications that support its looping capabilities. It features 32-bit/44.1 kHz AD/DA conversion, ensuring high-quality audio processing. The unit provides 48 V phantom power for condenser microphones, which should be turned off when connecting devices that do not require it to avoid damage. The maximum recording time is approximately 1.5 hours per track and about 13 hours total across all tracks. The RC-505 includes over 200 integrated rhythm patterns and 16 drum kits, which can be used to accompany loops. The device weighs 1.8 kg and has dimensions of 420 mm (W) x 234 mm (D) x 67 mm (H). It is powered via an enclosed mains adapter.
The unit's connectivity is comprehensive, featuring: - Two balanced microphone inputs (3-pin XLR) - Two stereo line inputs (6.3 mm jack) - Three stereo line outputs (6.3 mm jack) - One headphone output (6.3 mm jack) - Two CTL/EXP jacks (6.3 mm jack) for external control - One MIDI input/output (5-pin DIN) - One Type-B USB connector for audio/MIDI interfacing - One power supply connector
The RC-505 has been available since December 2021. It supports USB storage mode, allowing users to back up recorded tracks as WAV files to a computer or load WAV files from a computer to the RC-505. When connected via USB, the display shows "Idiling..." to indicate this mode is active. The AUX input jack, designed for connecting an audio player using a stereo mini-plug cable, requires users to adjust the volume of the connected device to manage its input level.
Loop Recording and Management
Recording loops on the RC-505 involves using the track-specific buttons for each of the five stereo tracks. Each track has independent record/overdub/play and stop buttons, along with dedicated volume faders for mixing levels on the fly. To record a loop, press the track's record button; to overdub, press the same button while the loop is playing. To stop a track, press the stop button for two seconds or longer. The loop indicator shows the track's status, loop position, and level.
The RC-505 allows for quantisation to keep loops in time. Users can access the "Play:Quantize" setting to enable this feature. For tracks where Loop Sync is set to "ON," timing is corrected based on the tempo and time signature of the rhythm. Quantisation options include various settings to align loops with the beat.
To save a recorded loop, it must be saved as a phrase memory. Users can press the WRITE button while the loop is playing or stopped. If they decide to cancel the save operation, they should press the EXIT button. The unit also supports creating and saving custom phrase memories, which function like patches. To create one, users typically enter the editing mode for a track, adjust settings, and then save them to a specific memory location. Recalling a phrase memory involves selecting the saved memory to load its settings.
Additionally, users can save frequently used settings as a "User Set" for quick recall. The RC-505 also allows for backing up all phrase memories to a computer via USB storage mode before performing operations like a factory reset, which erases all memories including demo data.
Effects and Customisation
The RC-505 offers extensive effects processing with separate Input FX and Track FX sections. Input FX apply to the incoming audio signals during recording, while Track FX process the sound of the recorded phrases during playback. There are 49 input FX types, 53 track FX types, and 2 master FX types available. The unit includes six dedicated on/off buttons—three for Input FX and three for Track FX—which can be loaded with favourite effects. Grab-and-go knobs allow real-time parameter adjustment, such as filter cutoff and effect depth. With the Version 2.0 update, assigned effects can be used simultaneously, and new effect types have been added.
Global compressor and reverb effects are also available for polishing the overall sound. To add and adjust reverb, users can access the effects settings and modify parameters accordingly. Effects can be assigned to individual tracks, and when a track FX button [A]-[C] is pressed, the [EDIT] button of the target track blinks to indicate which track is affected.
The Assign function enables users to specify controllers, such as FX knobs or external pedals, to adjust Input FX or Track FX parameters or to switch them on/off. This allows for hands-free control and real-time manipulation during performances.
External Control and Connectivity
For hands-free operation, the RC-505 supports external footswitches or expression pedals connected to the CTL/EXP jacks. Compatible devices include the FS-5U and FS-6 footswitches. The functions can be assigned independently for each phrase memory. By default, connecting an FS-6 to the CTL 1, 2/EXP jack allows the CTL1 PEDAL to control UNDO/REDO and the CTL2 PEDAL to switch the rhythm level. The Mark Back function provides flexibility for undo/redo operations.
MIDI control is also available via the 5-pin DIN input/output, allowing integration with other MIDI devices. The RC-505 supports phrase import/export and pattern import via USB, enabling users to transfer audio files and rhythm patterns between the unit and a computer. The USB audio/MIDI functionality allows the RC-505 to interface with DAW software for recording and production.
The unit's user interface includes an LED/LC display for visual feedback of operational status. Buttons for Rec/Play, Start/Stop, Undo/Redo, and Tap Tempo are provided for direct control. A level fader allows adjustment of the overall output volume.
Rhythms and Playback Modes
The RC-505 features over 200 integrated rhythm patterns and 16 drum kits, which can be used to provide a backing track for loops. Users can access and adjust the tempo of these rhythm patterns. Each of the five tracks can have its own playback mode, such as multi, single, one-shot, or reverse, providing a wide range of creative looping behaviours. Tempo sync settings ensure that loops stay in time with the rhythm. The unit's design allows for independent control over each track's playback mode and sync settings.
Factory Reset and Maintenance
To perform a factory reset on the RC-505, users must follow specific steps, which will erase all phrase memories, including demo data. This operation cannot be undone, so it is recommended to back up all phrase memories to a computer via USB storage mode before proceeding. The reset restores the unit to its original settings, which can be useful for troubleshooting or preparing the device for a new user.
Conclusion
The Boss RC-505 is a sophisticated desktop loop station that combines extensive looping capabilities with powerful effects processing and versatile connectivity. Its five stereo tracks, dedicated controls, and 99 phrase memories offer musicians the flexibility to create complex performances in both live and studio settings. The unit's support for external control via footswitches and MIDI, along with USB audio/MIDI interfacing, makes it a comprehensive tool for integration with other gear and software. With features like real-time sampling, time-stretching, and quantisation, the RC-505 ensures high-quality loop manipulation. Users should note the importance of backing up phrase memories before performing a factory reset and exercise care when using phantom power to avoid damage to incompatible devices. Overall, the RC-505 provides a robust and intuitive solution for loop artists seeking to enhance their creative workflow.
