R12 overview

Terms used in this manual

Multitrack recorder (MTR)

A recorder that can record and play multiple tracks is called a multitrack recorder (MTR). The R12 can simultaneously record up to 2 tracks and simultaneously play up to 8 tracks.

Project

The R12 manages recording and playback data for a single song in a unit called a project. The audio files assigned to tracks and settings, including for panning and faders, are saved in project files. Up to 1000 projects can be created on a single card.

Region

The data from a single recording is managed for each track in units called regions. Regions for audio recordings and rhythms are shown as waveforms while synthesizer regions are shown as performance data (MIDI notes). Moreover, WAV and MIDI files on microSD cards and USB flash drives can be added as regions.

Snapping

This function aligns regions to a grid when they are moved or edited. This enables editing to be conducted efficiently.

MIDI file

This type of file contains MIDI performance data. The R12 can load MIDI files and add them as synth regions.

Effect

A wide variety of effects can be applied to sounds, including distortion, chorus and reverb. By adjusting effect parameters, you can create your own original sounds.

Patch memory

Patch memories store the effects used, their on/off states and parameter settings, allowing easy recall. Effects are saved and recalled in units of patch memories. Up to 3 effects can be added to a patch memory, and up to 50 patch memories can be stored.

Using effects

The R12 has effects that are equivalent to those in ZOOM multi-effects processors. In addition to reverb, delay and other individual effects, patch memories that contain up to three effects can also be selected. By selecting effects and patch memories, a variety of effects can be applied to instruments, voices and other sound sources.

Using the free Guitar Lab effect management application on a computer (Mac/Windows), you can add effects that are distributed online as well as edit and back up patch memories, for example.

Effects can be used in the following two ways.

Send effect
The input or playback sounds from individual tracks are sent to this effect. The sound with the effect applied is output through the PHONES and OUTPUT jacks, so it can be checked through headphones or powered monitors. The amount the effect is applied can be adjusted by setting the level sent to the effect (send level).
Reverb, delay and other individual effects, as well as patch memories, can be selected. When a patch memory is selected, insert (input) effects cannot be used.
The send effect does not affect recording data, but it does affect mixdown data.
This effect can be applied to multiple tracks, allowing it to be used, for example, to add reverb to every track.
Insert (input) effect
This effect is applied directly to the track, so it does affect recording data.
This can be selected from the patch memories.
Use this to record a guitar with distortion, for example.
The insert (input) effect can only be used on one track.

NOTE

If a patch memory has been selected for the send effect, an insert (input) effect cannot be used.

Using send effects

The send levels for signals sent to the effect can be adjusted for all tracks. The higher the send level the greater the effect.

Tap “Send Effect” on a Track Settings Screen (→ Opening Track Settings Screens).

Troubleshooting

If you think the R12 is operating strangely, check the following items first.

Recording/playback trouble

There is no sound or output is very quiet

Check the connections to the monitoring system and its volume setting.
Confirm that the volume of the R12 is not too low. (→ Playing projects)

Sound from connected equipment or inputs cannot be heard or is very quiet

Check the input level settings. (→ Adjusting input levels)
If a CD player or other device is connected to an input jack, raise the output level of that device.
Operate knobs and faders to adjust the volume.
Check phantom power settings. (→ Enabling tracks for recording)

Recording is not possible

Check recording track settings. (→ Enabling tracks for recording)
Confirm that the microSD card has open space. (→ Checking microSD card information)
Confirm that a microSD card is loaded properly in the card slot.
If “SD card protected!” appears on the display, the microSD card write-protection is enabled. Slide the lock switch on the card to disable write-protection.

Recorded sound cannot be heard or is very quiet

Confirm that the volume levels of the tracks are not too low. (→ Playing projects)
Confirm that the tracks are not muted and that other tracks are not soloed. (→ Muting tracks, Listening to selected tracks only (soloing)）

Other trouble

Computer does not recognize it even though it is connected to a USB port

Confirm that the operating system is compatible. (→ Using as an audio interface, Using as a card reader)
Connection operations must be done on the R12 to allow the computer to recognize it. (→ Using as an audio interface, Using as a card reader)
