One Control Crocodile Tail Loop

Thank you for your purchase of the Crocodile Tail Loop by One Control. The Crocodile Tail Loop is the flagship switcher from One Control. Create up to 70 presets with the easy push button auto saving system. The OC10 has 7 programs per bank and you can choose up to 10 programs for each program. The OC10 also is equipped with MIDI and can send program changes or be used as a MIDI through to be used in combination with other MIDI devices. Link two OC10 together with a simple LAN cable to access multiple pedals off stage. The OC10 also has the amazing BJF buffer from One Control included and also can be bypassed by using the not buffered input. The OC10 can also be a simple switcher but accessing the direct mode. Perfect for band practices or experimenting with pedals before you've decided how to set your programs. The Crocodile Tail Loop truly is one of the most innovative pedal switchers on the market.

To get the full potential of the unit and to avoid misuse, please read this user guide carefully.

Signal Path

Guitar signal feeds into OC10 input (NBUF IN or BUF IN), enters series LOOP1~LOOP7 when MUTE switch is off, then outputs from OUT-1 and OUT-2. When TUNER switch is pushed, the signal outputs to TUNER jack. Be noted the BUF OUT jack doesn't output when the guitar plug into NBUF IN jack.

Recall Programs

Press preset switches to recall presets, the corresponding LED lights up when a preset is active. Recall / bypass operation will not change the MUTE status.

TUNER

Press TUNER/L10 switch the guitar signal to TUNER jack and mute the output (OUT-1 and OUT-2) at the same time. Press the switch again will switch back the guitar signal to loops. TUNER function works individually, recalling programs do not affect TUNER function.

Bank UP/DOWN

OC10 have 10 banks from 1 to 10 ("0"), each bank stores 7 programs. Press BANK UP or BANK DOWN switches to change the bank, the numerical bank display blinks when the bank is about to be changed. Press any PGM switch to recall new bank programs.

Programming the loops

Press the program buttons to turn on/off corresponding loops, the loop status LED will be on/off accordingly, the memory automatically stores the status of all loops.

Configurate MIDI

A program allows to enable/disable the MIDI functions. Press MIDI ON/OFF button to turn on/off the transmit (TX) and receive (RX) of MIDI. TX/RX LEDs show the on/off status. The TX/RX status is stored into a PGM automatically. When the TX is on, a PGM recall will transmit a “MIDI program change” command via MIDI OUT jack on MIDI channel 0. The program change number is from 0 to 69, the number of Bank 1/PGM 1 is 0, the number of BANK 10/PGM7 is 69. When the RX is on, a “MIDI program change” on MIDI channel 0, from an external MIDI device will recall the corresponding PGM of OC10. If program change number is 0, it recalls BANK 1/PGM1 on OC10.

PGM/DIRECT MODE

OC10 is able to work in DIRECT mode. Holding the TUNER/L10 switch for 3 seconds will turn on DIRECT mode, the numerical display shows "-". In DIRECT mode, each stomp switch (L1~L10) turns on/off the loop1 ~ loop10 separately. Holding the TUNER/L10 switch for 3 seconds will turn off DIRECT mode and back to PGM mode. Note: in DIRECT mode the MIDI and LINK function are not available.

LINK FUNCTION

OC10 allows to link to another OC10 and work together. There are 2 link modes: SYNC and DOWNLOAD mode. In SYNC mode, a PGM recall will cause the same PGM recall on another unit. For example, recall BANK 1/PGM7 on OC10 A, the BANK 1/PGM7 on OC10 B will be recalled simultaneously. If you press PGM7 of BANK 2 on OC10 B, the BANK 2/PGM7 on OC10 A will be recalled at the same time.

In DOWNLOAD mode, the MASTER OC10 downloads the data to the SLAVE OC10. The SLAVE OC10 duplicates the MASTER OC10.

Push the LINK CONFIG button to change the LINK mode. The mode is SYNC when M/S LED is off. The mode is DOWNLOAD MASTER when M/S LED is red. The mode is DOWNLOAD SLAVE when M/S LED is green. The blue LINK LED lights on when two OC10 are connected with LINK cable.

Note: The MIDI IN is not available when OC10 is set as DOWNLOAD SLAVE device.
