SETTING OCTAVE

In octave setting mode, adjust the higher and lower octaves of the range.

  • Press OCT to enter octave adjustment mode. The OCT button indicator flashes and the display shows the current octave value.
  • Press ▲ or ▼ to adjust the octave value, the screen will display the upper and lower octaves value.
  • The octave adjustment mode is automatically exited when no operation is performed for an extended period of time, and the octave adjustment mode can be exited by pressing OCT again.

SETTING TEMPO

There are two ways to adjust the Tempo value.

  • The first way is Tap Tempo. You can change the Tempo by pressing the TEMPO TAP button 2 to 4 times in a row.
  • If you need to adjust the Tempo value precisely, please refer to the second way below.
  • Press the TEMPO TAP button once to enter tempo adjustment mode, the TEMPO TAP button indicator flashes and the display shows the currently set speed.
  • Press ▲ or ▼ to adjust the Tempo value, which ranges from 40 BPM to 240 BPM.
    If you press and hold ▲ or ▼, the Tempo value will change rapidly in succession.

KEYBOARD MODE

  • In the keyboard mode (default mode), you can directly press the keys on the keyboard to play.
  • Follow the steps below can set equipment parameters.
Accent
  • Press the ACCENT button, the ACCENT button indicator turns on to indicate the accent (bass) effect is triggered.
  • To adjust the accent volume via the ACCENT knob on the panel, press the button on the keyboard, and an accent effect should be heard.
  • Press ACCENT again to turn off the accent function.
Hold
  • Press the HOLD button, the HOLD button indicator turns on to activate the hold function. If released the button now, MIDI and sound will remain output.

CREATING A PATTERN

  1. Activate the record function
    • Short press REC/EDIT once, the REC/EDIT button indicator will turn on which indicate the record function is active while the step LED 1 will flash. (The current being step LED will keep blink during the record function).
  2. Initialize the current pattern
    • Press and hold the CLEAR/REST about 2 seconds to initialize the current pattern. (This operation will not change the stored pattern)
  3. Enter a note to step 1

MIDI DEVICE CONNECTIONS

B1 supports the universal MIDI standard protocol, which allows you to control external MIDI devices with the B1 and to control the B1 with external MIDI devices.
MIDI DEVICE CONNECTIONS

  1. B1 connected to the computer via USB
    • B1 supports the standard USB MIDI protocol and you can connect the USB port of the B1 to the USB port of your computer with a USB cable.
    • You will see the B1 in the list of MIDI devices on your computer when connected, without the need of installing any drivers.
  2. Use external MIDI devices to control B1
    • If you want to control the B1 with an external MIDI keyboard, sequencer, or other MIDI devices, please use a MIDI cable to connect the MIDI OUT port of the external MIDI device to the MIDI IN port of B1.
  3. Use B1 to control external MIDI devices
    • If you want to use B1 keyboard, B1 sequencer or B1 arpeggiator to play sounds or control an external MIDI device, please use a MIDI cable to connect the MIDI IN port of the external MIDI device to the MIDI OUT port of B1.

You can set some MIDI-related parameters on the "APP" or the "Power on Commands", please refer to "APP" and " Power on Commands" sections for details.

MIDI CHANNEL

  • When exchanging data with an external MIDI device, you must ensure that the unit's MIDI channel setting is the same as the MIDI channel setting of the external MIDI device, so as to exchange data correctly.

"LOCAL" OPTION

  • The Echo Back setting of some external devices or computer DAW systems allows notes or other MIDI messages from the B1 to be quickly and easily transferred to other MIDI devices. However, when you play a note on the B1, the Echo back function of the external device may send the note message from the B1 back to the B1, which may cause the B1 to be triggered a second time. To avoid this problem, you can disconnect the LOCAL connection between the B1 and the external MIDI device via the "LOCAL" setting.
  • In addition, you can turn off the local connection with keyboard and local devices via the "LOCAL" setting, so that pressing a button on the local keyboard will only output MIDI messages, while no sound will be played locally. This allows you to use the B1 as a MIDI keyboard without affecting the B1 itself. All "LOCAL" settings can be changed on the APP, please refer to the "APP" section for details.

MIDI IN TRANSPOSE

  • The transpose setting allows you to transpose inputting note messages, and you can change this setting on the APP. For details, refer to the "APP" section.

ACCENT VELOCITY THRESHOLD

  • When the velocity of the inputting MIDI note message is greater than the value set, the accent effect is automatically turned on. This setting can be changed on the APP. Refer to the "APP" section for details.

MIDI SOFT THROUGH

  • The B1's MIDI soft through function can forward inputting MIDI messages to a designated port, and you can turn the relevant channel on or off on the APP.
  • The main options are as follows. (Please refer to the "APP" section for details.)
    1. DIN to DIN: Whether to forward received MIDI IN messages to MIDI OUT.
    2. DIN to USB: Whether to forward the received MIDI IN messages to USB.
    3. USB to DIN: Whether to forward received USB messages to MIDI OUT.

MIDI OUTPUT FORWARDING

  • The B1's keyboard, sequencer and arpeggiator all output MIDI messages by default, and you can decide whether to output MIDI messages to MIDI OUT and USB via the APP.
  • The main options are as follows. (Please refer to the "APP" section for details.)
    1. Keyboard: Local keyboard (note message) output settings.
    2. RT: Local synchronous clock message output setting.
    3. Sequencer: Sequencer (note message) output setting.
    4. Arpeggiator: Arpeggiator (note message) output settings.

SYNCHRONIZING THE SEQUENCER/ARPEGGIATOR

  • The Clock Source option on the APP allows you to set the B1 as the master (Internal) or the slave device (DIN/USB/TRG).

SYNC IN/OUT

SYNC IN:

  • Connect the SYNC IN connector of the B1 to the SYNC OUT connector of an external device with a Sync Cable so that the B1 can be synchronized with the pulse signal of the external device.
    CONNECTING THE SYNC IN CONNECTOR

SYNC OUT:

  • Connect the SYNC OUT connector of the B1 to the SYNC IN connector of the external device with a Sync Cable, so that the B1 can output pulses and control the external device.
    CONNECTING THE SYNC OUT CONNECTOR
  • Note that you also need to set the Clock Source of the slave device to TRG (or SYNC IN) and check whether the pulse type settings are match (1PPS/2PPQ/24PPQ/48PPQ, etc.) to ensure proper operation.

CLOCK SOURCE
To use SYNC IN, you need to set the Clock Source to TRG or AUTO on the APP or boot command so that the B1 can synchronize with external devices.

  • Note that SYNC OUT is on by default at all times, no additional setting is required.

SYNC POLARITY

  • To complete synchronization of the B1 with external devices, the polarity of SYNC IN/OUT may need to be set as appropriate. This setting can be changed on the APP.

SYNC IN

  • Rise - B1 will perform synchronization when the input pulse reaches the wave peak.
  • Fall - B1 will perform synchronization when the input pulse reaches the wave trough.

SYNC OUT

  • Rise -- B1 will output a pulse at the wave peak.
  • Fall -- B1 will output a pulse at the wave trough.

SYNC RATE

  • When in SYNC IN, this setting determines how much the sequencer or arpeggiator advances when the pulse signal is received.
  • When in SYNC OUT, this setting determines how much of the sequencer or arpeggiator is advanced before outputting the pulse signal. - This setting can be changed on the APP.

SYNC IN
1PPS – Play 1 step per pulse.
2PPQ - Play 1/4 note every 2 pulses (KORG mode).
24PPQ - Play 1/4 note every 24 pulses.
48PPQ - Play 1/4 note every 48 pulses.

SYNC OUT
1PPS – Output 1 pulse per step.
2PPQ - Output 2 pulses per 1/4 note (KORG mode).
24PPQ - Output 24 pulses per 1/4 note.
48PPQ - Output 48 pulses per 1/4 note.
