HOW TO USE

Interface

Details of each Stage Gate Mode
	OFF: gate-low
	Single Gate: The first clock pulse of the stage drives the gate high, and the remaining clock pulses of the stage drive it low.
	Multiple Gate: The gate goes high with every clock pulse in the stage.
	Multiple Gate / 2: The gate goes high every four clock pulses on the stage.
	Multiple Gate / 3: The gate goes high every four clock pulses on the stage.
	Multiple Gate / 4: The gate goes high every four clock pulses on the stage.
	Probability / Programmable Gate: This mode offers two options: a probability mode where the gate randomly goes high or low with each clock pulse on the stage, and a mode where you can program the gate pattern in the Setting Menu.
	Long: The gate will rise along the entire length of the stage.

Play Mode Details
	forward: Advance the sequence forward in ascending order. After playing the final stage set in Stage-Control, the sequence is reset.
	Ping-Pong: Plays forward, then plays the final stage, and then plays in reverse, starting from the first stage.
	Random: Plays stages randomly within the range of stages set in Stages Control. In A/B Serial Split mode, sequence A or B is randomly selected and played forward. In Split Parallel mode, a stage from sequence A is randomly selected, and sequence B is played forward.
	Fixed Length: Plays a predetermined number of clock pulses and continues playing forward until it restarts from the first stage. The sequence length of the clock pulses is determined by a value that is a multiple of 4 in Stage Control.

FIXED LENGTH TIP: Setting the STAGES knob to '4' will cause the sequencer to play a 16-clock pulse sequence until it resets. The sequence length is not affected by the overall value of Stage Counts. This mode is suitable for locking the sequence into a drum machine and creating sequences like repeating grooves.

Split Mode Details
	No Split: Always play in normal operation.
	Serial Split Mode: Sequence A is played X times, followed by sequence B Y times.
	Parallel Split Mode: Plays sequences A and B simultaneously. Sequence A's CV and GATE are output from CH1 and MIDI NOTE OUT, while Sequence B's CV and GATE are output from CH2.
	Activate the Split Point setting and repeat the count in both AB sequences. Move the green LED cursor with the two blue buttons to determine the split point (sequence B start point) and set with the red button. The two blue buttons move the green LED cursor to define the repeat count for sequence A, and the red button sets it. Similarly, the two blue buttons move the green LED cursor to define the repeat count for sequence B, and the red button sets it.

Voltage Mode GLIDE PROG

● GLIDE PROG allows you to set glide on/off for each stage. When the sequencer is stopped, you can set the stored CV values ​​for channel 2's CV and MIDI note velocity.

To set the glide per stage, the two blue buttons move the flashing green LED to select a stage, and the red button toggles glide on/off.Stages with glide on will have a green LED.

When the sequencer is stopped , you can use the Gate Time knob to adjust the Stored CV value of the stage, indicated by the blinking green LED. This Stored CV value is used for the velocity of the MIDI note output. If you are not in AB Paralleled Split mode, the Stored CV value is output from the CV OUT on channel 2.

Settings Menu

Press and hold the red button for about 1 second to access the Settings Menu.

LEVEL 1 Top menu

The first level of the Settings Menu is indicated by a green on/off LED and a red cursor LED.

Use the two blue buttons to move the red cursor and select any item, then use the red button to toggle the item on/off or enter its submenu, if available.

Within the Settings Menu, you can exit the current level by pressing the gray button .

1. Scale Quantise Sub Menu: See next submenu.
2. Programmable Gate Pattern Sub Menu: See next submenu.
3. Long Gate Slur ON/OFF: When set to ON, gates are not cleared at the end of Long Gate mode, allowing gates to be created that lead to subsequent stages.
   TIP: You can create TB-303 style slides by setting the stage glide ON after a longgate containing a slur.
4. A+B CV offset ON/OFF: When set to ON, adds the CV of sequence B to the CV of channel 1 to create a root note offset or key change. * Root note offset for MIDI note input is disabled.
   TIP:You can create a pattern that loops in sequence A and change the key of sequence A with a slower pattern in sequence B.
5. Clock Multiply ON/OFF: When set to ON, the sequencer's clock (both internal and external) is doubled, allowing 8 minute notes with an 16 minute note clock.This is suitable for synchronizing with equipment that employs 2PPQ, such as the Korg Volca and Teenage Pocket Operator.
6. MIDI Input / Reset Input Toggle: The MIDI input jack can be switched with MIDI IN[OFF] or RESET IN[OFF].If using the reset input, set the MIDI TRS switch on the back of the module to the 'B' position.
7. Sequence B Gate -> Reset ON/OFF: When set to ON, it allows the reset of sequence A to be triggered from the high gate of sequence B.
8. Pre/Post Scale Root Note Offset: Root note, A and B CVs, and MIDI IN offsets can be applied before [OFF] or after [ON] scale quantization.

LEVEL 2 submenu

The second level of submenus is indicated by a red on/off LED and a green cursor LED. Here too, you can exit the submenu and return to the top menu using the gray button .

   Also, by operating the Gate Time knob, you can adjust the root note of the scale in chromatic scale from C to B. 
2. Programmable Gate Pattern Sub Menu: GATE MODE'??????'Set a custom gate pattern for the mode.
   Aboutblue buttonMove the green cursor LED to any position with ,Red buttonPress to toggle each position on/off.

Sequencer Utility Mode

Several utility modes can be accessed by pressing and holding specific buttons while the module is powered on. 

MIDI TO CV MODE

In this mode, the M185 can be used as a MIDI to CV converter .

As the module powers up, press and hold PREV [blue left button] until the LED stops moving.

Connect a MIDI source, such as a keyboard, to the MIDI IN jack using the included MIDI/TRS cable.
Input MIDI notes are converted to CV and Gate and output on channel 1, velocity or modulation CV output on channel 2.
MODE switchcan be used to select the behavior of the CH2 CV output from the following options:

• →: CV2 outputs the velocity of MIDI notes. 
• ↔︎: CV2 outputs pitch bend wheel data.
• ? : CV2 outputs modulation wheel data.

Stages knobto select the MIDI channel.

UTILITY MENU

When the module powers up, until the LED stops movinggray buttonpress and hold .
This menu is indicated by a green on/off LED and a red cursor LED.

Use the two blue buttons to move the red cursor LED to select any item, and use the red button to toggle the item on/off or enter its submenu if available.

1. Master / Slave select (not available in DIY version)
By connecting two M2s, you can create sequences of up to 185 stages.
Use a 3x2 ribbon cable to connect the SLAVE sockets on the back of both modules.
Be careful not to accidentally connect to the expander socket.The module may fail.

Red buttonto switch MASTER MODE on/off,gray buttonPress to start the sequencer.
If successful, you will see a red LED animation across the two modules.
If you have problems, restart the module.

2. MIDI CH & Clock Subdiv Sub Menu
Sets the MIDI channel for MIDI note input and output.Also sets the subdivision of the MIDI clock and the internal clock.

clock subdivision
Use the two blue buttons to select any stage to define the amount of subdivision with the red LED cursor.Each stage represents a multiple of 2 and is indicated by a lit red LED.
TIP: Stage1=Subdivision of 6, Stage4=Subdivision of 24

MIDI channel
Select MIDI input and output channels with the Gate Time knob (green LED).

FIRMWARE UPDATE MODE

Press and hold the red button when powering on the device . The two LEDs on the left side of the sequencer will indicate that it is in firmware update mode.

Firmware updates are performed by transferring a MIDI sysex file via MIDI input.
