Now in black! MicroSequence b is functionally the same as the original silver MicroSequence.

Hands-On Sequencing
With a simple, performance focused interface, the feature set of the Lifeforms Micro Sequence module speaks for itself. Eight sliders with integrated channel mute. Eight quantized scales. Eight sequencer direction modes. Sequences up to 8 steps. Four external modulation functions. Integrated tap tempo clock. Eight step external clock divider. Run/Stop transport button. Sequence reset button. Dedicated analog CV output. And more....

  • Micro Sequence Functions and Controls
    One of the strengths of the Micro Sequence is direct access to all of the features. The simple interface lets the user combine functions quickly to create a complex musical tool.

    Channel Sliders
    The channel sliders control the output voltage of both the quantized pitch output and the analog CV output. Placing the slider in the down position enables the channel mute functionality for the quantized output. When a muted channel is active, the gate output does not trigger and the quantized pitch output does not change from the previous active channel. The output of the analog CV jack is not affected by the mute functionality and will output a voltage corresponding to the position of the slider.

    Direction Modes
    The direction button determines the direction mode of the sequencer. Press once to show the selected direction. Press again to cycle through direction options. After selecting a new direction mode, the change takes effect on step 1. The first step of the cycle.

    • Forward - The sequence steps between channels 1 to 8 in order. Channel 1 represents step 1.

    • Reverse - The sequence steps between channels 8 to 1 in reverse order. Channel 8 represents step 1.

    • Pendulum - The sequence steps between channels 1 to 8 then reverses direction. Channels 1 and 8 are triggered twice to create a 16 step sequence length. Channel 1 represents step 1.

    • Stagger - The sequence steps between channels 1 to 8 in order with a 25% chance that the sequence will stagger back 1 step or ahead 2 steps. This creates a sequence that staggers back and forth as it steps between channels. Channel 1 represents step 1. Step 1 may be staggered past on any given cycle.

    • Skip - The sequence steps between channels 1 to 8 in order, skipping a subsequent channel each cycle. This creates a complex sequence of 56 steps. The first time through channel 1 is skipped, the second time through channel 2 is skipped, and so on. Channel 2 represents step 1 because Channel 1 is skipped on the first sequence cycle.

    • Transpose - Transpose splits the sequencer into two sets (channels 1-4 and channels 5-8). The top sequence (channels 1-4) is transposed by the bottom sequence (channels 5-8) running at 1/4 the rate as the top sequence. Channel 1 and channel 5 active represents step 1.

    • Random 1 - The active channel is selected randomly. There is no step 1 tied to random. Program changes happen immediately.

    • Random 2 - The active channel is selected randomly with the chance of a rest. There is no step 1 tied to random. Program changes happen immediately.

    Sequence Length
    The length button assigns the number of steps in the sequence. Press once to show the number of steps. Press again to cycle through and assign the number of steps in the sequence. When Transpose Direction Mode is active, the length button sets the number of steps in the bottom transposing sequence.

    Scale Modes
    The scale button sets the quantized pitch output scale. Press once to show the current scale. Press again to cycle through scale options.

    • Micro - Fine grained access to 250 note intervals per octave.

    • Chromatic - 12 step scale with note intervals at 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11.

    • Major - 7 step scale with note intervals at 0, 2, 4, 5, 7, 9, 11.

    • Minor - 7 steps per octave scale with note intervals at 0, 2, 3, 5, 7, 8, 10.

    • Blues - 6 steps per octave scale with note intervals at 0, 3, 5, 6, 7, 10.

    • Phrygian - 7 steps per octave scale with note intervals at 0, 1, 3, 5, 7, 8, 10.

    • Lydian - 7 steps per octave scale with note intervals at 0, 2, 4, 6, 7, 9, 11.

    • Dorian - 7 steps per octave scale with note intervals at 0, 2, 3, 5, 7, 9, 10.

    Gate In Mode Button
    The gate in mode button assigns the external gate input jack to one of four modulation destinations.

    • Reset - The sequence resets to step 1 when the incoming gate signal goes high.

    • Hold - The sequence pauses on the active step while the incoming gate signal is high.

    • Reverse - The sequence direction reverses when the incoming gate signal goes high. The sequence returns to normal when the gate goes high a second time. If the direction mode is set to random 1 or random 2, reverse mode enables the sequence to play forward.

    • Ratchet - The sequence gate output triggers 4 times per clock cycle while the incoming gate signal is high.

    Clock Button
    The clock button serves 3 functions.

    • Internal Clock Mode - The clock button acts as a tap tempo input to control the rate of the sequencer. The output of the clock is sent to the clock input/output jack as a 40ms 5 volt trigger.

    • External Clock Mode - The clock button acts as a clock divider selecting the division of the incoming clock signal. Select between ÷1, ÷2, ÷3, ÷4, ÷5, ÷6, ÷7, ÷8.

    • Switching between Internal and External Clock Source - Press and hold the clock button. Tap the run button to switch between internal tap tempo and external clock source. Slider 1 lights up to indicate internal tap tempo and slider 2 lights up to indicate external clock source is selected.

    Run Button
    The run button is the main transport control for the sequencer. Press once to start the sequencer. Press again to stop. The run button is also used to switch between internal and external clock sources while holding down the clock button.

    Reset Button
    Pressing the reset button resets the sequence to step 1.
