getting started

when starting larc, you’ll be looping a blank section of tape. larc-start.png

this is indicated by an L in the top left corner of your screen, and the absence of a waveform drawing. press key 3 to toggle recording/looping. the counter in the top right corner tracks the record head position.

at this point, your arc will be focused on amplitude. turn arc ring 2 and 3 to bring up the amplitude of your 2nd and 3rd play heads, revealing them on the screen.


hold key 1 and touch an arc ring to change the arc focus.

while amplitude, panning, and cutoff behave intuitively as knobs increasing or decreasing a value, speed is less intuitive. larc-speed.png larc-arc-speed.png

first, use ring 4 to set a pre-speed value. then, move a ring 1 - 3 to set the play head speed. moving a ring counter-clockwise will set the play head to reverse.

press key2 to toggle record head and loop settings.


to clear the buffer hold key 1 and press key 2
