ANALOG CONTROLS

ACCENT The accent control adjusts the amount of affect the filter’s envelope will have on both the

filter’s cutoff frequency and the amplitude of the sound when notes are programmed with an accent

in the sequencer. When this control is turned clockwise, the filter’s cutoff frequency will sweep up

for the duration of the accent decay, and the overall amplitude for accented notes will increase

accordingly with the setting of this control and the accent decay time. When this control is turned

counter-clockwise, accented notes will play at normal volume, however the filter’s envelope decay

will still jump to the shortest possible decay time set by the accent decay control.

ACC DECAY The accent decay control sets the shortest possible time for the filter’s envelope.

When notes are programmed with an accent in the sequencer, the filter’s envelope will use this accent

decay time to sweep the filter’s cutoff frequency, as well as boost the amplitude of the overall sound.

When this control is turned clockwise, the filter sweep time becomes longer, and accented notes will

play at a louder amplitude for a longer period of time. When turned counter-clockwise, the filter

envelope will be capable of creating short tight blips, and you may hear little or no affect on the

amplitude of the sound.

Note:

We have increased the range of this control to provide shorter and longer accent decay times

than the TB303 was capable of. To recreate the original accent decay time of the TB303, set the

accent decay control to the approximate position shown in the picture above.

CV MOD This control-voltage modulation amount control is used to make the filter’s cutoff

frequency follow the pitch of notes programmed into the sequencer. When an external modulation

signal is inserted into the CV IN jack on the rear panel, this external signal can then modulate the

filter’s cutoff frequency instead of following the pitches programmed into the sequencer.

Turning this control clock-wise allows the internal pitches, or external modulation signal to have a

greater affect on the filter’s cutoff frequency. When this control is turned counter-clockwise the

internal or external control voltages will have little or no affect on the filter’s cutoff frequency.

VOLUME The volume control adjusts the amount of audio signal sent to both the MAIN

OUTPUT and PHONES OUTPUT.
