– PRIMARY KNOB FUNCTIONS –

BLEND – Controls the wet/dry balance of the effect outputs. Turning the BLEND

knob to its minimum counter-clockwise position will yield 100% dry signal with no

wet. Turning the BLEND knob to its maximum clockwise position will give 100% wet

signal with no dry. A mix of the wet and dry signals will occur when BLEND is set

anywhere between the extreme settings.

VOICE Type – Selects one out of the nine voice options. Turning the VOICE knob

will change the filter type affecting the wet signal. A corresponding LED in the LED

ladder will blink briefly when a new VOICE is selected, indicating the change. The

STM does not blend between the nine voices. The VOICE knob acts like a switch;

moving it within a single voice will not produce varying results. To reverse the

polarity of the voice type, see the SENSITIVITY knob.

ATTACK – Varies the rise time of the filter sweep. The rise time is the speed at

which the envelope generator travels from its rest position to its maximum position.

With the ATTACK knob set to its counter-clockwise position, the filters rise at the

fastest rate (8 mS); set to its clockwise position, the filters rise at the slowest rate

(1200 mS).

DECAY – Varies the fall time of the filter sweep. The fall time is the speed at which

the envelope generator travels from its maximum position to its rest position. The

filter sweep’s decay begins after the ATTACK time has finished. With the DECAY

knob set to its counter-clockwise position, the filters fall at the fastest rate (8 mS);

set to its clockwise position, the filters fall at the slowest rate (1300 mS).

SENSITIVITY

(w/ voice polarity)

– Controls the input volume at which the filters

will start moving, varying the STM’s responsiveness to the instrument’s dynamics.

The SENSITIVITY knob has a center detent which signifies the off position for no

envelope response (a good position for use with an expression pedal). Turning the

knob away from the center detent will make the STM more responsive to your

playing. For chords and hard plucking, set the knob near the center. For single notes

and softer strumming, set the knob far from the center.

The SENSITIVITY knob is split into two sections: In the positive (clockwise)

half of the knob, the voice filters will sweep in the forward direction (ex: OW->EE for

the OW-EE voice or from low to high frequency for the WAH and BB voices). In the

negative (counterclockwise) half of the knob, the voice filters will sweep in the

reverse direction (ex: EE->OW for the OW-EE voice or from high to low frequency

for the WAH and BB voices).

– PRIMARY SWITCH FUNCTIONS –

PRESETS Encoder – This white knob has three functions:

1. Turn this knob clockwise or counter-clockwise to scroll through the presets,

though it will not load the preset. To load the selected preset, press and

release the PRESET footswitch.*

2. Press and hold the PRESET knob for 3 seconds to save a preset.*

3. Press and release the PRESET knob (without holding it down) to toggle the

Auxiliary functions on and off (the leftmost orange LED will light when

auxiliary functions are on).**

*See the PRESETS section for more on Presets.

**See the AUXILIARY FUNCTIONS sections for more on the auxiliary sound processes:

fuzz and LFO modulation.

BYPASS Footswitch & LED – Pressing the BYPASS footswitch will toggle the STM

between Effect mode and buffered Bypass mode. The associated red LED, near the

BYPASS Footswitch, will light to indicate Effect mode. When this LED is off, the STM

is in Bypass mode.

PRESET Footswitch & LED – The PRESET footswitch serves two purposes:

1. Press and release the PRESET footswitch to load a selected preset. If a

preset is already loaded, the STM will increment to the next preset in the

LED ladder. The PRESET LED will light up solid, indicating a preset is

loaded. A member of the LED ladder will also illuminate, indicating which

preset is loaded.*

2. Press and hold the PRESET footswitch to enter auxiliary knob edit mode.

While holding the footswitch, turn the knobs to adjust the auxiliary knob

parameters.**

*See the PRESETS section for more on Presets.

**See the AUXILIARY FUNCTIONS sections for more on these secondary knob

parameters.
