Attenuate it! On the back of the BD101 you’ll find – next to the DC input – trimmers to attenuate all the CV in- and outputs of the pedal. You can easily set the sensitivity of the sensor and the output voltages of the Gate Speed, Gate Amount, Delay Time and Delay Feedback CV inputs.

Knobs, Switches, Sliders and LED’s

• INPUT GAIN – slide control which allows the user to set the input gain of the plugged in instrument or line audio signal, 0 to +20dB variable gain.
• DELAY BLEND – slide control to set the amount of processed delay signal within your overall sound from completely dry to completely wet.
• GATE SPEED – rotary control to adjust the speed of the gate.
• GATE AMOUNT – rotary control which adjusts the amount of the gate signal applied to the audio input signal, going from not influenced at all to amplitude modulated to completely gated.
• CYCLE – rotary control to adjust the amount of processed signal fed back into the signal chain. Going from no signal being fed back to ‘usual’ feedback sounds creating overtones and/or karplus effects to going completely nuts with feedback.
• DELAY TIME – rotary control to set the delay time. Please note that the delay chip used in this circuit was never meant to go anywhere near the settings between 6 – 10 where serious bitcrushing like effects and other odd sounds start to appear.
• GATE SHAPE – 3 pole toggle switch to switch between the 3 different shapes of the gate: ramp, pulse and sawtooth.
• GATE RANGE – 3 pole toggle switch to switch between high, mid or low speed range for the gate.
• GATE SPEED LED – indicates the speed and shape of the gate clock.
• EFFECT ON LED – indicates if the effect is switched on or bypass.
• FOOT SWITCH – Heavy duty Alpha foot switch. Turning the effect on or off.
• 2 IR EMITTERS, 1 IR RECEIVER – calculates the distance between an object and the pedal and generates a CV signal according to the measured distance. The CV output of this sensor appears as a CV output on the patch bay from where you can route it to the CV input of your desired, to- be modulated feature.

The In’s and Out’s of the Patch bay

• AUDIO IN – plug your sound source here.
• AUDIO OUT – listen to what you created here.
• CYCLE OUT – you can grab your processed signal here before it is being fed back into the circuit here. By sending this signal into external effect units (e.g. filters or EQs) you can change the sound being fed back into the pedal through plugging your externally processed sound into CYCLE IN.
• CYCLE IN – by plugging an externally processed sound into this jack you break the internal CYCLE circuit, thus being able to change the feedback sound in any way you desire.
• CYCLE IN – CV input to control the amount of (internally or externally) processed signal being fed back into the circuit.
• SPEED – CV input to control the speed of the gate.
• AMOUNT – CV input to control the amount of gate being applied to the plugged in signal.
• EXT. GATE – CV input that allows you to control the gate by external gate and/or CV signals.
• DLY TIME – CV input to set the delay time.
• SENSOR – CV output of the onboard motion sensor for usage with CV inputs on the pedal, other KOMA Elektronik pedals or other voltage-controlled devices.
