9. f control voltage CV is not hard to understand Instead of turning a knob on your pedal you simply connect a voltage the control voltage to the corresponding CV input that does the job for you So for example if you want to have quickly varying GATE AMOUNT you don t have to turn that knob all the time back and forth fast until your fingers fall off but simply connect an alternating CV to the AMOUNT CV input You can take control signals from any source for controlling the inputs of the BDIOI All of the CV inputs theoretically accept control voltages from 100V to 100V though a range from 5V 12V 15V to 5V 12V 15V is more common and usable Since the BDIOI is running on a 9V power supply you might wonder how you can use a signal as large as 15V to 15V The answer is simple We provide you with a trimmer for each CV input on the backside of the panel SENSOR SPEED DLYTIME AMOUNT CYCLE Y v 9v 9 E CVOUT ON ON CVIN CV IN 9V DC INPUT i So whenever you notice a significant distortion or clipping in your control signal waveform or strange CV behavior simply turn the trim pot counter clockwise towards the word CN until you hear your desired result By turning it counter clockwise you attenuate the incoming CV signal Fully counter clockwise means that the incoming CV signal is completely gone whereas fully clockwise means that the incoming CV signal is arriving to the circuit unattenuated In additio

14. o bit crushing effect is a side effect of clocking the BBD chips slower than it is actually intended to be see introductory notes about analog delay chips on page 3 Also be aware of the fact that the clock of the BBD chip used in the BDIOI will appear as a function of your input signal sitting on top of your waves We don t consider this as a bug or malfunction but think that whoever is brave enough to turn the TIME knob further than lOOms will either not care about this side effect or love its sound as we do at KOMA Elektronik The second control in the delay section is the knob labeled CYCLE which controls the amount of delayed and amplitude modulated signal flowing back into the delay circuit therefor representing the amount of feedback in the delay circuit Delay Blend The last feature influencing your sound in the signal processing chain is the DELAY BLEND slider You can choose how much of the delay signal is applied to your amplitude modulated input signal The slider is an equal power panning slider which means that you go from completely dry no delay signal at all to completely wet only delayed signal with no gain loss over the whole range of the slider Sensor One of the features on your BDIOI you won t find in any other pedal is the possibility to control the features of the pedals with the on board motion controller Since its working with infra red LEDs we call it the SENSOR The motion controller can be used in
