Bit Pirate v2
Bit Pirate is once again a derivative of the original Fruits circuit.Taking the first part with the LM386 but replacing the 4017 with a 4040 and a 4070 to generate 3 octaves of a square waved signal.
Including the distorted LM386 signal, you now have 4 individual volume knobs to blend together your very own ultra thick synth tone.
Bit Pirate v2 User Guide
The pedal uses 9VDC power (2.1mm jack: center-negative).
Triple Bypass:
This pedal uses a unique bypass switching system that I call “Triple Bypass”, where you have three different “modes” for turning the pedal on and off:
- Short Press: Works like any regular pedal. Press to turn it on and then press to turn it off.
- Momentary/Hold: If you press and hold for about 1-2 seconds the pedal will enter a hold mode. Here it will simply stay in the state it entered when pressing down the button, for however long you decide to hold down the button, and then return when you release the button. So if you press down when the pedal is turned OFF it will stay ON for as long as you hold the button pressed down, and vice versa.
- Tap Tempo Bypass: If you quickly double tap the bypass button (either when on or off) the pedal will enter the Tap Tempo Bypass mode. Here the pedal automatically turns itself on/off in whichever tempo you tap. So to change tempo you simply tap a new tempo.
N.B. Bit Pirate v2 continuously counts the time since your last tap. So if you have been in a tempo for some time and give the footswitch another single tap, it will set your new tempo based on the time between the pervious tap and the new tap - upto a maxium length of around 1min.
To exit Tap Tempo Bypass you simply press and hold the button for about 2 seconds. Note that when exiting this mode the pedal will be ON (regardless of if the pedal is in an OFF or ON state).
Controls:
Bit Pirate takes your input signal and splits it into four different voices running in parallel through CMOS technology.
It does this by running your signal straight into a LM386 amplifier, making the signal hot enough to clock a 4040 Binary Counter and also to “trick” a 4070 OR Gate.
This gives us a main voice (LM386), a one octave up voice (4070), a square wave octave down voice and a square wave two octaves down voice (4040).
So each knob on the Bit Pirate is simply a volume knob for it’s corresponding voice. This way you can blend these signals together into a monophonic synthyfied megavoice!
- The top-left “0” knob controls your main signal. A distorted main signal!
- The top-right “1” knob controls your OCTAVE UP volume..
- The bottom-left “-1” knob controls your ONE OCTAVE DOWN volume.
- The bottom-right “-2” knob controls your TWO OCTAVES DOWN volume.
