• Power: 4 X AAA.
• Audio out: 1 stereo output line level can drive a headphone.
• Mono jack: input or output for cv/gate/audio signals (max 10v pp).

Getting started:

All connection can be connected anywhere you want but some send signals and some receive them. Its best to just try and see whet happens, this way you find out while playing with it.. good luck :-).

p.s. On every page there is a big hole in the corner, this is for the patch cables to go thru.

Page 1:

Pots:
• left pot: base kick, left is no base kick, right increases the speed.
• middle pot: base kick, left is no oscillator, right increases the pitch.
• right top pot: oscillator the can be connected to via the header.
• right bottom pot: volume of page.

Buttons:
• left top switch: connect base kick to cv input of audio oscillator on this page.
• left bottom switch: ???.
• right top/bottom switch: connector oscillators of the audio oscillator to itself to make distortion effect.

Header (text is on page 2):
• 40106: CV input audio oscillator.
• 40106: CV input audio oscillator.
• T-Kick: kick input.
• 74hc14: gate out of oscillator.

DIP:
• 1: 74hc14.
• 2: T-Kick.
• 3: 74hc14.

This is the backside of page 1.

Page 3:

Pots:
• top left pot: delay length.
• top right pot: delay speed.
• right top pot: starve of audio oscillator.
• right 1 down pot: control of 1 oscillator of the starving audio oscillator.
• right 2 down pot: control of 1 oscillator of the starving audio oscillator.
• right bottom pot: volume of page.

Header:
• 4017: output of one of the leds of the water fall.
• LDR: CV output of the LDR.
• pt2399: CV input for the delay chips speed.
• 4017: output of one of the leds of the water fall.
• 74hc14: CV input for starve of the audio oscillator.

DIP:
• 1: 4017.
• 2: 74hc14.

Page 5:

Pots:
• right 1st (top) pot: 74hc14 LFO oscillator speed.
• right 2nd pot: volume Tom sound.
• right 3rd pot: volume Piezo sound (for music box).
• right 4th pot: head volume (theremin type operation)

Header:
• 74hc14LFO: Output of oscillator.
• 74hc14invLFO: Output of oscillator inverted.
• Tom-Hig: trigger input for tom high sound.
• Tom-Mid: trigger input for tom mid sound.
• Tom-Mid: trigger input for tom mid sound.
• Tom-High-CV: CV input for tom high.
• Audio-Out: connection to audio out mixer.
• LDR+: ldr cv output.

Turn knob:
• The big turn knob winds up the music box (the music box is made to sound not as it supposed to by switch comb with another music box and putting it back not strait).

DIP:
• 1: Tom-Mid.
• 2: 74hc14invLFO.
• 3: Tom-High.

Page 7:

Pots:
• Master volume output potmeter.

Header:
• 1: Connects to DIP switch 1.
• 2: Connects to DIP switch 2.
• 3: Connects to DIP switch 3.
• IN: trigger input for tom mid sound.

Switch:
• Power switch.

Sockets:
• Top socket: can be used as input and output for external signals (the input is protected by clipping diodes, dont take ait to far thou).
• Bottom socket: stereo output jack that outputs two times mono signal of the synthesiser.
