Introduction
The DIY synth kit is a low cost DIY kit to build a full-fledged analog synthesizer. The kit is
made of an assembled and tested pc board that includes all that is necessary to build a
standard analog synthesizer:
VCO:
• Sawtooth output
• Rectangle output (with variable pulse width)
• Four frequency CV inputs (1V/Oct)
• Summing frequency CV input (to extend the number of CV inputs)
• Two PW/PWM CV inputs
• Summing PW/PWM input (to extend the number of PW/PWM CV inputs)
• Linear FM input
• Hard sync input
VCF:
• Multimode filter
• lowpass, highpass and bandpass output (optional low-notch-highpass with external
potentiometer)
• 12dB/oct slope
• Two frequency CV inputs
• Summing frequency CV input (to extend the number of CV inputs)
• Audio inputs
• Summing audio input (to extend the number of audio inputs)
• Manual resonance control
• Resonance up to self oscillation
VCA:
• Exponential control scale
• CV inputs
• Summing CV input (to extend the number of CV inputs)
• Two audio inputs
• Summing audio input (to extend the number of audio inputs)
• Audio output
ADSR:
• Connections for attack, decay, sustain and release controls
• Connections for range switch (3 ranges)
• Connections for LED display
• Gate Input
• ADSR output
LFO:
• Connections for frequency control (optional different controls for up/down time)
• Connections for range switch (3 ranges)
• Connections for LED display
• Triangle and rectangle outputs
Slew Limiter:
• Connection for slew control
• Input
• Output
Inverter/Mixer
