PLD music Synthesizer

This page describes my very first digital synthesizer, created with a Xilinx XC 3000 PLD (later a XC 4000) almost 20 years ago. It had one polyphonic channel only and 3 individual voices altogether, which could be mixed.

I wrote all documentation at that point of time in german writing language so do not feel disturbed a bout this.

The Synth contains 3 indentical modules of a VCO/LFO-submodule below:
