DUb STeP ARCADE
ANALOGUE SOUND FX CONSOLE
The dub~Step~Arcade is a analogue sound FX synthesizer featuring both the modulated tone characteristics of the popular DUB~SIREN sound FX unit's and the stepped pitch computer esc tone's of the Atari punk console (stepped tone generator).
Hence the name Dub Step Arcade!

The D~S~A extends the basic principles of the two circuit's adding common synthesizer features such as Voltage control, Attack-Decay Envelope generator Voltage controlled amplifier and LFO Modulator !!.

This project was originally a kit i sold but i NO LONGER sell kits and so i have chosen to let it go public the PCB trace for the project is at the bottom of this page
