A 909 kick drum clone you can build! (BETA)

YouTube Published on Aug 24, 2012 by hexinverterDOTnet

"This is a clone of the 909 kick / bass drum that I have been working on. It is able to be built with common parts, or with the rare 2SC/2SA transistors originally used in the design (room for both is on the circuit board)

APOLOGIES for the poor audio. My speaker cones are "fluffing" and my cell phone camera's mic REALLY accented that sound. The kick itself is nice and clean sounding, of course. I will be sharing some directly recorded sound samples soon!

I have added trigger input conditioners and some basic things to make it play nice in an analog modular synthesizer system. None of the original voicing circuitry has been altered.

I will have circuit boards available in my webstore soon: http://www.hexinverter.net

A build guide and modification guide will accompany the project.

909 Kick Clone Noise Generator Comparison

Published on Aug 24, 2012 by hexinverterDOTnet

"Here I demonstrate the sonic difference between a microcontroller-based white noise generator, and the CMOS based noise generator designed by Roland for the TR-909 analog drum machine.

I hope the difference is clear in the video...apologies for the poor quality. I will do some sound samples later as well.

I am working on a do it yourself 909 kick / bass drum clone you can buy a PCB for and build yourself.

PCBs will be in stock at: http://www.hexinverter.net in a few weeks!"
