godinpants Covers little-scale's 'Come Back To Me'
For the recent Sound Bytes show in Melbourne, Sydney chipper godinpants played a cover of my track 'Come Back To Me'. Listen to the cover here. Listen to the original here. I am told that a live version will surface soon (maybe), so stay tuned.

little-scale Live at AVCON 2011, July 23rd
I am playing at this year's Game Night, which is part of AVCON2011. Game Boy musician xandox and DJ DK81 are also playing. Come along for some super fun happy times.
When: July 23rd from 6pm onwards
Where: Adelaide Convention Centre, Video Games Hall
Cost: $5 (free for AVCON ticket holders)
I'm so excited that I will be writing some new NES music for this event.

VecM: DIY MIDI Interface for GCE / Milton Bradley Vectrex
Introduction
The VecM is a MIDI interface for the GCE / Milton Bradley Vectrex console. The VecM is made up of two main parts - the interface hardware (which includes a pre-programmed microcontroller) and a custom program for the Vectrex console (which can be put onto a homemade cart or a third-party flash cart). The VecM interface gives the user full control over the sound capabilities of the Vectrex sound chip.

Vectrex Sound Capabilities
Unlike most video game consoles, the Vectrex has no direct audio line output and was designed with an internal speaker only. As such, the sound of the Vectrex is always coloured by the physical space in which the console is used. This colouration can be bypassed by modifying a Vectrex console so as to have a direct audio output.
The Vectrex features an AY-3-8912 sound chip – a programmable sound generator made up of three channels. The AY-3-8912 is a sonically identical variant of the AY-3- 8910 sound chip, lacking one of the input / output ports found on the latter. Each channel of the AY-3-8912 can be set to a pitch-enabled mode for which the frequency is selectable. The sound chip also features a noise-enabled mode whereby a global pseudo-random noise source is routed to the output of a given channel. The frequency of the noise source is selectable via a global register. These two modes are not mutually exclusive, as a channel can simultaneously output both pitch and noise material.
The frequency resolution and frequency range of the AY-3-8912 are beyond that of comparable sound chips, such as the Texas Instrument SN76489. However, as with the SN76489, the oscillators of the AY-3- 8912 cannot be adjusted in terms of duty cycle and waveform type. Furthermore, the sound chip features a single amplitude envelope generator that can be used to modulate the volume of a channel. Although all of the features of the AY-3-8912 can, in theory, be used for music composition with the Vectrex, original Vectrex games tended to feature sparse soundtracks that under-utilised the capabilities of the sound chip.
Interface Hardware: Schematic and Notes
9 Pin D-subminiature 1 and 2 refer to controller ports one and two of the Vectrex video game console. IC1 is the ATmega328 microcontroller loaded with an Arduino bootloader and Vectrex Music Interface firmware.

Interface Software: Vectrex Software
There are two main software components to VecM - the program for the Vectrex console, and the program for the Arduino platform (or compatible microcontroller).
The ROM for the Vectrex console can be found here:
http://milkcrate.com.au/_other/chipmusic_software/vecm/GCE%20Milton%20Bradley%20Vectrex%20ROM%20for%20Console.bin
The source code for the Vectrex ROM file can be found here. Please note that the source code for the Vectrex ROM file is not required for the VecM:
http://milkcrate.com.au/_other/chipmusic_software/vecm/GCE%20Milton%20Bradley%20Vectrex%20Source%20Code%20for%206809.txt
The source code for the Arduino platform can be found here:
http://milkcrate.com.au/_other/chipmusic_software/vecm/GCE%20Milton%20Bradley%20Vectrex%20Arduino%20Source%20Code.txt
To run the Vectrex ROM file on an actual Vectrex console, a flash cartridge (e.g. http://www.vectrex.biz/) or homemade E/EPROM or similar cartridge is required.
To run the Arduino program, simply copy and paste the source code into a new Arduino sketch, compile and upload to the microcontroller board as per usual.
