Highly Liquid

Michael Una looks at using the $44.95 Highly Liquid MD24 MIDI decoder kit to control a handmade analog bass line sequencer and drum machine via Ableton Live.

This video documents modding a Yamaha CS01 with a Highly Liquid Midi mod.

The kit was shipped quickly and was easy to put together. For those of you that have a CS01 and are handy with a solder iron I highly recommend the conversion.

Here’s the details on this bizarre little circuit bent noise jam, featuring and Electronic Wind Instrument and a bent Speak and Math used as a MIDI synth module:

The akai ewi 3000 uses control voltages and has an all analog signal path with it’s dedicated module.

In this example the ewi 3000m module sends midi to the speak and math as well as control voltages brought to the surface of the 3000m on banana jacks. the banana jacks are sent to a cv control box which is essentially a foot switch box with various logic functions and and open ended patchable interface. ewi controls overall pitch of the speak and math based on pitch fingering cv output in conjunction with octave key cv output.

The midi is a retrofit kit available by highly liquid and accesses the speak and math’s rom by triggering key commands. this modification gives the user a wealth of circuit bent sounds accessed by midi note triggering. the speak and math’s output is sent back to the 3000m’s analog amplifiers and filters via breath control on the ewi. there are various note sustain loops and a photo theremin available on the surface of the speak and math via stomp switches. the stomp switches activate leds to indicate on/off. also a big knob with a rubber boot that can be played with the feet.

This is my first run through of my speak and math cv midi synth

The construction and installation of the Highly Liquid MIDI2600 MIDI interface board into a fully functional Atari 2600.

Features:

• Translates incoming MIDI notes to joystick or keypad control signals for any Atari 2600 console
• MIDI-controlled Select & Reset outputs
• Powered by game console—separate power supply not required
• User-selected MIDI input channel
• Power and activity LEDs
• Compact size: 83 x 57 mm (3.25 x 2.25″)

The adapter is about $40. 

The soundtrack is composed and performed on the Atari through the use of a Synthcart cartridge.

This is a short demo of a classic Ace Tone Rhythm Ace Drum Machine which has been modded with MIDI trigger capability.

It’s being triggered by an Oberheim DX ‘a’ (the ‘a’ was the last DX model made by Oberheim and featured stock MIDI), running a few simple patterns.

The Rhythm Ace has about 9-10 drum sounds, most of them are made using resonant transistor oscillator circuits – all the transistors are Germanium – with inductors. There are no IC’s anywhere within the Rhythm Ace (well, now there is with the MIDI board).

The MIDI board is made by Highly Liquid and is actually intended for use in the Atari 2600.
