midi-out-for-a-vintage-korg-cx-3-organ

[Michael] loves this old organ of his, but recently he wondered if it would be possible to add MIDI out without altering its original functionality. With a bit of research and more than a bit of hard work he accomplished his goal.

The nice thing about working on a quality piece of hardware like this is the resources you … Read the rest

Programming an Arduino using an audio file

This proof-of-concept is just waiting for you to put it to good use. [Mike Tsao] wrote an Arduino sketch that lets him decode incoming audio data which could be used to program the device. He’s calling the project TribeDuino because it decodes an audio file which is actually the firmware update for a Korg Monotribe.

Earlier in the month [Mike] … Read the rest

Reverse engineering a Korg Monotribe

Yesterday, Korg released a firmware update to their ribbon controller synth, the Monotribe. The firmware is just an audio file that needs to be played to the sync input of the box. [gravitronic] thought this was rather interesting, so he decided to decode the monotribe firmware. It’s the first step to custom Monotribe firmware, and on the path towards … Read the rest

Adding a Compact Flash reader to a Korg Triton

[Roberto Barrios] has a Korg Triton sampling keyboard which he enjoys very much, but has grown tired of using media of yesteryear to store his work. He had the option of floppy disk or Jazz drive and for a time he was using a floppy-to-USB emulator, but the keyboard still insisted on a 1.44 Mb storage limit using that method. … Read the rest

Archaeopteryx: a large, colorful MIDI controller

This is [Robert Jarvis'] new MIDI controller which he has christened the Archaeopteryx. It makes its home (quite nicely might we add) in a discarded wooden cutlery case. This provides a strong and stable base for the controls while keeping the electrical connections close at hand for any rewiring or repair work.

The interface is made up of several … Read the rest

Monotron Openly Monophonic

Famous synth manufacturer Korg has released the schematics (get them here if you don’t like to fill out forms) for their wee little Monotron for all to see and use! This is great news for anyone looking to build up a synth from scratch or to circuit bend their existing monotron. The filter circuits alone would be fun … Read the rest

Extreme piano transplant

We always wondered what happens to ancient pianos when the internals can no longer be kept in a playable condition. [Jean Philippe Roch] gutted his elderly upright and fit a Korg Triton inside. After the break you can watch a few videos including a slide show of the work log.  [Jean] separates the Korg keyboard from its case and … Read the rest
