Luminth: Plug it in. Make music.

The Luminth Generative Music System is available for purchase on from now until June 13, 2013.

Click, turn, push+turn. Use the Luminth to generate melodies, percussive grooves, and ambient soundscapes. Make dramatic changes to the music with a single click. Dive deeper to make refined, subtle adjustments. Or let the software work autonomously to create music that morphs over time.



The Luminth is the new product from NTHSynth, a collaboration between Kevin Holland ( and John Staskevich (

Luminth Kickstarter Launches Thursday, May 16, 2013


The Luminth is a minimalist USB control peripheral. To use the Luminth, simply click, turn, and push+turn. The Luminth changes color with the music.

Luminth Orbiter is a generative music software application. Make dramatic changes to the music with a single click. Dive deeper to make refined, subtle adjustments. Or, let Orbiter work autonomously to create music that morphs over time.

The Luminth is the best way to control Luminth Orbiter software, but Orbiter is fully functional with or without the Luminth.

The Luminth and Luminth Orbiter will be available for purchase at 12:01AM EST on Thursday, May 16. Check on Thursday for a link to the Kickstarter project page and purchasing information.

UMR2: MIDI Input and Output for Vintage Keyboard Synthesizers

The new UMR2 (Universal MIDI Retrofit) adds MIDI input/output functionality to non-velocity-sensitive keyboard synthesizers. Use your vintage keyboard as a sound module that responds to MIDI input or as a MIDI controller that generates MIDI output.

The UMR2 is 100% factory-assembled and supports a wide range of vintage keyboards. It supersedes previous HL MIDI retrofit products including the UMR, CS01-MIDI, VL-1-MIDI, and SKM kits. Installation information is being posted at the UMR2 forum by user request. Please join the forum to discuss the installation for your keyboard model.

Example installation guides:

The UMR2 is available for immediate worldwide shipment. For more information, please visit the ordering FAQ.

The NTH was designed by Kevin Holland ( and John Staskevich (

New MSA MIDI Decoder

The new MSA MIDI decoder accepts MIDI input and can control a variety of devices in response to MIDI messages.

Use each output of the MSA-P & MSA-R as you would use an SPST switch.  Use the MSA-T to control a variety of DC loads including solenoids, motors, LEDs, incandescent bulbs, or power relays.

Features of the new design include:

  • Easier programming via optional “learn” method
  • LED indicator for each output circuit
  • A variety of output modes based on user suggestions
  • User-upgradable firmware

MSA MIDI Decoder Update

The MSA MIDI decoder has been redesigned.  The new version will ship in November, and will be available in the familiar -P (photorelay), -R (reed relay), and -T (NPN Darlington) output varieties.

The new design features several improvements, including:

  • LED indicator for each output circuit
  • Configure the unit via SysEx or via a new “learn” method
  • New output modes
  • User-upgradable firmware

The new MSA will ship either fully assembled or “mostly assembled”.  At most, the user will have to solder the output elements, LEDs, and terminal blocks.

Preliminary documentation and other information will be posted at the MSA support forum.

Below are the feature diagram & mechanical drawing for the MSA-R.

MIDI CPU: Instant DIY MIDI Controller

The new MIDI CPU accepts input from switches, potentiometers, rotary encoders, switch matrices and external digital & analog signals.  In response, it generates virtually any type of MIDI message.  Buy now!

The MIDI CPU ships fully assembled.  Simply attach MIDI connectors, control components, and a battery or DC power supply.

Features include:

  • 24 independent input terminals
  • Monitors up to 128 switches, 14 potentiometers, or 12 encoders
  • Allows mixed input types
  • Merges MIDI input with locally generated messages—multiple units share a single MIDI Out port
  • Powered via battery or DC supply between 3.3V and 12V
  • Measures only 66mm x 38mm (2.6″ x 1.5″)
  • Configured via MIDI SysEx message
  • User-upgradeable firmware

The MIDI CPU has a long list of potential applications.  Build your own traditional footswitch, keyboard, or “knob box” controller.  Build your own alternative MIDI controller—optical theremin, fret-based controller, etc.  Generate MIDI note patterns or CC waveforms from digital or analog signals.  Re-purpose a “consumer” keyboard, calculator, game controller, or other electronic device as a MIDI controller.

These possibilities will be explored with “how-to” information at the blog and forums.
