Elmyra is a platform for sonic exploration inspired by the widely beloved Lyra-8.

Elmyra is based on the Adafruit ItsyBitsy M0 Express microcontroller. Its 10-bit audio resolution already gives it a wonderfully gritty sound, and this circuit adds some nasty analog distortion to it. The synth runs on USB power and you can easily build it yourself or buy an assembled one.

All information needed for a full DIY build can be found below. If you want to purchase, these are the options:

  • v1.3 full kit including everything needed to built, also the bamboo case:
    • If you’re within the EU, you can order at Exploding Shed.
    • If you’re in AUS/NZ, you can order at Elk Elektronik.
    • If you’re anywhere else, kits are also available directly from me for 150 € (no VAT).
  • v1.3 assembled unit:
    • If you’re in North America, you can order from Perfect Circuit: Neutral Labs at Perfect Circuit
    • Assembled units are available directly from me for 270 €.
  • v1.3 panel (choose white/silver or black/gold): 20 €
  • v1.3 PCB: 15 €
  • v1.3 panel/PCB/touchpad set: 45 €

For direct orders, send the payment by Paypal to admin@neutral-labs.com and include your choice of panel colour and address for shipping (shipping is 5 € within Germany, 10 € within Europe, 15 € overseas). If you don’t have Paypal, contact me for bank details.

Whether you build or purchase it, you may be interested in the PDF manual.

If you have a panel, PCB or kit, you can refer to the build documents to complete your build (check the version number on your PCB):

If you want to mess with the code (you don’t have to as the microcontroller that comes with the kit is preprogrammed), find it here.

If you want to etch the PCB and create the front panel yourself (only available for v1.1), you can download the PCB and front panel design (220 by 140 mm). Here’s the v1.1 PCB schematic for reference.

Drop me a message if you have any questions. And please share photos, audio and/or video of your creations: admin@neutral-labs.com

If you enjoyed this, feel free to buy me a coffee, but I don’t mind if you don’t. I’m just doing this for fun.
