Electrosmith Intros $40 Platform For Creating DSP-Based Eurorack Modules

Electrosmith has introduced a new DSP platform for building high-fidelity audio modules, the Daisy Patch Submodule.

The Daisy Patch Submodule is a DSP platform for Eurorack synthesizer modules. It features a fast STM32 processor, high fidelity stereo audio codec, and enough RAM to allow 10 minute long buffers – all with standard signal levels and conditioning for the Eurorack ecosystem.

Programmers can use C++, Max/MSP Gen~, Pure Data, Arduino, and more. These languages can be coupled with their open source DSP library, DaisySP, for a powerful music synthesis programming environment.

Tech Specs:

  • STM32 processor at 480MHz, 96kHz / 24-bit audio, RAM for up to 10 minute audio buffers
  • Stereo audio IO, x12 ADC inputs ( 16-bit bipolar CV or potentiometer), x2 CV outputs (12-bit), x2 gate inputs, x2 gate outputs, x12 GPIO
  • Flash firmware over USB via open source web programmer
  • Support for SDDMC, SPI, UART, I2C, and USB
  • FCC / CE Tested and Compliant

Getting Started Hardware

Electrosmith the patch.Init(), a 10HP Eurorack module that breaks out all of the Daisy Patch Submodule pins to jacks, pots, switches, and LEDs.

The patch.Init() is designed to let uses get started immediately with the Daisy Patch Submodule.

For developers that want to make commercial modules based on the Daisy Patch platform, the patch.Init() is open source, both in hardware and firmware. So others can quickly build new module designed, using the open source platform design as a starting point.

Features:

  • Eurorack development platform for the Daisy Patch Submodule
  • High Fidelity Daisy architecture: 24-bit, 96kHz sample-rate, 64MB SDRAM, STM32 H7 processor
  • Stereo I/O
  • Utilitarian design, with code-matching front panel parameter names

Pricing and Availability

The Daisy Patch Submodule is available now for $39.95 USD. The patch.Init() is available for $199.

  1. Roland did this with the EFX range but didn’t last more than a few years ???? Even after a price drop to £145, they couldn’t give them away but they were / are excellent, Maybe this could take off again being open source, we are not relying on one gatekeeper anymore.

    1. those guys were pretty power hungry units I these maybe more interesting as you said open source and seeming average power consumption.

    2. I don’t think the Electrosmith modules are open source hardware. If you look at the schematics for this device, they show a “black box” board named DaisyPatchSM. You have to buy their module or reverse engineer it to use it with Daisy firmware.

      1. Probably the idea is design your own board and stick the module into it. but with any MCU you need to understand hardware to really get what you need beyond basic or pre-provided functions. if you can do that you better off learn from scratch how to develop such hardware and firmware instead being locked by one module or platform. This is the issue with many kits, run/build something (pre-made), don’t understand the hardware/firmware/softare, get stuck with something and throw the board in the corner to forget about it.
