Hi everyone,
I've been working on a little project to scratch a personal itch called the kxmx_bluemchen. It is an open source, 4HP, Eurorack module powered by the Electrosmith Daisy Seed, and I've decided to make a handful of them.
The Daisy Seed is an embedded DSP development platform with an ARM Cortex-M7 MCU, High fidelity AKM stereo audio codec with up to 24-bit 192kHz, 64MB of SDRAM, and 8MB of flash memory. The Daisy Seed is a formidable platform which already powers a number of reputable Eurorack modules such as the Electrosmith Daisy Patch, the Qubit Surface, and the entire Noise Engineering Versio series.
The kxmx_bluemchen is a fully open source hardware design that attempts to expose as many capabilities of the Electrosmith Daisy Seed as possible, while remaining a compact 4HP wide. It features:
- 1 rotary encoder with push-button function
- 1 64x32 pixel OLED display
- 2 potentiometers
- 1 MicroSD card socket
- 1 MIDI TRS input
- 2 CV input
- 2 Audio input
- 2 Audio output
These hardware features can be used, in combination with the open source software libraries, to create the module that's in your head.
Being built on the Electrosmith Daisy Seed, this module leverages the open source libDaisy library for simple, intuitive access to the hardware features.
The DaisySP library provides you with a rich selection of curated DSP building blocks such as:
- Synthesis Methods: Subtractive, Physical Modeling, FM
- Filters: Biquad, State-Variable, Modal, Comb
- Dynamics: Compressor, Limiter, Crossfade
- Effects Processors: Reverb, Delay, Decimate
- Utilities: Math Functions, Signal Conditioning, Aleatoric Generators
If C++ is not your thing, I'm working to make kxmx_bluemchen available as a target for oopsy - Which will allow you to export Max Gen~ patcher to the kxmx_bluemchen hardware.
The kxmx_bluemchen is available as a built module or a DIY kit
So now that I have all the orders for parts out and I’m waiting for them to arrive, I'm going to start taking requests. I’ve put up a website and a registration form for those of you genuinely interested in buying a DIY kit or a module. I’m selling 10 DIY kits and 10 modules and will be handling requests first-come-first-serve. There’s a very good chance I won’t be making any more after this, so grab one now if you want one.
