Winterbloom Sol
Winterbloom Sol
Sol is a uniquely customizable USB MIDI to CV/Gate module. It's designed to be useful right out of the box but flexible enough to accommodate a ton of different CV/Gate generation needs. It is an unusual module, though- Sol is the first Eurorack module that can be re-programmed using CircuitPython. It's designed from the ground up to be customized by you. You are not limited by what we’ve programmed the module to do and you don't have to become an embedded developer to impart your own magic into this module.
Manufactured in the United States.
In stock, but assembled on demand. Ships in 1-2 weeks.

Sol is a re-programmable USB MIDI to CV/Gate module. It's functionally similar to Mutable's Yarns and Hexinverter's Mutant Brain, but with a little bit of Ornament & Crime mixed in plus some extra magics.
It's unique in that the program it's running is written in CircuitPython and is intended to be edited and customized by you!
How does it work? Well, when you connect Sol to your computer you'll both see both a MIDI device as well as a very small external drive. This drive has a code.py file that you can edit with any text editor and customize how this module works. No complicated developer tools to install!
Specs
8hp
Four 16-bit control voltage outputs with a range of -5 volts to +8 volts
Four gate/trigger outputs
One USB B port (& one nice Chroma USB cable included)
One very pretty RGB LED
+12v 38mA, -12v 6mA
How Sol maps MIDI to CV/Gate
Sol comes with lots of examples, but it doesn't have any strict limits on how you map MIDI data to the eight outputs. If you want to send velocity to CV B, you just add it to the code: outputs.cv_b = state.velocity, if you want to send some CC value to CV C, same idea: outputs.cv_c = state.cc[42] . Sol gives you complete control over how it maps MIDI data to the outputs and you can customize it using the extremely beginner-friendly and approachable Python language. What's even better is that you can change all of this on the fly- you just save the code.py and your changes are immediately applied. It encourages you to experiment and explore the possibilities!
What else can Sol do?
Sol can do everything you'd expect a MIDI to CV/Gate module to do. It can do multiple channels, portamento, polyphony, MIDI clock & transport, etc. Sol comes with examples on how to do most of these common use cases. However, the real power is that Sol is basically a teeny re-programmable computer with CV and Gate outputs. That means it can act as an envelope generator, an LFO, a random CV/gate source, and even more! It comes with some examples on how to do things other than just MIDI conversion.
We have more demo videos coming soon, but in the meantime you can check out John Park playing with the beta in this video:
