LE BIDULE, an open source electronic and standalone instrument, is coming soon. It is a proteiform music controller with an analog synthesizer and midi capabilities.

I will soon sell cheap and sustainable instruments (I'm currently testing the last prototypes), but the main purpose would be to teach and encourage people to do their own flavour, design and behaviour, and become Bidule's luthier.

The firmware, which is currently at version 0.97, allows a lot of behaviours (slide string, keyboard, harp, wind... even new ones that you can program by yourself).

Since it has presets and many options, I made a lightweight editor working on Linux, MacOS, Windows and Android thanks to a web browser.
Here it is : BIDULE EDITOR
