The V5.1 kit is the most advanced kit for building your zynthian and getting a versatile synthesizer, powerful keyboard expander, audio processor, groovebox, sequencer, midi router and much more!
It is easier to assemble than ever. We keep the DIY spirit while lower the barrier so everybody can enjoy the experience of building a powerful, professional-looking device that is designed to last, using high quality materials and easy to repair.
BORN FOR STAGE
The zynthian V5.1 is an excellent keyboard expander, reliable and robust, that you can configure to fit your needs on stage. It's light and small, easy to carry. With the VESA-mount gadget you can attach it to a wide variety of stands.
Zynthian is evolving fast as a groove box and production machine. If you like to be in the cutting edge, with the testing version you will get new features, improvements and fixes almost every week. Join our community, share your thoughts and help us to improve.
The V5.1 kit has been designed for the RPi5, what doubles the processing power from previous version, allowing smooth operation with more synths and effects. This extra power can also be used to run zynthian at higher sample rates (96 KHz) with lower latency (6 ms).

Thermal Block
The zynthian V5.1 kit features a passive cooling system that avoids fans and dust, allowing the CPU to run faster and totally silent.
It consist of a solid aluminum thermal bridge that conducts the heat generated by the CPU to the aluminum case, that acts as a huge heat sink.
It turns the V5.1 into a hot device with a cool brain.
If you like freedom, you may like zynthian. It's 100% open source. Free software on Open hardware. Extremely configurable and fully hackable. Free as in Freedom.
But remember that freedom has a price. Zynthian V5.1 is not for everybody and probably will never be. It's not a finished product nor a mainstream shiny device designed for those who don't want to invest some time learning how to use it.
Zynthian is a complex beast designed to empower musicians who want to control the technology they use. It includes a stunning amount of functionality that solves many use-cases but could also make your head explode. Basic usage is not hard to learn but you need some patience to overcome the learning curve and master the more advanced features. Please, read the docs and ask the community!
