New ZynthianOS version: stable-2211

It’s been a long way, but finally, the new version of ZynthianOS is here and its called stable-2211. Many things have changed, so be prepared to enjoy with the new features.

Here is the link to download the SD image:

We strongly recommend you to download and burn the new SD image. Trying to upgrade from previous stable versions is a long and error prone process so we have decided to block it to avoid people’s complains. Old stable versions can’t be upgraded!

Regarding changes, the biggest one is the new mixer screen that totally replaces the old layer list screen, but the list of improvements and fixes is huge. These are the more important ones:

New Zynaptik-3 module

Hi @zynthianers!

We just released a new version of the zynaptik module:

and this time it comes in 3 flavours:

MIDI: 3 x MIDI ports (IN/THRU/OUT). Nothing more. It’s the right choice for people buying v4 kits that already include the Zynscreen display and don’t need the extended options.
Standard: adds 16 x GPIO (MCP23017) and include 4 x JST-SH connectors for connecting the official v4 controllers (encoders with switches). With this, now you can build your custom zynthian using v4 parts and the display you like more. The 40 pin “zynaptik” connector is also there, 100% compatible with versions 1 & 2, so you can use the GPIO ports as you like: connecting the zynface module, adding custom switches, etc.
Extended: adds 4 x analog inputs (ADS1115) & 4 x analog outputs (MCP4728) that can be used for CV/Gate, etc. The “extended” version is similar to the older zynaptik-2 module, but adding 4 x JST-SH connectors for the encoders.

ZynADAC v1.0: an Open Hardware soundcard for Zynthian

We are proud of present to all of you the new Zynthian’s official soundcard, the ZynADAC v1.0, an open hardware soundcard for an open hardware project.

The new ZynADAC has the same features you are used to because it uses the same DAC/ADC Burr Brown chips, powered by 3 ultra low-noise voltage regulators (LDOs) and synced by 2 high-stability oscillators, which guarantees the lowest noise & jitter. Also, it’s fully compliant with the RBPi HAT specification.

Outlet 2021: Zynthians with history

For first time, we are offering some old, rare & historic units from our lab and store.

Walking the road of developing a project like zynthian is a funny thing, but you end owning lots of zynthians. Really! Lots! And you love all of them because they are part of the project’s history, and you love the project, so you love the zynthians and the history behind every one of them, etc.

Interview with Ragnar Jón Ragnarsson from Urmull&Kradak

Jofemodo: Why do you exist? (Urmull&Kradak)

Ragnar: Urmull & Kraðak is a cooperation art project between two friends that have been playing music for 20 years but have not until now started playing as a duet. We found the time and mental space to start composing and releasing last autumn. It was soon clear that there was an EP on the horizon. We have been so lucky to be able to get a lot of talented artist to help us, musicians and artist.

New Zynthian Kit v4

Were you awaiting for it?

More CPU power than ever: Designed for the Raspberry Pi 4
Zynductor Passive Cooling: 100% silent!
4 x extra push buttons, totally assignable to functions or programs.
2 x Balanced Audio Inputs with adjustable gain (-12db to 32dB)
Very easy to mount! You don’t need to solder anything. Just plug the wires and tighten the screws. So easy that your grandma could do it for you!!
UPDATE: Kit v4.1 is out and it features Balanced Audio Output too!!

How do you transport your zynthian?

We are very proud to introduce you the new Zynthian Suitcase!

It’s been designed with lightness & robustness in mind. It fits perfectly the v2 & v3 aluminum cases and it’s built with Oxford 600D Polyester and high density EVA foam.

New Zynthian Kit V3

Just plug the wires and tighten the screws!

I’m really proud to present the new Kit V3, a big step forward for the Zynthian project because of several reasons:

Pre-built: It’s completely pre-built using SMD technology, so you don’t need to solder anything. Just plug the wires and tighten the screws.
Zynscreen: The new official display has been specially designed for zynthian and integrates the controller interface, what simplify the assembling process.
Zynaptik: The new zynaptik circuit integrates the 3 standard MIDI ports (IN/OUT/THRU) and some new optional features.
Audio Input: The Hifiberry DAC+ ADC is the new official soundcard and integrates audio input, allowing to use zynthian as a powerful FX processor or stompbox.

We have a dream. We want to empower musicians with upgradable and easy-to-maintain machines that can be used on stage and studio. Open machines that can be used for “normal” tasks, as playing and composing, but also can be extended and hacked for going beyond that, for exploring new spaces.

The new Raspberry Pi 4

Yesssssssssss!! The new Raspberry Pi 4 is here and it brings us more CPU power and more memory, and this is definitely good for Zynthian Project. Audio synthesis and processing are hungry tasks 😉

But i don’t like everything on the new RBPi-4…

New Zynthian Kit V2+: Audio Input is here!

WARNING: HifiBerry as recently changed the specification for the DAC+ADC. It seems that the balanced input is not working as expected and it’s been removed from the specs. The new HifiBerry DAC+ADC PRO includes a true balanced input among many other improvements.

We are very proud to present the Zynthian Kit V2+, the new official flagship, featuring the amazing Hifiberry DAC+ADC as soundcard.

As you may note, the “ADC” (Analog/Digital Converter) in the soundcard’s name announces the difference: the new official kit now has audio input and yes, this makes a big difference!
