Ginko Synthese - Seeds

Product information "Ginko Synthese - Seeds"
The SEEDS is a complex powerful 8 bit oscillator and can be used as a complete synthvoice.

On the sound-design side you might notice some 90's popular music influences. There are two reasons for that. First of all; those sounds are a natural match for the rather modest (8 bit, 16MHz) Atmel chip on the Arduino Nano we're using. That music was made using digital synthesizers using the processors available at the time, and those had to make the most of the chips available at the time, which were quite comparable to the Nano. The second reason is that those sounds are a lot of fun. Once that link became clear it became more a of a guiding principle than a potential problem; it seems more sensible to lean into such links than it is to resist them.

The Arduino in the SEEDS kit is already programmed, but in case you need to re-install the firmware you need the Arduino IDE installed on your computer and install the CH340 driver to communicate with the Arduino Nano. The latest Arduino IDE can be downloaded from the Arduino website: The CH340 driver can be found here:

The firmware will be updated regularly so you might want to keep an eye on it to get fresh sounds in your SEEDS every now and than.

• The original “Grains” sound. Two triangle-wave formant peaks synced by the main oscillator. The “mod” knob sets a formant peak.
• Triangle wave with wave-wrapping. The “mod” knob sets the amount of wave-wrapping.
• Super-saw, featuring three detuned saw waves with a PWM feature modulated by an LFO.The “Mod” knob controls the LFO rate.
• Classic FM; a “carrier” sine wave phase modulated by a second sine. The “mod” knob sets the modulator wave’s pitch offset.
• Saw-wave with hard-sync.
• Phase-distortion
• Tuned noise
• Square wave with pulse-width modulation and built in LFO. The “mod” knob controls the LFO rate.

Manufacturer "Ginko Synthese"
My name is Jan Willem Hagenbeek and I am the driving force behind Ginkosynthese. As an electronic musician I have firsthand experience with the gap between the feel of playing live on stage and the more controlled environment when working in the studio for productions. Therefore all of my products are designed with a focus on the immediacy of live performance, but of course they can be easily integrated into a studio environment. Although I am a graduated architect I now only design and build musical instruments and cases. My first music creation steps were made in 1992 when using my parents computer. I started to experiment with sounds and trackers trying to make music which was not easy to put in a certain style. From there I started to experiment with circuit bending and modding which resulted in a range of live acts from 2004 in collaboration with several other musicians and visual artists. My first live solo project (2004) on stage was an atari-controlled orchestra of electronic child toys. Since then more audio-visual projects have been presented on stage. A significant milestone was establishing an electronic musical instruments company Ginkosynthese in 2012. The modules I make as Ginkosynthese have shaped my sound further and I am always searching for new ideas to make non standard musical electronic instruments. As Ginkosynthese is a one man company all orders are processed by myself, if you order an assembled module, I grab my soldering iron and start soldering, if you order a case I make them myself and all kits are packed by me as well... I am not a dropshipping company like Bol or Amazon. While processing orders I try to find my time to work on new projects and I love to welcome people every now and than for a coffee. You can Imagine that I am not always able to ship your orders the next day and assembled modules and cases take longer. Just for you to know if you wonder why you got your order from Amazon in a few days and the order you placed on my website took a bit longer 😉 Oh... And if you are in the neighbourhood don't hesitate to visit for a coffee and a chat, I always love that!
