Fiche technique
- Fabricant : Ginko Synthese
- Modèle : Grains
- Catégorie : Modules générateurs pour synthés modulaires
This complete and easy-to-build DIY kit is one of the cheapest ways to get a voltage controlled oscillator in your modular and sounds completely different than all other oscillators! It can do minimalistic clicks and plops, screaming leads, fat basslines, weird noises or chiptunes.
This is a DIY kit
The kit includes:
PCB
frontpanel
all electronic parts
Knobs and jacksockets
Arduino
powercable
How it works
The sound is a PWM output routed via a low-pass filter and a 10uF capacitor – so no external DAC is required. The low-pass filter on the PCB can be bypassed if you want. Bypassing the filter provides more clarity and a slightly louder output but more artifacts in the sound. There are several codes available here on my website but the codes are highly customizable and I will upload user codes for the Grains from time to time.
PCB version 2 is shipped from 25-06-2015. There has been a change in the way cv input 3 is processed. All earlier codes can be changed to work with V2 and backwards, look for the analogRead (0) in the code and add an extra input for analogRead (3). You can play around with the way they influence each other.
For people who want to dive deeper in coding and want to write a lookup table for 1V/oct tracking, here is how: code doc.
