I learned about this hack on Eddy Bergmans page : Here My psu has a 5V rail and I soldered 3 1n4148 diodes in series to drop 2V to the 3V the tuner needs to function. When you turn on the system mine doesn’t turn on automatically. But pressing the button 3 seconds turns it […]
I can tell you this VCF is one dirrty VCF. It works but you can’t even compare it to any MS-20 build. But it has a ton if resonance. This is the original post: Here
It has a slide function that can be used with external cv or configured with a knob. A rotary encoder changes scales. Other than that it just quantizes incoming CV and pretty accurate at that. The 12-bit DAC is enough for my purposes. Link to original project page: Here #define ENCODER_OPTIMIZE_INTERRUPTS //エンコーダノイズ対策 #include <Wire.h> #include […]
The Kick module hagiwo designed is pretty neat, it sounds compressed and can be pretty dirty. It was my third hagiwo build and it was pretty straight forward. You get a couple of knobs to manipulate the sound: frequency, harmonic, decay, attack. #include <avr/io.h> //———basic waveform make——————– unsigned int frq = 60000; //frequency float duty […]
I found this module on reddit and really liked the youtube video I can’t find right now but there is a github How to make this any better? So far I had no problems with the build BUT there some output and input protection missing imo. Maybe attenuate too hot signals going in? Idk. But […]
This is one of my own modules and by far the simplest. I built it because I wanted logic gates for my CV and I have to say it works nicely. The AND gate has two inputs and one output, the OR gate has three inputs and one output. Both are based on diode logic. […]
This VCO has two oscillators. They can be tunes seperately. The theid knob is for changing the waveform (noise, saw, tri, sine, square) It takes a 1v/Oct signal for the pitch and has an octave switch to set it one octave higher or lower. Link to original project page: Here Everything works fine, but the […]
This Mozzi based Arduino VCO sounds really great. Link to the original project page: Here Hagiwo’s code: Important to note is that you’ll need the MOZZI Arduino Lib to get this to run. #include <MozziGuts.h>#include <Oscil.h>#include <tables/cos2048_int8.h> // table for Oscils to play#include <mozzi_fixmath.h>#define CONTROL_RATE 256 // Hz, powers of 2 are most reliableOscil<COS2048_NUM_CELLS, AUDIO_RATE> […]
The layout I use is based on LMNCs design, but I found that he put up some extended designs on his page: Here Info: Sadly I don’t have a schematic for this build. If I get around I’ll try to draw one.
This module like the other has a lot of uses.
