Hey all!
Posted this on the programming sub board earlier, but I imagine not everyone takes a look there. Made my first Grains firmware, this is for the lovers of slooooow modulation out there!
Its a voltage controlled sine wave LFO. It goes from an ARBITRARY SLOW frequency up to about 10-20Hz. Default mode is from 0.01Hz tot 10Hz, but it is easy to choose your own minimum and maximum in the Arduino Sketch. I placed the two parameters in the top of the sketch, so even if you have no programming knowledge at all, you can just type in the two numbers you desire
Controls are as follows:
POT1 / CV1: control over frequency, ranging from 0.1Hz up to about 10Hz.
POT2 / CV2: control the amplitude of the sine wave. Note that due to the digital nature of Grains, at small amplitude, there are only a few 'steps' in the sinewave. For higher quality, it is better to attenuate with an external, analog module.
POT3: controls the offset of the sine wave. You can change the center of the sine wave with this knob. If the sinewave hits 0 or 5V this way, it will get topped off.
CV3: this is the SYNC functionality. A trigger or high pulse here will reset the sinewave to its center position & starting going up.
Code is tried and tested by some kind members of the community here! It will run both on AE Grains or an Arduino Nano.
