DIY eurorack modular synth | MOD1 Envelope generator : Arduino based general-purpose CV/Gate

video upload by HAGIWO

"This module is an open source general-purpose CV/Gate module based on Arduino nano.
It can be applied to various CV/Gate modules by changing the program.
There are some performance limitations, but it uses general-purpose inexpensive components.

Envelope generator : 3-output EG. end-of-cycle outputs can be self-patched for use as LFO or clock

New SetonixSynth SkyWave VCO

Feature Rundown w/ Robots Are Red video upload by SetonixSynth

"In this video, Brian aka Robots Are Red breaks down the unique control scheme of the new SkyWave Segmented VCO with audio examples that demonstrate its raw harmonic power."

SkyWave Segmented VCO

The SkyWave is an all-analog voltage controlled oscillator capable of producing many different timbres and unique harmonic behaviors, thanks to an original step-based control scheme which allows the user to dial in completely different wave-shapes and levels for successive oscillator cycles.

The SkyWave uses an internal feedback loop with the clock output of the oscillator triggering a step sequencer which in turn cycles through settings at the frequency of the core oscillator, thus changing the shape and level of the waveform output on a per-cycle basis while also staying in tune and tracking pitch like a typical VCO.

SkyWave Features:

-Complex analog oscillator in 14hp
-Unique “segmented” behavior
-Variable level and waveshape with full CV control and PWM
-Unique “SkyWave” output with sequential waveform control
-Selectable # of steps, clock input and reset for step sequencer
-Audio or LFO output frequency range
-Additional Sine and Clock waveform outputs
-TZFM/TZPM, 1V/Octave and Hard Sync inputs
-Clock division and per-step CV control via Scaffold expander

Technical Specs:
Width: 14hp
Depth: 30mm
Peak Current Draw:
80mA @ +12V, 60mA @ -12V
Input Impedance (All Inputs): 100kΩ
Output Impedance: 1kΩ
