OT 1 - Eurorack Oscilloscope & Tuner Modular Synthesizer EcoLab

video upload by EcoLab Audio

"Super handy and useful Synthie-Tuner and an Oscilloscope in 4HP.

The output is a buffered sibling of the input.

The potentiometer adjusts the level of the incoming signal to the scope.

On the mainboard is another tiny potentiometer to adjust the level of the incoming signal to the tuner.

MS20 Filter DIY Eurorack Modular Synthesizer EcoLab

video by EcoLab Audio

"OTA based Filter with low pass, high pass and 3 CV ins.

It´s mostly based on the original schematic with some level adjustments and a switch for the modes.

It does have a very gritty, screamy and unstable character which made it pretty famous.

After about 50% of resonance the madness begins 🙂 It goes into self oscillation but don´t expect proper tuning stability.

It is simply a very experimental piece of gear and if i shuld describe it with some words:

It sounds like a pissed and wet cat 😀

EcoLab Eurorack Module Demos

The above playlist features demos for four of EcoLab's eleven current module line-up. You can find their additional modules at ecolabaudio.de. Playlist:

1. 808 Kick Drum Replica Eurorack Modular Synthesizer EcoLab

It´s a modern approach of the possibly most popular bass drum in electronic music scene.

I´ve been following the original schematics to get the closest result.

As you might remember, there is no tuning knob in the original one. It‘s fixed to 56Hz.

This version goes from 42Hz to 127Hz
