"Using the Synthesizers.com Q130 Clipper/Rectifier module to show how it is useful for sound shaping on my modular synthesizer.
This module is one of the most under-rated modules in the Arrick Robotics lineup. The ability to thicken the simplest waveform like a single sine wave in this demonstration is one example."

An arpeggiated theme

YouTube via attorks

"The first theme with the Waldorf Q Keyboard. At first you hear the sequence from the Synthesizers.com Modular driven by row 1 of the Doepfer MAQ16/3. After that the volume is raised for the sequence from the self built Modular driven by MAQ's row 2. Then the arpeggiated sound of the Waldorf Q Keyboard, which is MIDI synchronized from the Doepfer MAQ16/3, comes in. This arpeggiated sound reminds me somewhat of the 'Black Noise' album by 'FM' from some 30 years ago, for example the track Aldebaran. The strings are performed by the Clavia Nord Lead 1 and the solo is played on the Korg 900PS. I had to shorten the video somewhat because of the YouTube limit of 10 minutes. The original video can be seen or downloaded from my website after 12 april."
