A Visit to Noisebug - Synth Store | Interview

Published on Jan 4, 2019 Under the Big Tree

"I had a day left for my Christmas vacation before having to go back to work, and decided to spend it visiting a store that I had wanted to see for a long time: Noisebug in Pomona, California. Blake, the general manager and I chatted for a long time about all manner of esoteric synths and recording equipment, and then he was kind enough to give us a tour of the space. The results are a deep dive into a retail store that specializes in the finest quality synthesizers, whether Eurorack, 5U, Buchla, desktop, or keyboard. This is a must-see interview for the devotees of truly esoteric electronic music devices.

Under the Big Tree is Nick Peck's YouTube channel, focused on music and sound design equipment and techniques, composition, production and performance of music, modular synthesizers and electronic music in general, and tabletop board games.

Some notes from watching the video: Elby Designs Pixie (EDP WASP synth - note Tinkerbell in place of a wasp) on the obscure front. BTW, Serge paperface refers to the original Serge panels from the 70s that had printed paper on the front panels. Radiohead used Analogue Systems. The power buss differs from Doepfer based eurorack. Ran out of label space with Moon Modular! 10 Year anniversary system featured. The Kilpatrick Audio K4815 Pattern Generator in Buchla format exclusive to Noisebug is featured.

New ACL - VC Dual Amp Eurorack Module

"High quality dual linear VCA with mixing function.

Audiophile Circuits League VC Dual Amp contains two fully discrete voltage controllable
amplifiers with linear characteristic. It is based on a new circuit design which delivers unheard
clarity of sound. To this day there is no other VCA using this special technique!

The module offers a very low harmonic distortion in the whole linear gain range, no crossover-
distortion and no overshoots nor ringing. Furthermore it has a very high dynamic range which

provides a lot of headroom. The VCAs will amplify the input signal very accurately and it will
sound crystal clear, without any coloration, distortion or bleed.

Each channel has a Gain potentiometer for manually setting the VCA's initial gain and a control
voltage input which is equipped with an attenuverter for scaling the modulation.

Thanks to normalized signal and CV inputs, both VCAs can be used in conjunction. - Great for
processing stereo material. Furthermore, you can create voltage controlled panning effects and
crossfades in next to no time.

Beside the two individual audio outputs from each VCA, there is a Sum-output which provides the
mix of the output of both VCAs and of the signal coming from the Aux-input. This additional input
has no level control and is mixed at unity gain. Thus three different signals can be mixed together.
The amplifiers are also suitable for processing control voltages thanks to a completely DC-coupled
signal path.

Behind its simple appearance, this module shines with its functionality and sound quality!

VÖ: early 2019!
Price: to be announced!"

NEW audiophile circuits league (acl) - sinfonion

"acl is announcing the release of the Sinfonion, the most complex and versatile harmonic CV prozessor in Eurorack format created by Mathias Kettner.

Featuring three independent quantizers, a four-voice chord generator, an arpeggiator and a complex chord progression sequencer in one!

Thanks to the 76 control elements it puts an amazing tool under your fingertips, enabling you to play your modular system in a very musical way.

With Sinfonion, you will take the place of the conductor, and your modular system will follow your movements sounding like an orchestra!

42 TE

Release date: Early 2019
Price: 960,00 €"

"Audiophile Circuits League
Welcome to the Audiophile Circuits League. We are a group of musicians and engineers based in Berlin.
We are in the very fortunate position of being able to design and build our own equipment, the kind of equipment we want to use.
Of course, there are many other excellent companies making fantastic equipment – much of which we own and love – and so rather than trying to reinvent wheels, we go beyond classic designs.

First we build devices that avoid problems we’ve encountered – everything from irregular performance to awkward connection placements. And we ensure consistent quality, using only carefully selected component, and assembling our equipment here in Germany.

Second, whenever possible, we try to create modules that do something different and offer new possibilities – be that a filter that doesn’t lose the bass when you crank up the resonance, or a VCO which allows gradual morphing from soft- to hard-sync.

One of the best things about modular is the flexibility and creativity it offers, so if you have any suggestions for new features, revisions, or even new modules, we’d love to hear from you."
