Notes: 'Beast's Chalkboard' is dual channel stepped voltage source and adder for your eurorack modular synthesizer system. It primarily is intended as a dual octave switcher for VCO's but has many other uses including sequence transposition, FM ratio creation, buffered CV distribution and VCO calibration.

Technical Specifications:

Supply: +/-12V (Reverse voltage & polyfuse protection)
Current Draw: ~30ma
Size: 6 HP
Depth: 22mm (including power header)
Offset Error: +/- 10mV

Notes: The 333 is a summing and distribution module for Eurorack modular systems.

It is composed of three identical sections, the red, yellow and green, each of those featuring three inputs summing amplifier with three independently buffered outputs.

Derived directly from the CGM creative mixer series, the sum section is DC coupled, allowing the sum of control voltages as well as audio signals.

With an extremely low tolerance in both sum and output sections, it is suitable also for summing quantized voltages like the ones coming out from the quantized outputs of the SAPEL.

In case CVs or audio signals are particularly hot, the 6dB attenuator might be helpful to reduce exactly by 50% the incoming signals.

Red and yellow output are also normalled to the 1st jack socket of the yellow and green input: in this way this module can also work as a 1 to 9 buffered multiple.

Notes: A (buffered) mult is an essential item in every rack. This buffered DC-coupled module will fulfill all your audio and CV multiplying needs.

With a little switch on the back the module can be configured in two different modes.
The 1-to-8 mode speaks for itself, offering eight identical copies of your input signal.

The double mode offers a 1-to-4 and 1-to-3 buffered multiple with the first input getting normalised to all output jacks if the second input stays unused.

Notes: In recent years, stereo signal paths have increasingly found their way into the wonderful world of Eurorack synthesis - so naturally, utilities should follow suit. Introducing the Herzlich PSA, a simple solution to a problem you might not even realize you had. Far from just useful as an attenuator for audio sources in mixdowns, the PSA can also be used to bring audio down to more managable levels (such as line level), attenuate multiple signals simultaneously (like increasing the modulation depth of two LFO's at the same time! It's like having two hands, but with one hand!) and even function as a multiple: Attenuator 1 is normalled to Attenuator 2, so multing your stereo signal (or two mono signals) while attenuating the two signals individually is easy as pie.

There's not much else to say, except that it's passive, and draws no power - and it looks great!

Notes: Octo I/O is a bi-directional passive Polytip to 3.5mm expander and a Polytip Mult. The expander section lets you break out to each individual voice from a polyphonic module. The mult section lets you mult Polytip polyphonic signals from one source to multiple destinations. For example patching the OCTOSTAGES envelopes to control both your OCTOPASS filters and HEXAGAIN VCAs.
