ADDAC507

This module started with an idea from Rijnder Kamerbeek aka Monotrail, a straightforward random generator with interpolation between random points making it something like a complex, ever evolving, LFO.

The concept is simple. It contains two identical smooth random voltage generators. Each has a frequency, level, offset and curve control. The frequency control sets a steady pace with which bipolar random voltages are generated. The level control works like an attenuator/VCA on the output, reaching from max output to closed. The offset allows shifting the whole wave up and down on the voltage range. Curve determines the shape of the interpolation.The bipolar activity on the main outputs as well as gate outputs are visualised with LEDs.

Both Frequency and Level controls have a CV input with attenuator. When there is nothing patched into the CV inputs, these are internally connected to the main output of the other channel. This normalization makes it very easy to add randomization to the frequency or level for more depth, or of course, add cross-modulation for chaotic voltages.

The output VCAs are usefull to dial in subtle and time-based modulation without the need for external VCAs. For example, to modulate the amount over time with an envelope, or use the other generator with slower speeds to add random changes to the level of a random voltage.

Both generators also have two other outputs. One is an exact inversion of the main output, so it responds to the level and CV input. This is great for stereo or inversed effect patches. The other is a simple pulse output. Here there are two different behaviours: channel A outputs a pulse at every random generation, channel B acts like a comparator. Whenever the main is positive this comparator output is a high gate. And whenever the main output is negative or close to 0, there is no gate output. Great for random triggers or firing other events like envelopes.

A couple other outputs are also available and are obtained by averaging both channel main outputs. The first output is the average while the second is an inverted average.

In case you're wondering: Sure! We can get you a custom coloured front panel for the ADDAC507.
It has an additional cost and takes 4 to 6 weeks to be ready.

At the moment the ADDAC507 standard panel colour is Black.

A custom colour panel can be done in either Red, Green, Blue, White, Silver Gray, Yellowed Silver, and Dark or Light Bronze.

Print colour varies between Black, White, or Red, Yellow, Blue and Green. We recommend lighter-tone print for darker panels, and vice-versa.

Please note: we don’t stock custom coloured panels. For every custom order we need to make a single panel order from our panel provider. This explains the panel price and lead time.

Thanks for your interest in the ADDAC507!
