There are 2 different circuits in this module: voices 1 to 3 have a pre-vca t-network filter while in voice 4 the t-networks filter applied post-vca.
At each voice input there’s a switch that sets which type of input to use; this signal will be used to control an internal VCA hence why the type of setting defined here is important:
1. Trigger - Any incoming CV will be converted into a 1ms trigger as soon as it crosses its fixed threshold.
2. Mute - This disconnects then incoming signal effectivelly muting the voice.
3. Envelopes - This can be used with CV sources as well as Gate sources and simply follows the input signal.
This incoming signal will then be processed by a slew circuit which adds a decay factor allowing the user to set the “Tail” of each voice.
Trigger mode is mostly dedicated for percussive sounds while the Envelope mode is open to any external envelope control and able to control noise swooshes, swirls, crackles and pops simply out of t-networks filtered noise.
Audio inputs also welcome use as a Trigger/Envelope input, in fact the results of using this method had us all extremely surprised, so please do try it out!
Diferences between voices:
The first 3 voices also feature a Timbre selector switch: Hat/Snare
In Snare mode all frequencies coming from the t-networks filter pass through to the output .
In Hat mode it adds a High Pass circuit which removes the mid/bottom frequencies (characteristic of the snare strike) creating a higher spectrum output which is closer to a Hat timbre.
All of these 3 voices are also differently tuned from each other to offer more timbrical options.
Voice 4 is closer to a typical t-networks circuit but this time a peculiar one where the noise is gated by the vca and then sent through the t-networks filter.
Hat and Snare are terms used very loosely here; they are timbrical references and do not in any shape or form try to effectively replicate the complex timbres of a real world Hat or Snare.
4 Voices each with:
• Frequency control
• Decay control
• Timbre type, Hat/Snare (Voice 1 to 3)
• Frequency Range Switch, Low/Mod/High (Voice 4) Input
• Audio Output
• Also and overall Summing Mix output with Volume control and 2 diferent output types (Normal/Dirt)

ADDAC develops advanced instruments for sonic expression.
We started back in 2009 with an ambition to explore the potential crossover between analog synthesizers and computers. Because our first creations sparked a lot of attention, we decided to work hard and put them in your hands.
Today our product line is focused on a new breed of hybrid synths, that make use of the best of both the digital and analog worlds. We've grown to be able to reach thousands of enthusiastic clients, friends and collaborators. Always looking into conceptualizing and developing the most exquisite instruments, we hope you're able to join and share this passion with us.
Our solutions can be found in many personal studio throught the world, owned by musicians in several planes of stardom. We especially appreciate seeing them being used in a very wide range of musical genres.
