Designed to be a highly customisable connection matrix, 3DVCA packs a boat load of utility into a small 6HP package. Four VCAs share the three macro controls: X, Y, and Z. As a group, they shape incoming or outgoing signals and emulate the coordinates of a point in 3 dimensional space. -
Page 6: Installation
Ensure the following conditions are correct for trouble free installation. • Rack power supply can accommodate all of the installed modules total current ratings. 3DVCA power requirements are +12V 45mA, -12V 45mA, +5V Not Used. • 3DVCA is 30mm deep. - Page 7 Eurorack Installation. Power cable should only be connected by 3DVCA with the red stripe aligned to the red tag -12V on the power supply. Connect power to the IDC Connector Power Power Back 3DVCA 3DVCA Official Manual...

Envelope CV Mystic Circuits 3DVCA - Quad Vector VCA. Mystic Circuits 3DVCA is a quad VCA in a small 6HP form factor that can operate in mono, stereo or quad configurations. Unlike a traditional quad VCA which allows independent control over each VCA, 3DVCA uses 3 dimensional macro parameters to control all 4 VCA channels together as a group. -
Page 11: Dimensions Of Control
Instead of having control over each VCA individually, 3DVCA uses three Macro controls to control all four VCAs as a group. This paradigm not only allows 3DVCA to be compact, but also performs a variety of functions that benefit from using the VCAs in tandem. Input and output normalization make it easy to send one signal to multiple inputs or mix multiple VCA outputs together in versatile ways. -

NE input jack, it will break the normalization connection and then the arrow and NW input signal is ignored at the NE VCA input. This is where the true power of 3DVCA resides: these normalization connections allow you to use 3DVCA in a multitude of different functions without needing to use a large number of external mults or mixers. -
Page 16: Summing
SUMMING The final feature to explore on 3DVCA is the group of “SUM” inputs located on the left of the panel. Each of these inputs mixes automatically into its dedicated VCA output with the direction of the VCA labeled as a white square pointing away from the jack that it identifies. -
Page 17: Patching Examples With 3Dvca
As you become more familiar with 3DVCA, you might find that you want to use a mono source in a stereo patch, use stereo patching techniques to treat mono sources in parallel, or use one section of 3DVCA for audio and another for control voltages. -
Page 18: Mono Patching With 3Dvca
MONO PATCHING WITH 3DVCA Patch Example 1: Crossfading between 4 Inputs A good place to start with 3DVCA is mixing four signals together in mono. We start by taking four audio signals from your favorite audio sources, plugging them into the four VCA inputs, and then taking our output from the SE output. - Page 19 It’s better to use the “SUM” inputs for signals that have their own envelope, VCA, or volume control built in and to use signals that need their volume shaped into the VCA inputs to take full advantage of each section of 3DVCA. Outputs - Lower Section...
- Page 20 A similar patch involves sending one signal to all four of 3DVCAs outputs. Start by plugging your favorite signal generator into the NW input on 3DVCA and then plug all four outputs of the output square into different destinations: either different effects, modulation inputs, or wherever you might want to send a signal.
- Page 21 In all of these cases you will only be using one half of 3DVCA’s inputs and outputs (two inputs and one output) which leaves the other half to be used as a second parallel crossfader.

STEREO PATCHING WITH 3DVCA Patch Example 5: Standard 2 Input Stereo Channel Using 3DVCA in a stereo context is where this module really shines. When using the standard stereo patch shown below, you are able to crossfade two stereo inputs, set the balance between left and right channels, and control the overall level of the results all with voltage control. - Page 23 Patch Example 6: Mono to Stereo Crossfader & Panner 3DVCA makes it easy to use mono signals in a stereo context. Any time you want to distribute a mono signal into two of the VCAs on 3DVCA you can simply patch your mono signal into the western input on a row and that signal will automatically be distributed across to the eastern input for that row.
- Page 24 If you have another stereo mixer or another 3DVCA, you can now plug the stereo outputs of your other module into the “SUM” inputs of your main 3DVCA with the left channel going into the SW SUM input and the right channel going into the SE SUM input. Now the output of your other mixer module will be automatically mixed into the overall mix coming out of the two outputs of 3DVCA with its stereo image intact.

QUAD PATCHING WITH 3DVCA Patch Example 9: Quad Panner For an important minority of users, the most exciting part of 3DVCA will be working with it in quad. For those that don’t know, quad refers to making music with four unique channels instead of the standard two channels used in stereo. - Page 27 Patch Example 10: Quad Balancer If your audio is already mixed in quad, then you are in luck! 3DVCA can process this audio similarly to the patch mentioned earlier if you plug each channel of your quad signal group into the four VCA inputs and take your quad output from the four VCA outputs. You can then control the balance of the four channels as well as the overall volume using the ‘X’,...
- Page 28 Patch Example 11: Daisy Chaining Quad Mixers A final note on quad usage is that 3DVCA can daisy chain to other 3DVCAs to mix multiple quad audio streams together without needing any other mixer modules. Simply plug the four outputs of 3DVCA into the matching SUM inputs of the next 3DVCA in the chain and your four signals will be mixed all the way down the chain until it finally reaches your output module.

SE output. Plug this into the 1V/Oct input of your favorite VCO (ideally with a quantizer between the 3DVCA output and the oscillator) and now you can switch or mix between the four voltage sequences by activating only one of the four VCAs either with the panel controls or under voltage control. - Page 30 Turning ‘Z’ up will add in the fill sequences, and ‘X’ and ‘Y’ will select which trigger channels are currently being modified. A nice quality of using 3DVCA for triggers is that when used with modules sensitive to trigger levels, having the smooth level control over our trigger sequences will allow you to achieve accents, ghost notes, or multiple levels of volume.
- Page 31 2) to turn off all modulation to avoid the seasick feeling that comes from giving everything its own LFO. 3DVCA is handy in such a scenario because you can take one modulation source and carefully balance where it is sent or mute modulation completely.
