The Holonic Source module for VCV Rack integrates with the Holon.ist iOS app and outputs control signals to VCV Rack.
The receiving bus selector determines from which bus the module receives signals. This allows use of multiple instances of the module in a patch, providing up to 64 channels of control.
Activity LEDs for each channel indicate when Holonic Source receives OSC messages for the particular channel and receiving bus.
For the scaling of values.
Low Pass Filters
An adjustable slew is included to smooth signals as desired.
VCV rack expects values between 0v and +10v for unipolar and between -5v and +5v for bipolar signals.
Holonic Source clips signals to -10v, +10v.
Ensure that values are properly scaled in the Holon.ist scaling section.
OSC Message Format
Dumbwaiter is an addressable 8 step sequencer and switch. One could see it as the lower row of the Doepfer A-155 with a large helping of A-154 functionality.
Lazy Susan is a quad quantiser with user editable scales. For your convenience, your custom scales are saved with each patch. By default, the scales are the 7 standard modes: Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian
Serving suggestion: The Doepfer A-156 Quantiser minor mode is a melodic minor scale (CmMaj7). Choose the Dorian scale and sharpen the 7th to harmonize with your Eurorack.
Pantry is a Dual CV/Gate Recorder/Looper.

Gaps is a clock divider that supports multiple modes.
- Integers: 2,3,4,5,6,7,8,9
- Even : 2,4,6,8,10,12,14,16
- Odd: 3,5,7,9,11,13,15,17
- Prime: 2,3,5,7,11,13,17,19
- Binary: 2,4,8,16,32,64,128,256
- Random: random probabilities 1/2, 1/3, 1/4, 1/5, 1/6, 1/7, 1/8, 1/9
- 8 step clock Sequencer
Four modes are available:
- Gate: the output stays high until the next clock input trigger
- Gate2: the output stays high half of the time (50% duty cycle)
- Trig: the output outputs the standard trigger upon input trigger
- As is: the output remains high as long as the clock input is high
Additionally, Gaps can behave in two ways:
- Musical: triggers on the first clock
- Mathematical: if the divide ratio is say 3, it will trigger on the 3rd clock
A simple dual switch with two inputs and one output.
Two modes are available:
- Gate: the input A is used when input is low, input B is used otherwise
- Trig: upon trigger input the module flip flop between input A and B
We’ve created a number of patches and templates that can be used as starting points, or just enjoyed, at: https://patchstorage.com/author/holmium/
You can use any of the included Holonist factory presets to control the patches.
Also, we’ve put together some VCV demo patches using the Holonic Source. They use the default mappings in the Holon.ist app.
Our demos are packaged with the plugins, they are located in:
Alternatively, you can download them directly from here :
The demo patches require the following VCV Rack plugins to be installed:
- Amalgamated Harmonics
- Audible Instruments
- Holonic Systems – Free
- JW Modules
- ML Modules
- Stellare Link
- Vult Modules – Free
Please check the following installation steps below to avoid common pitfalls, such as firewalls, and to ensure full functionality of the autodetection feature.
