VCV Rack plugin with Patchable Devices modules

Patchable Devices

VCV Rack plugin with Patchable Devices modules

The main goal of this VCV Rack plugin is to introduce the concept of patch programmability - it means that a module, on the surface, serves very basic functionality, but can completely change its behavior when patched (either to itself or other modules).

Although the patch programmability term is heavily associated within Serge system synthesizers, Patchable Devices plugin takes additional inspirations from different manufacturers to extend the experience.

Each module has a dedicated page in the manual with thorough explanation of the module's inputs, outputs, features and patching tips. Please refer to this documentation if you have any troubles using the modules. If you discover a bug in the plugin, don't hesitate to create an issue.

How to install

Method 1: VCV Rack Library

The main installation method is to add the plugin to your account on official VCV Rack library. The plugin will be available for download after successful VCV Rack launch and login.

Method 2: Building from source

You can follow these steps to build this plugin locally.

Digital Chaotic System crashes Rack 2.4.1 on Mac arm64 on add

Nonlinear Integrator - Output levels vs Resonance

Hi,

I checked out your Patchable Devices modules in VCV Rack. Great stuff.

For the Nonlinear Integrator: when adding Resonance, the overall output level increases quite a bit.

Suggestion: Add some form of Output Level reduction when adding Resonance.

Window Generators - Time values set/displayed for envelope/function segments are not the actual times

Hi,

I checked out your Patchable Devices modules in VCV Rack. Great stuff.

Time values set/displayed for envelope/function segments are not the actual times. Also, they seem to be relative to adjectent levels.

Suggest to find an algortithm that respects the actual time as set, also independent of values for other knobs.

Dual Integrator - As a VCA it does not go to 0 (silence) via CV

Hi,

I tried out your Patchable Devices modules in VCV Rack. Great stuff!

I tried to use the Dual integrator as a VCA (and/or filter/Low Pass Gate). It seems that it will not completely go down to 0 V / silence via CV?

Window Generators - Reverse direction of knobs for time parameters

Hi,

I checked out your Patchable Devices modules in VCV Rack. Great stuff.

The direction of Windows Generators knobs are unintuitive to me. Cuurently: longer times to the right and shorter times to the left.

My GUI intuition tells me: shorter times to the left and longer times to the right.

Window Generators - Behaviour when Sustain at 0 (zero)

Hi,

I tried out your Patchable Devices modules in VCV Rack. Great stuff!

Not sure about the behaviour of Window Generators when Sustain is at 0 (zero). It seems to mess up the staging? I noticed that gating/triggering would no longer give me an envelope/funtion when sustain is set to 0? Maybe this is related to the relative nature of the stages times/levels?

I was actually trying to set up AD and AR envelopes. Maybe I just don't get it (yet). Maybe I was using the wrong segments config (AHDSR with no H and no S or R). Maybe Window Generators can handle this fine with some explanation/instruction.

Voltage Sequencer - Stage selected vs All gates

Hi,

I checked out your Patchable Devices modules in VCV Rack. Great stuff.

Voltage sequencer has an output labeled Stage selected, but also All gates. I expected it to give me all gates for active steps.

Suggestion: Add an option to (also) output a gate for each step with a Voltage other the zero (0 Volt). So the All gates output could be used to provide a per step gate. Also: add gate length? So for steps with a gate length smaller then 100% we would get 2 gates instead of a continous gate. If small enough, you would in effect get a Trigger.
