A collection of free ReplicatAudio VCV-Rack modules.
Major work in progress. Many things are incomplete and will change. Do not use these in serious projects that you want to come back to later!
More docs and graphics coming soon.
See Dev docs for development and building info. Specifially the tips doc.

# Clone
git clone https://github.com/ReplicatAudio/ra-rack-modules
# Move to project root
cd ra-rack-modules
# Pull the vcv rack sdk
./util/pull-sdk.sh
# Build and install the plugin (all modules)
./util/make.shThis will automatically install the modules as well (at least for linux).
Contibutions are limited to people I know personally at this time. If you know me and want to make a PR feel free. PRs may be open to the public in the future.
