Command line utility for generating sample streams for the Volca Sample
Using a configuration file you configure which samples to use, which indexes to put them in, and whether samples should be compressed. You can also generate a stream with the factory preset samples by using a .alldata file.
The tool outputs a .wav
file which is ready to
be used for transferring the data to the Volca Sample. For details on the transfer process refer to
transferring syrostream to your volca sample
You need to have Rust installed, see https://www.rust-lang.org/tools/install for installation instructions.
cargo install vsrs
Loading a configuration file
vsrs load example.ron
Restoring factory settings using a .alldata file. Files can be found at https://github.com/korginc/volcasample/tree/master/alldata
vsrs reset all_sample_preset.alldata
To play the .wav
file from the command line you can use aplay
on Linux, or afplay
on macOs.
WARNING: do not play over speakers, make sure you've set up audio correctly to play into the volca first!
- It's good practice to wipe the sample memory with
all_sample_empty.alldata
before loading new samples, otherwise there's a higher risk of getting a memory full error.
Check out the contrib directory for configuration file examples.
