vsrs

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

Installing

You need to have Rust installed, see https://www.rust-lang.org/tools/install for installation instructions.

cargo install vsrs

Running

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!

Gotchas

• 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.

Practical Examples

Check out the contrib directory for configuration file examples.
