Projects and files¶
Various types of files are used to store and recall the state of the many systems inside the PolyPulse. Complete projects can also be stored or recalled.
The file browser¶
The file browser allows you to browse the internal file system of the PolyPulse to load and save files or projects.
Press files to open/close the file browser.
Use X to scroll through the files.
Press yes to load a file or open a folder.
Press no to exit folder, go to parent folder.
Tip
Multiple audio files can be loaded simultaneously. Press shift to (de)select a file or hold shift while scrolling to quickly (de)select multiple files. Then press yes to load all selected files.
Warning
Loading instrument files, large audio files or projects while the instrument is playing will likely result in unwanted clicks and artifacts.
Saving a new file¶
Press files to open the file browser.
Find the location where you want to store your file.
Press edit and select save new file.
Select the file type you want to save.
Enter the name of the new file and press yes twice to save the file.
Overwriting a file¶
Press files to open the file browser.
Find the file that you want to overwrite. When saving a project, overwrite the .proj file.
Press edit and select overwrite.
Press yes to overwrite the file.

Projects¶
Projects are organized into dedicated project folders. Inside the project you will find a .proj file and several other included files. By loading the .proj file all the other files included in the project will also be loaded. The individual files inside a project can be manually loaded or overwritten.
Tip
Loading a complete project will interrupt the sound. To transition between two projects during a live performance, you can load individual files of the next song on an unused track. With that you can introduce musical elements of the next song while keeping some sounds of the current song going.
A template project can be created that is automatically loaded when the PolyPulse firmware start. Simply create a project called template inside the projects folder.
Audio files¶
The PolyPulse can load a variety of audio file formats and does not require audio files to be converted to specific bit-depths or sample rates. File formats that can be loaded include:
WAV
AIFF
Ogg/Vorbis
FLAC
Files recorded using the PolyPulses internal recorder are stored as 16-bit 48 kHz .wav files.
Note
A full list of supported audio file formats can be found here. Note that the PolyPulse currently uses libsoundfile version 1.0.27-3 and thus cannot read Ogg/Opus or MP3 files.
