Because everyone just hates that
In audio industry, there is about million different versions of things, that has very similar purpose, but are not compatible between each other. Such as plugin APIs (VST, AU, RTAS, ..) or network digital audio protocols (Dante, RedNet, ..).
We minimize the need for custom formats to the absolute necessary minimum. We use widely accepted and well documented standards, such as class-compliant USB. This will never leave Segment players unsupported, just because someone decides he doesn't care anymore. There is literally no vendor lock-in.
Human readable data
We use YAML for storing Segment data. This ensures human readable and well structured files for your sounds, presets and other Segment data. You can edit these files via our preset manager or in standard text editors.
