MIDI (Musical Instrument Digital Interface) is a protocol and file format that stores musical performance data rather than actual audio waveforms.
DSDIFF, Direct Stream Digital audio for SACD and high-res audio — stored as audio/x-dff — uses lossless encoding to handle audiophile music, high-resolution audio archiving. Typical file sizes: varies by content.
Reach for MID when your priority is music production, electronic instruments — its efficient compression makes sharing fast and storage minimal.

No, converting MID to DFF does not cause additional quality loss — DFF uses lossless compression. However, any artifacts already present in the original MID file will persist in the DFF output.
DFF files are typically 2-5x larger than equivalent MID files because DFF preserves all pixel data. This is expected and necessary for lossless quality.
