Uploading DLS/SF2 files to Sweet MIDI Player for iOS.
You can upload your own synthesizer sound library
files in a format called DLS or SF2. DLS/SF2 is a family of standardized
file formats for digital musical instrument sound banks (collections
of virtual musical instrument programs).
Various DLS/SF2 files.
Below are som DLS/SF2 files that customers have sent us. Files bigger than maybe 30-40 MBytes might not work on older iPhone/iPad devices with a small amount of RAM (in fact it may crash an app trying to load such a file if the app runs out of memory). Although some of the files have very good sound quality, the volume levels might be quite different compairing to a regular Roland General MIDI DLS file.
Some personal comments.
Many downloaded MIDI files (and even some commercial
files) are programmed very badly by people that are not very good musicians.
To make them sound better many users tries to find "better sounding"
DLS/SF2 files but in general, MIDI files programmed and performed by
"real" musicians sounds very good even (or even better) with
small DLS/SF2 files such as the "FreeFont.sf2" file.
