A DLL (Dynamic Link Library) to program MIDI Files of types SMF0 or SMF1. The DLL can be called from C++ applications and offers interfaces for Visual Basic, VB Net and C#.

The freeware MIDI File DLL "HP MIDIFILE" includes functions to load MIDI Files or create new ones, to read, insert, delete, change all MIDI Events of GM1/GM2 and of YAMAHA XG/XF. With functions Select, Copy and Paste sets of events can be inserted at other timepoints into the same or another MIDI File. There are functions to find and select MIDI Devices and to play the loaded song.

HP MIDIFILE is intended to simplify the creation and editing of MIDI Files. Most of the functions work with the logic of events, not with internal data.

HP MIDIFILE also offers functions to read items of Cakewalk/Sonar Instrument Definition Files.

The user of this library must be familiar with the structure of MIDI and MIDI Files. Applying YAMAHA SysEx and Meta Events he should look at XG and XF specifications. A lot of good documents can be found in the internet.

HP MIDIFILE is mainly implemented for the programming language Visual C++ for Windows of all versions: Win98, Win2000 and XP.

Based on HP MIDIFILE I have programmed the freeware application PSRUTI. Look at Downloads in hpmusic
