The MIDI event handling in InstrumentTrack was complex and buggy. It has been simplified now such that processInEvent() tries to handle note on, note off and key pressure events. The actions taken should result in equivalent calls to processOutEvent() by NotePlayHandle instances. The processOutEvent() function sends according MIDI events to the attached instruments. All unhandled MIDI events are directly forwarded to the instrument in processInEvent(). It's possible that some corner-cases are not handled yet with the new code and we have regressions now. Furthermore renamed midiTime/midiEvent to MidiTime/MidiEvent to match coding style. Closes #72.
Snatched from AdPlug 2.2.1: adlibemu.c adlibemu.h fmopl.c fmopl.h kemuopl.h opl.h temuopl.cpp temuopl.h mididata.h 1.2.2 Sound generation section ------------------------------ The Sound generation section is responsible for generating the OPL's sound, according to the input of the Playback section. This sound is either routed back to the application for it to do something with it or routed directly to a specific audio hardware. The following headers provide the interface to the sound generation section: `emuopl.h', `temuopl.h', `kemuopl.h', `realopl.h', `silentopl.h', `analopl.h' and `diskopl.h'. All classes inside these headers are derived from the abstract base class `Copl', declared inside the file `opl.h', which provides the common interface for the Backend layer of the Playback section. This interface is not meant for the Frontend layer (i.e. your application). Your application, however, has to call special methods of these classes in order to route the data back, if there is any. `emuopl.h' provides the class `CEmuopl', which implements a virtual OPL emulator, which automatically selects the best available OPL chip emulation and type for each replayer. `temuopl.h' provides the class `CTEmuopl', which is a wrapper class around Tatsuyuki Satoh's fmopl OPL2 emulator, which generates wave audio data to be routed back to the application. `kemuopl.h' provides the class `CKemuopl', which is a wrapper class around Ken Silverman's adlibemu OPL2 emulator, which generates wave audio data to be routed back to the application. `realopl.h' provides the class `CRealopl', which outputs to a real hardware OPL2 or OPL3 chip. No data is routed back to the application. This class is currently only working on x86 hardware. `silentopl.h' provides the class `CSilentopl', which is a dummy OPL2/3, which generates nothing. All data sent to it is forgotten immediately. No data is routed back to the application. `analopl.h' provides the class `CAnalopl', which is the same as `CRealopl', but also provides a 9-channel loudness pseudo-analyzer interface for the application. The loudness data is the only data routed back to the application. `diskopl.h' provides the class `CDiskopl', which is an OPL3 emulator that does not output any sound to the soundcard, but instead writes all received OPL commands to a file in the RdosPlay RAW format.
