 * OPN2 emulation
 * Stereo sound
-* Number of simulated soundcards can be specified as 1-100 (maximum channels 1800!)
+* Number of simulated chips can be specified as 1-100 (maximum channels 600!)
 * Pan (binary panning, i.e. left/right side on/off)
 * Pitch-bender with adjustable range
 * Vibrato that responds to RPN/NRPN parameters

 * Use automatic arpeggio with chords to relieve channel pressure
 * Support for multiple concurrent MIDI synthesizers (per-track device/port select FF 09 message), can be used to overcome 16 channel limit
 
+# How to build
+You can build shared version and additional tools on the Linux when you will run a "make" command and you will have libopnmidi.so in the "bin" directory.
+
+You also can build library manually:
+You need to make in the any IDE a library project and put into it next files
+(or include those files into subfolder of your exist project instead if you want to use it statically):
+
+* opnmidi.h    - Library API, use it to control library
+
+* Ym2612_Emu.h  - Yamaha OPN2 Emulation header
+* fraction.h    - Fraction number handling
+* opnbank.h    - bank structures definition
+* opnmidi_private.hpp - header of internal private APIs
+* opnmidi_mus2mid.h - MUS2MID converter header
+* opnmidi_xmi2mid.h - XMI2MID converter header
+
+* Ym2612_Emu.cpp   - code of Yamaha OPN2 emulator by Stéphane Dallongeville, improved by Shay Green
+* opnmidi.cpp   - code of library
+
+* opnmidi_load.cpp	- Source of file loading and parsing processing
+* opnmidi_midiplay.cpp	- MIDI event sequencer
+* opnmidi_opn2.cpp	- OPN2 chips manager
+* opnmidi_private.cpp	- some internal functions sources
+* opnmidi_mus2mid.c	- MUS2MID converter source
+* opnmidi_xmi2mid.c	- XMI2MID converter source
