* Added support for most of the extended capabilities of the CM-32L/LAPC-I (more rhythm timbres, more rhythm key mappings, more PCM samples). * The control ROM is now identified by searching for matching ID strings at various locations in the file. There are now a lot of safety checks to help ensure that a bad ROM will not crash the emulator. * Three control ROM versions are now identified and mapped out - an original MT-32 control ROM, an original CM-32L ROM, and the Blue Ridge modified MT-32 ROM. * Now supports the expression controller properly. * Sustain is now turned off correctly again. * "All Notes Off" no longer stops notes held by the sustain controller. * Implemented "Reset all controllers". * Stereo pan positions are no longer inverted. * Volume, pitch, filter and envelopes are now more accurately calculated. Overall, the sound emulation is much more accurate. * Waveforms are now slightly more accurate (in terms of pitch), necessitating a regeneration. * Handling of unusual sysex messages has been improved (fixes sysex messages from Java's MIDI classes on Windows). * Fixed a reverb bug during periods of silence. svn-id: r17188
