suggestion for the Makefile.am to fix the problems with automake
1.6
2002-07-13 Tim Goetze <tim@quitte.de>
* src/iiwu_synth.c (iiwu_synth_alloc_voice): New algorithm for
voice allocation, when all voice processes are in use
2002-07-13 Markus Nentwig <nentwig@users.sourceforge.net>

2002-07-08 Markus Nentwig <nentwig@users.sourceforge.net>
* src/iiwu_synth.c (iiwu_synth_noteoff): Changed noteoff strategy:

2002-07-13 Peter Hanappe <peter@hanappe.com>
* src/Makefile.am (EXTRA_libiiwusynth_la_SOURCES): Applied Takashi
Iwai's patch. The configure stuff in iiwusynth-0.2 cannot be

* src/iiwusynth.c (main): Changed default gain to 0.2.

(iiwu_voice_init): sample position, IIR filter history, envelopes etc. are reset.
(iiwu_voice_optimize): The generators (nominal value) have been set by the sound font.
Now each modulator is calculated once to obtain the 'final' initial value for each
generator, which consists of nominal value and modulator-contributed part.
(iiwu_voice_update_param): Calculates all voice parameters, which depend on one
particular generator. This is called once for each voice parameter during
voice_optimize and further each time, when a modulator changes a generator.
(iiwu_voice_update_param): Added a voice parameter filter_gain to avoid
recalculating the filter gain each time the center frequency changes (it depends
only on Q)
(iiwu_voice_write): Voice is now turned off, when the amplitude falls below -100 dB,
even during the sustain phase (happens, when holding a piano key for a very long time)
* src/iiwu_voice.c (iiwu_voice_noteoff): Moved voice->chan = NO_CHANNEL into iiwu_voice_off.
Previously a released note was not modulated anymore, for example pitch bend stopped working as soon
as the key was released.
* src/iiwu_voice.h: Changed _ON macro to figure out the state of a key from the position in
the envelope, instead of using a cleared channel number as indicator.

(iiwu_inst_zone_import_sfont): Import of modulators
(iiwu_defpreset_noteon): Added modulators, fixed generator problem (local zone overwrites global zone, previously it added)
* src/iiwu_conv.c: Using now oncave / convex equation from SF specs.
Removed ct2hz functions and tables.
(iiwu_ct2hz): Limit checking
(iiwu_cb2amp): Removed 'magic number'
(iiwu_tc2sec): Avoided == for iiwu_real_t
* src/iiwu_cmd.c: Increased number of tokens. Using WORKLINELENGTH constant.
Changed max. gain to 5.
Added LADSPA commands.
Renamed misleading rev_bypass command to rev_enable
