Initial revision
2003-03-11 16:56:45 +00:00
2003-02-27 Josh Green <jgreen@users.sourceforge.net>
Updated automake files (automake 1.6).
* configure.ac: New version autoconf variables which get substituted
into include/iiwusynth/version.h.in.
* include/iiwusynth/version.h.in: Version defines that are filled in
by autoconf.
* src/Makefile.am: Fixed SOURCES including removing headers that are
now in include/iiwusynth/, added missing sources (iiwu_ramsfont.[ch],
iiwu_sfont.h) and added iiwu_dsp_core.c to EXTRA_DIST.
* doc/Makefile.am: Added iiwusynth.1 to EXTRA_DIST.
* include/iiwusynth.h: Added version.h.
* iiwusynth/Makefile.am: Added version.h to the installed headers.
2003-02-08 Markus Nentwig <nentwig@users.sourceforge.net>
* src/iiwu_ladspa.c: Added a very small signal at Nyquist
frequency. This fixes denormal number problems in some
plugins.
* src/iiwu_cmd.c (iiwu_shell_run): Now also invalid input lines
are added to the command line history. So the user can just scroll
up and fix them.
* src/iiwu_ladspa.c: Cleaned up error messages
* src/iiwu_dsp_core.c: Disabled SSE interpolation, because it is
slower than the normal code
* autogen.sh: Added a line, that checks for the presence of pkg-config in
autogen.sh.
Motivation: It took me some time to figure out what was wrong...
It produces some error message instead of an obscure error later
during ./configure, if pkg-config is not installed.
2003-02-07 Josh Green <jgreen@users.sourceforge.net>
Applied another Bob Ham LADCCA patch.
* src/iiwu_alsa.c: LADCCA patch: Now using a ladcca.enable setting.
* src/iiwu_jack.c: LADCCA patch: ladcca.enable setting and jack ports
are no longer auto connected unless audio.jack.autoconnect is set.
* src/iiwusynth.c: LADCCA patch: ladcca.enable and command line options
-j and --connect-jack-outputs to enable Jack autoconnect.
2003-02-05 Josh Green <jgreen@users.sourceforge.net>
Applied Bob Ham's LADCCA and pkgconfig patches.
* Makefile.am: pkgconfig patch.
* configure.ac: Renamed from configure.in as per new autoconf
standards. LADCCA configure switch and detection. FluidSynth.pc
pkgconfig file output.
* src/Makefile.am: LADCCA patch.
* src/iiwu_alsa.c [HAVE_LADCCA]: LADCCA patch: reports ALSA
sequencer client ID.
* src/iiwu_jack.c [HAVE_LADCCA]: LADCCA patch: reports JACK
client name.
* src/iiwusynth.c [HAVE_LADCCA]: LADCCA patch: connects to LADCCA
server, creates client thread, saves/restores SoundFont file state.
Used iiwu_sfont_get_name macro to get SoundFont file names contrary
to the patch. Should these macros be public? Included unistd.h
for usleep call (within HAVE_LADCCA).
2003-01-23 Josh Green <jgreen@users.sourceforge.net>
* src/iiwu_jack.c: Fixed a segfault bug caused by freeing jack
port names, when really only the port array should be freed,
jack reference docs are confusing on this matter!
* src/iiwu_voice.c (iiwu_voice_check_sample_sanity): Min loop size
and padding now set via constants IIWU_MIN_LOOP_SIZE and
IIWU_MIN_LOOP_PAD defined at top of iiwu_voice.c, and the values
were lowered to exceed SF spec requirements rather then just meet.
(iiwu_voice_write): Now using a constant IIWU_MAX_AUDIBLE_FILTER_FC
defined at the top of iiwu_voice.c to control the filter
cutoff optimization. Also added IIWU_MIN_AUDIBLE_FILTER_Q so
filter will only turn off if both cutoff and q are determined to be
inaudible. Filter optimization is much less noticeable when modulating.
2003-01-14 Markus Nentwig <nentwig@users.sourceforge.net>
* src/iiwu_ladspa.c: Adapted new command handler
* src/iiwu_midi_router.c (midi_dump_prerouter): Added forgotten
'flush' for event dump 'fprintf's

* src/iiwu_ladspa.c: Adapted to new settings system
* src/iiwu_adriver.c (iiwu_audio_driver_settings): Uses getint
instead of getnum for audio.period-size and audio.periods settings.

Ignore the valid flag for samples. Otherwise no sound is produced.
* src/iiwu_chan.c (iiwu_channel_cc): Fixed bank select (7-bit
instead of 8 bit)
2002-12-23 Peter Hanappe <peter@hanappe.com>

system).
* src/iiwu_voice.c (iiwu_voice_update_param): Does more extensive
range checking because the NPRN system may produce out-of-range

* src/iiwu_dsound.c (iiwu_win32_destroy_window): Filled in the
empty lines...
* src/iiwusynth.h: Changes in the definition for iiwu_synth_sfload
and iiwu_synth_sfunload, New functions: iiwu_synth_sfreload,
iiwu_synth_get_sfont_by_id, and iiwu_list_insert_at. New 'id'
field in iiwu_font_t.

* src/iiwu_settings.c (iiwu_settings_init): Removed
multi_channel from the settings (replaced with audio_channels > 1)
* src/iiwu_settings.c (iiwu_settings_init): added audio_groups
setting. This is the number of individual channels generated from
the synth, and always equal to audio_channels, as long as the
LADSPA Fx unit is disabled. Otherwise it can be used (for
example) to separate even and odd MIDI channels, apply different Fx
and mix together to one stereo output.
src/iiwu_ladspa.c: Extended Fx unit to multigroup input, fx sends
and multiple audio output channels
2002-12-04 Peter Hanappe <peter@hanappe.com>

timer is finished.
* src/iiwu_synth.c (iiwu_synth_sfunload): If the soundfont can not
be unloaded immediately, a timer thread is spinned of to unload it
later. On MacOS 9, the unload is tried at a subsequent 'load' or
'unload' request.

a variable number of midi-channels. The 'flags' has been
expanded/replaced with several variables.
* src/iiwu_chan.c (iiwu_channel_cc): Implemented the 'All Control
Off' MIDI message (CC 121).
* src/iiwu_chorus.c (iiwu_chorus_update): iiwu_chorus_update
(called after the iiwu_chorus_set_xxx function) no longer returns
an error of out-of-range values. It clips the value the the
[min-max] range.
2002-11-22 Markus Nentwig <nentwig@users.sourceforge.net>
* src/iiwu_voice.c (iiwu_voice_write): Fixed compilation problem

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
rebuilt with the latest automake 1.6. You cannot use substitution
for *_SOURCES in Makefile.am. This fixes this problem.

Previously, turning a volume pedal briefly to 0 would quit all voices playing.
* src/iiwu_rev.c (iiwu_revmodel_processreplace): Removed 'dry' path from reverb unit
Motivation: This saves a couple of multiplications, the dry signal goes through the ordinary output
anyway.

to 64.
* src/iiwu_synth.c (iiwu_synth_get_internal_bufsize): added
* src/iiwu_ladspa.h: lower-cased ladspa files
* src/iiwusynth.h: prefixed log levels with IIWU_... Updated all
references.
* src/iiwu_cmd.c (iiwu_handle_reverb): renamed 'rev_enable' to
'reverb' in correspondance with the long command line arguments
* src/iiwusynth.c (main): checking if files on command line are valid
* src/iiwuplay.c (main): checking if files on command line are valid
* src/iiwusynth.h: New log level for verbose messages: IIWU_INFO
2002-04-30 Markus Nentwig <nentwig@users.sourceforge.net>
* src: Added iiwu_LADSPA.c, iiwu_LADSPA.h (support for LADSPA effect plugins).
* src/iiwusynth.c (main): Changed default gain to 0.2.
* src/iiwu_voice.c: Restructured the voice initialization as follows:
(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.
* src/iiwu_synth.c: Implemented all default modulators
Added LADSPA support.
Added digital clipping.
Moved master gain factor ahead of LADSPA Fx.
* src/iiwu_mod.c: 'Hardcoded' GM default modulator vel => filter.
Replaced 128 with 127 in (127-x)
* src/iiwu_midi.c: Fixed sysex for realtime MIDI. Fixed pitch bend bug.
