17        - added compile time options to allow disabling the various audio and
18          MIDI drivers

30        following gig parameters: Cutoff freq (used when no cutoff        following gig parameters: Cutoff freq (used when no cutoff

33        cutoff frequency, not just resonance.        cutoff frequency instead of resonance.
34        - filter fine tuning: calculation of cutoff frequency and
35          bandwidth improved. Removed use of "BasicBPFilter". Changed
36          bandpass filter from constant peak to constant skirt. Added
37          support for gig parameter Resonance.
38      - fixed bug in sysex handling (patch by Juan Linietsky)      - fixed bug in sysex handling (patch by Juan Linietsky)
39        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
40          which can be overridden with --enable-global-attenuation
41        - EG fixes: made the length of "attack hold" stage more
42          accurate. Release stage can now start before attack stage
43          ends. Cancel release didn't work when sustain was zero. Attack
44          time now has a minimal value to prevent clicks.
45        - fixed pitch changes larger than one octave
46        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
47        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
48          all modes can be altered via standard GM messages, that is CC5 for
49          altering portamento time, CC65 for enabling / disabling portamento
50          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
51        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
52          parameter) and crossfade
53        - added support for the "attenuation controller threshold" gig
54          parameter
55        - added smoothing of volume changes caused by control change
56          messages
57        - sample loop parameters are now taken from the DimensionRegion
58          instead of the wave chunk
59        - fixed keyswitching for v3 gigs with a number of keyswitch splits
60          not equal to a power of two

63      - fixed application exit on broken pipe error (fixes bug #20)      - fixed application exit on broken pipe error (fixes bug #20)
64        - fixed the notification messages delay due to lack of
65          network activity (fixes bug #26)
66        - fixed parser bug which occured on space(s) within device parameters
67          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
68    
69      * audio driver:
70        - added aRts audio output driver (by no means RT safe)

88        - fixed some memory management errors
89        - fixed some concurrency problems that could lead to crashes when
