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

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

55      - fixed application exit on broken pipe error (fixes bug #20)      - fixed application exit on broken pipe error (fixes bug #20)
56        - fixed the notification messages delay due to lack of
57          network activity (fixes bug #26)
58        - fixed parser bug which occured on space(s) within device parameters
59          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")

61      * audio driver:
62        - added aRts audio output driver (by no means RT safe)
