|
- only the API relevant header (and source) files will be exported to |
| 5 |
|
the Doxygen API documentation (explicitly listed in Doxyfile.in) |
| 6 |
|
|
| 7 |
|
* general changes: |
| 8 |
|
- replaced the old, confusing MIDI program change mechanism by a |
| 9 |
|
flexible MIDI instrument mapper which allows to map arbitrary |
| 10 |
|
(MIDI bank, MIDI program) pairs with arbitrary |
| 11 |
|
(engine type, instrument file, file index) triplets which will be |
| 12 |
|
loaded on the respective channel when such MIDI program change |
| 13 |
|
messages arrive, beside that, each entry allows to define a life-time |
| 14 |
|
strategy for the instrument, so the user can define whether the |
| 15 |
|
instrument should i.e. be permanently loaded (to be able to switch |
| 16 |
|
quickly among sounds) or i.e. loaded just on demand when the |
| 17 |
|
respective program change arrives (to safe RAM space), as well as a |
| 18 |
|
global volume factor for each entry, so the user can adjust the volume |
| 19 |
|
dynamic of his mapped instrument collection without having to modify |
| 20 |
|
the instrument files, also one can manage arbitrary amount of such |
| 21 |
|
MIDI instrument maps and assign each sampler channel individually |
| 22 |
|
a certain map, so that i.e. separation of normal instruments and |
| 23 |
|
drumkits is possible |
| 24 |
|
- new notification events for tracking changes to audio/MIDI devices, |
| 25 |
|
MIDI instrument maps, MIDI instruments, FX sends, global volume. |
| 26 |
|
- sampler was limited to load max. 200 instruments in the background |
| 27 |
|
due to a constant size RingBuffer FIFO which is now replaced by a |
| 28 |
|
dynamic (unlimited) size std::list FIFO |
| 29 |
|
- added FX sends, these allow to route audio signals to arbitrary audio |
| 30 |
|
output channels for being processed by external effect processors |
| 31 |
|
(i.e. jack-rack), the send levels are controllable via arbitrary MIDI |
| 32 |
|
controllers |
| 33 |
|
- global (sampler wide) volume can now be controlled at runtime |
| 34 |
|
- Implemented new, improved notification system |
| 35 |
|
|
| 36 |
|
* MIDI driver: |
| 37 |
|
- dispatch bank select (MSB and LSB) messages |
| 38 |
|
|
| 39 |
|
* audio driver: |
| 40 |
|
- the ALSA audio output driver parameters now reflect the correct |
| 41 |
|
parameter value ranges for the respective selected sound card |
| 42 |
|
(patch by Till Wimmer, a bit fixed and extended) |
| 43 |
|
|
| 44 |
|
* Gigasampler format engine: |
| 45 |
|
- if a filter is used and EG2 finishes before EG1, let the voice |
| 46 |
|
die when EG2 has finished (this fixes a problem with clicks and |
| 47 |
|
voice starvation for some gigs) |
| 48 |
|
- playback is no longer disabled during instrument loading |
| 49 |
|
- all notes playing on a channel that changes its instrument keep |
| 50 |
|
playing with the old instrument until they get a note off |
| 51 |
|
command |
| 52 |
|
- EG fix: a release value of zero could cause noises or crash |
| 53 |
|
- handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB) |
| 54 |
|
- EG fine tuning: when attack is zero the EG starts at a level |
| 55 |
|
above max sustain level, which means that there is a decay phase |
| 56 |
|
even if sustain is 100% |
| 57 |
|
- more EG fixes: the level could sometimes go below zero and cause |
| 58 |
|
noises or crashes |
| 59 |
|
|
| 60 |
|
* Bug fixes: |
| 61 |
|
- fixed crash occurring on certain LSCP scripts (Bug 39) |
| 62 |
|
- another thread safety fix for lscp "load engine" and "set |
| 63 |
|
channel audio output device" |
| 64 |

|
- added global volume attenuation of -9 dB (0.35f) to prevent clipping |
| 106 |
|
which can be overridden with --enable-global-attenuation |
| 107 |
|
- EG fixes: made the length of "attack hold" stage more |
| 108 |
|
accurate. Release stage can now start before attack stage |
| 109 |
|
ends. Cancel release didn't work when sustain was zero. Attack |
| 110 |
|
time now has a minimal value to prevent clicks. |
| 111 |
|
- fixed pitch changes larger than one octave |
| 112 |
|
- fixed EG3 (pitch envelope) synthesis which was neutral all the time |
| 113 |
|
- implemented portamento mode and solo mode (a.k.a 'mono mode'): |
| 114 |
|
all modes can be altered via standard GM messages, that is CC5 for |
| 115 |
|
altering portamento time, CC65 for enabling / disabling portamento |
| 116 |
|
mode, CC126 for enabling solo mode and CC127 for disabling solo mode |
| 117 |
|
- fine tuning of the curves for volume (CC7), pan (CC10 and gig |
| 118 |
|
parameter) and crossfade |
| 119 |
|
- added support for the "attenuation controller threshold" gig |

|

| 121 |

- added smoothing of volume changes caused by control change |

|
messages |
| 123 |
|
- sample loop parameters are now taken from the DimensionRegion |
| 124 |
|
instead of the wave chunk |
| 125 |
|
- fixed keyswitching for v3 gigs with a number of keyswitch splits |
| 126 |
|
not equal to a power of two |
| 127 |
|
- reimplementation of the filter algorithm. The new filter is more |
| 128 |
|
accurate and supports all gig filter types, including bandreject |
| 129 |
|
and lowpass turbo. |
| 130 |
|
- real support for 24 bit samples - samples are not truncated to |
| 131 |
|
16 bits anymore |
| 132 |
|
- support for aftertouch (channel pressure, not polyphonic |
| 133 |
|
aftertouch) |
| 134 |
|
- LFO1 behaviour fixed (dampening from max volume instead of |
| 135 |
|
amplifying from 0) |
