3      * general changes:
4        - replaced the old, confusing MIDI program change mechanism by a
5          flexible MIDI instrument mapper which allows to map arbitrary
6          (MIDI bank MSB, MIDI bank LSB, MIDI program) triplets with arbitrary
7          (engine type, instrument file, file index) triplets which will be
8          loaded on the respective channel when such MIDI program change
9          messages arrive, beside that, each entry allows to define a life-time
10          strategy for the instrument, so the user can define whether the
11          instrument should i.e. be permanently loaded (to be able to switch
12          quickly among sounds) or i.e. loaded just on demand when the
13          respective program change arrives (to safe RAM space), as well as a
14          global volume factor for each entry, so the user can adjust the volume
15          dynamic of his mapped instrument collection without having to modify
16          the instrument files
17    
18      * MIDI driver:
19        - dispatch bank select (MSB and LSB) messages
20    
21      * Gigasampler format engine:
22        - if a filter is used and EG2 finishes before EG1, let the voice
23          die when EG2 has finished (this fixes a problem with clicks and
24          voice starvation for some gigs)
