Mon Sep 26 10:17:00 2005 UTC (13 years, 10 months ago) by schoenebeck
Original Path: linuxsampler/trunk/configure.in
File size: 34983 byte(s)
* fixed event handling bug which was introduced by the recent synthesis
  optimizations (events were only processed for the first active voice)
* added global volume attenuation of -9 dB (0.35f) to prevent clipping
  which can be overridden with --enable-global-attenuation

11 # The following is the libtool / shared library version. This doesn't have to
12 # do anything with the release version. It MUST conform to the following rules:
13 #
14 # 1. Start with version information of `0:0:0' for each libtool library.
15 # 2. Update the version information only immediately before a public release of
16 # your software. More frequent updates are unnecessary, and only guarantee
17 # that the current interface number gets larger faster.
18 # 3. If the library source code has changed at all since the last update, then
19 # increment revision (`c:r:a' becomes `c:r+1:a').
20 # 4. If any interfaces have been added, removed, or changed since the last update,
21 # increment current, and set revision to 0.
22 # 5. If any interfaces have been added since the last public release, then increment
23 # age.
24 # 6. If any interfaces have been removed since the last public release, then set age
25 # to 0.
