fluidsynth 2.4.0

New Features

• Implement MSGS-style Drum Note Cut (#1199)
• Support KAI audio driver on OS/2 (#1332, thanks to @komh)
• Add support for AWE32 NRPNs (#1346)

Musically Breaking changes

• The default settings for reverb and chorus have been tuned to provide a more natural perception (#1282, thanks to @es20490446e)
• The behavior of the volume envelope's delay phase was previously incorrect (#1312)
• The ModLfoToVolume generator was not able to increase the volume (#1374)
• Fluidsynth's default device-id was changed, allowing it to process (most) SysEX events without further configuration (#1382)
• Previously, some modulators were treated in a non-standard way (#1392, #1389, #1068)

Bug Fixes

• The former linear interpolation of IIR filter coefficients could have caused audible clicks and cracks (#1345) - yet there is still a potential for clicks and cracks, see #1415
