Thu Oct 3 13:37:25 2019 UTC (4 years, 6 months ago) by schoenebeck
File size: 28781 byte(s) 
* gig format extension: Added support for different LFO wave forms
  (currently either sine [default], triangle, saw or square).

* gig format extension: Added support for LFO phase displacement
  (0°..360°).

* gig format extension: Added support for flipping LFO polarity on LFO 3
  (in the original gig format this was only available for LFO 1 and LFO 2).

* Bumped version (2.1.1.svn22).
