  • Added the Sum Mode parameter to the Precision Adder (fractional offsets) algorithm.
  • Added a further mode to the Half-wave Rectifier algorithm offering dual independent rectifiers.
  • Added parameters to the Sample and Hold and Dual Sample and Hold algorithms to add noise into the inputs.
  • Added the ‘-retriggerOnSampleChange’ playlist option for MIDI playback.
  • Fixed a problem where the Audio Playback with Scrub algorithm would stop playback if the playback position went off the end of the sample.
  • Fixed a problem where specifying an empty folder in an audio playlist and then selecting that folder would then cause the folder parameter to revert to zero.
