Changelog

Sourced from fundsp's changelog.

Changes

Version 0.9

• detector was removed (it did not work).
• New opcode biquad for an arbitrary biquad filter.
• Net32/64 method add was renamed push (it conflicted with the operator implementation).
• Graph syntax was implemented for Net32/64. They can also be combined with components from the preludes.

Version 0.8

• semitone is now semitone_ratio.
• New opcodes feedback2 and fdn2, which include extra feedback loop processing. The extra processing is not applied in the feedforward path.
• Wetness argument was removed from reverb_stereo. Room size argument was added. An average room size is 10 meters. To migrate, replace reverb_stereo(wet, time) with wet * reverb_stereo(10.0, time) & (1.0 - wet) * multipass().
• goertzel is now detector.
• chorus gain was adjusted.
• flanger was tweaked.
• New opcode system with a user provided callback. See the sound module for an example.
• Ability to replace nodes in Net32 and Net64. Improved chaining method.
• Sequencer has been replaced with Sequencer32 and Sequencer64.
