OwlProgram v21.0

Matches release v21.0 of OpenWare. Adds support for patch resources.

v12

New features:

• extended parameters: up to 24 parameters controlled by MIDI
• incoming events: handle button presses and MIDI note on/off messages in the patch
• outgoing events: send parameter and button changes as MIDI CC and note on/off messages
• parameter defaults, ranges, smoothing, hysteresis, and non-linearity (exponential and logarithmic curves)

v11

Changes:

• new library classes: AdsrEnvelope, VoltsPerOctave
• updates to web audio processing
• sample accurate button states
• full compatibility with OWL v11 firmware
• improvements to FAUST build

v10

OwlProgram release, including OWL Library, to coincide with release v10 of the OWL Firmware.
