Major Features

• New, all clojure, in-memory scsynth interface using clj-native
• GUI widgets using seesaw and swing (see examples in overtone.examples.gui)
  • synth controls to adjust parameters (synth-controller, live-synth-controller)
  • mixer for instruments (mixer)
  • piano roll and two types of step sequencers (piano-roll, step-sequencer, stepinator)
  • x,y,z surface controller (surface)
  • wave-form and wave-table editors for wave-table synthesis (waveform-editor, wavetable-editor)
  • basic spectrogram showing frequency space representation (spectrogram)
• New event handler on-latest-event which serially handles incoming events with the lowest latency by dropping events it hasn't had time to handle, yet always handling the last event seen.
• Major progress has been made porting the metadata for the extra ugens not included by default in SuperCollider. See overtone/sc/machinery/ugen/metadata/extras/README.md for progress
• Complete overhaul of the default group structure. See foundation-* fns below.

New fns

• on-latest-event - Handles events with minimum latency - drops events it can't handle in time
• event-monitor-on - prints out all events to stdout (can be very noisy!)
• event-monitor-off - turns off event monitoring
• event-monitor-timer - records incoming events for a specified period of time
• event-monitor - returns map of most recently recorded events
• event-monitor-keys - returns seq of all keys of recently seen events
• midi-capture-next-controller-key Returns the event key for the next modified controller
• buffer-write-relay - similar to buffer-write! but doesn't require native synth. Can be very slow.
• chord-degree - Returns the notes constructed by picking thirds in the given note of a given scale
• foundation-overtone-group - returns the group for the whole of the Overtone foundational infrastructure
• foundation-output-group - returns the group for output synths
• foundation-monitor-group - returns the group for the monitor synths (executed last)
• foundation-input-group - returns the group for the input synths (executed first)
• foundation-root-group - returns the main group for synth activity
• foundation-user-group - returns the container group for user activity
• foundation-default-group - returns the default user group - use this group for your synths
• foundation-safe-group - returns the safe group - synths in here will not stop when #'stop is called
• foundation-safe-post-default-group - returns the safe group positioned before the default group - synths in here will not stop when #'stop is called
• foundation-safe-pre-default-group - returns the safe group positioned after the default group - synths in here will not stop when #'stop is called
• node? - returns true if obj is a synth node or group
• node-live? - returns true if node is live
• node-loading? - returns true if node is loading (i.e. the server hasn't responded to say that it's loaded)
• node-active? - returns true if node is either loading or live

New macros

• with-no-ugen-checks - Disables ugen checks in containing form instead printing warning messages instead of raising exceptions. This is useful for the cases when the ugen checks are over zealous.
• with-ugen-debugging - Prints debugging information for the ugens within the containing form.

Removed fns

• on-trigger - prefer event system
• remove-trigger - prefer event system
• remove-all-handlers - calling this removes Overtone's default handlers rendering the system useless.

Renamed fns

• stop-midi-player -> midi-player-stop - It can now handle keys

New Insts

• supersaw
• dance-kick
• quick-kick
• haziti-clap
• daf-bass
• cs80lead
• simple-flute

New Synths

Started work porting synths from Ixi Lang (overtone/synth/ixi):

• impulser
• kick
• kick2
• kick3
• sampled-piano Now we also have a synth version of the sampled piano with support for :out-bus arg.

cgens

• sum - Adds all inputs together
• mix - Now divides the inputs signals by the number of number of inputs
• add-cents - Returns a frequency which is the result of adding n-cents to the src frequency.
• mul-add now auto-determins the correct rate.
• range-lin - maps ugens with default range of -1 to 1 to specified range
• poll - now implemented via send-reply to print out via Overtone stdout and remove flushing latency.

User Visible Improvements

• Further work on SuperCollider book translation (/docs/sc-book)
• out-bus argument now added to a number of synths. This should be considered standard practice.
• Overtone icon displayed on OS X systems
• tb303 inst now accepts :amp param
• Synth control proxies (args) can now accept a [default rate] vector i.e. [0 :kr]
• Allow following ugens to be foldable (following Clojure's semantics): #{"+" "-" "*" "/" "<" ">" "<=" ">=" "min" "max" "and" "or"}
• Teach certain binary ugens to behave appropriately if passed just one argument (unity).
• Default scsynth memory size is now 256 (up from 8mb!)
• env-gen now defaults to control rate.
• Event stream now also gets a generic MIDI event with the value as a payload rather than as part of the key
• Metronome now stores current bar
• Add chord :m7+9

• MIDI data map now includes keys :data2-f and :velocity2-f storing floats between 0 and 1
• Add more scales

• Midi poly player now sends both velocity (0-127) and amp (0-1)
• Midi poly player can now be associated with specific MIDI devices
• Midi poly player can now be created with a specific key allowing it to be removed independently

Internal Improvements

• SCUGen now stores the ugen spec

• extract-target-pos-args extraced for :tgt and :pos munging.
• Allow for different JVM args per OS
• Extend Integers to handle ISynthNode and IControllableNode protocols
• Fixed race condition in node creation where /s_new could occasionally trigger the handler fn before the ide id is added to active-synth-nodes*
• Synth names are now namespaced - allowing multiple synths to be defined with the same name but in different namespaces. Abbreviate safely to a 31 character limit.
• Teach synthdef-write to resolve tilde paths
• Internal event :osc-msg-received is now [:overtone :osc-msg-received]
• Freeing node ids is delayed by 1 second to reduce the chance of a race condition occurring in the case where the id has been recycled and used before the node status has been set to :destroyed.
• Add dynamic var overtone.sc.node/*inactive-node-modification-error* which may be bound to :silent, :warning or :exception to control the behaviour of the error created when an inactive node is either controlled or killed. (Default is :exception).

New Examples

• Examples now locate in overtone/examples
• Internal sequencer
• Getting started video transcript
• Jazz experiment
