Ableton Link for Clojure

"Link is a technology that keeps devices in time over a local network, so you can forget the hassle of setting up and focus on playing music."

https://www.ableton.com/en/link/

overtone.ableton-link is a glue between the official open source c++ library and Clojure via JNA. This library provides precompiled binaries which have been tested on various computers.

Special thanks to 2bbb for his wonderful node-abletonlink

Supported platforms

• Windows x86_64 on JVM x86_64
• OsX x86_64 on JVM x86_64
• Linux x86_64 on JVM x86_64

(other platforms upon request, open a ticket)

Firewall

For Windows and Machintosh, make sure to accept the firewall dialog that appears as you enable ableton-link, for linux users that use firewall, make sure that port 20808 is open, with iptables this would be

iptables -A INPUT -p tcp --dport 20808 -j ACCEPT
service iptables restart

(to make iptable rule permanent, please use google)

API

overtone.ableton-link

• enable-link: [boolean] => nil If passed true, will enable link and network discovery, false for turning link off.
• link-enabled?: [] => booolean Returns true if link is enabled.
• get-beat: [] => number Reads from the clock and returns the current beat value.
• set-beat-now: [number] => nil Sets the current beat to a given value next time when all peers in sessions are togeather on same phase, if there's only one client in session, this will take effect immedietly.
• set-beat-at: [beat<number> timestamp<number>] => nil Sets the beat to a given value at a given timestamp, the timestamp should be in microseconds.
• set-beat-and-quantum-now: [beat<number> quantum<number>] => nil Sets the current beat and quantum to a given value next time when all peers in sessions are togeather on same phase, if there's only one client in session, this will take effect immedietly.
• set-beat-and-quantum-at: [beat<number> quantum<number> timestamp<number>] => nil Sets the current beat and quantum to a given value at a given timestamp, the timestamp should be in microseconds.
• set-beat-force: [number] => nil USE WITH CAUTION, this will set the current beat for all in session on a give value, will take effect immedietly and could cause disconinuity (may be anti-social behaviour).
• get-phase: [] => number Reads from the session and returns the phase of the beat.
• get-bpm: [] => number Reads from the session and returns the current bpm value
• set-bpm: [number] => nil Commits new bpm value to the session, takes effect immedietly.
• get-num-peers: [] => number Reads from the session and returns the number of peers connected.
• set-quantum: [number] => nil Commits new quantum to the session, quantum is the quantization of a bar, similar to division of a musical time signature.
