If you want to learn how to use a handful of basic operators, have a look at the [workshop](WORKSHOP.md). - -## General - -- On **OSX**, setup [IAC virtual MIDI buses](https://help.ableton.com/hc/en-us/articles/209774225-Using-virtual-MIDI-buses). -- On **Windows**, setup [loopMidi](http://www.tobias-erichsen.de/software/loopmidi.html). -- On **Linux**, setup [qjacktl](https://qjackctl.sourceforge.io/). - -## Pilot - -[Pilot](https://github.com/hundredrabbits/Pilot) is a minimalist synth software designed to work via UDP, and to quickly get started with Orca. This **requires no setup**, as long as both applications are open, they should be able to communicate with each other. - -- Launch Orca & Pilot. -- In Orca, make sure that UDP is pointing to port `49161`. -- Bang something like `;03Cff` to [play a note](https://github.com/hundredrabbits/pilot#play). -- Bang something like `;revff` to [add reverb](https://github.com/hundredrabbits/pilot#effects). - -## Ableton Live - -To send [Midi notes](https://github.com/hundredrabbits/Orca#midi) to [Ableton Live](https://www.ableton.com/en/) instruments, bang the Midi operator `:`, like `:03C` to send to _Channel 1, Octave 3, Note C_. Have a look at [midi.orca](https://github.com/hundredrabbits/Orca/blob/master/examples/_midi.orca) to see it in action. - -- Launch Ableton Live. -- Create a new **midi instrument** track. -- Select `IAC Driver(Bus 1)`(OSX), or `LoopMidi`(Windows), in the instrument's inputs dropdown. -- Activate the **In** toggle, on the instrument track. - -## SonicPi - -To send [OSC messages](https://github.com/hundredrabbits/Orca#osc) to [SonicPi](http://sonic-pi.net), select [port 4559](https://github.com/hundredrabbits/Orca#osc). SonicPi listens to the address defined in `sync`, to send to the `live_loop`, bang the OSC node `=`, like `=a`. Have a look at [sonicpi.orca](https://github.com/hundredrabbits/Orca/blob/master/examples/software/sonicpi.orca) to see it in action.

To draw lines on Dotgrid, you need to bang the UDP node `;` with different [commands](https://github.com/hundredrabbits/Dotgrid/blob/master/desktop/sources/scripts/listener.js).

Orca will never include domain specific operators to generate music or to create pictures. It is designed to be as generic as possible. - -## Golf - -### Modulo - -Will output the modulo of `6 % 4`. - -``` -1X. -6I4 -``` - -### Uppercase - -Will output uppercase `C`. - -``` -cA1. -.dAZ -``` - -### Lowercase - -Will output lowercase `C`. - -``` -H.. -CM1 -``` - -### Substract - -Will substract `8 - 3`. - -``` -.3Mz -8Ax. -``` - -### Not Null - -Will bang if not null. - -``` -cYc -J.J -cFc -``` - |
