This is a standalone application for performing Terry Riley's In C, developed in Max 7 by the Loyola University Technology Ensemble for laptop orchestra performance or similarly technology-augmented musical vehicle.
It comes with everything a performer will need, including a changeable ostinato pulse, MIDI output support, as well as a built-in synthesizer. All of these features can be controlled directly from a computer keyboard, but if you're feeling more intrepid use this patch as a launching point for developing new synthesizers or using other external controllers.
Current releases can be found here, with direct links found below.
Building a new version of this application requires a copy of Max 7. Start
by opening the *.maxpat file at the root of the repository and exporting the
patch is a standalone, not a Max collective:
Due to a path bug in Max as of version 7.3.5, some required resources need to
be manually copied into the app bundle after building the standalone. Copy all
images in media/, MIDI files in sequences/, and all resources in Extra/
to the following path, depending on OS:
Windows: <standalone folder>\resources\misc
macOS: <standalone bundle>/Contents/Resources/C74/misc
To get to "Contents", right click the resulting *.app file
and click "Show Package Contents".
The application has been assembled correctly if phrase playback works correctly and the staff images change when a new phrase is selected.
