«ScoreClock, Patterns, RT/NRT and server-side resources» by jamshark70

on 12 Nov'11 03:20 in patternsnrtnonrealtimesync

A quick demo of one way to allocate server-side resources (SynthDefs, Buffers) that works in RT/NRT with minimal modification.

You'll need Jonatan Liljedahl's ScoreClock quark:

// Mac OSX / Linux

Quarks.install("ScoreClock");

// Windows, see http://swiki.hfbk-hamburg.de/MusicTechnology/883
