 "The Ephemeral Garden evokes the sense of convivial gatherings under a pergola. The murmur of conversation, complemented with the sound of animate matter. Growing plants, crackling wood, expanding rocks, crawling insects and the invisible signals emanating from all-pervasive electronic devices. Human and non-human voices intermingle. An ambience that is thick and alive, filled with liminal whispers otherwise unheard. Field recordings and synthetic sounds combine to create a continuously changing atmosphere. Beings come and go, the noise rises and subsides. The garden awakens with daylight, buzzes with activity throughout the day, then quietens at dusk. Its character adapting to the changing of seasons..."

+# Edit this file to introduce tasks to be run by cron.
+#
+# Each task to run has to be defined through a single line
+# indicating with different fields when the task will be run
+# and what command to run for the task
+#
+# To define the time you can provide concrete values for
+# minute (m), hour (h), day of month (dom), month (mon),
+# and day of week (dow) or use '*' in these fields (for 'any').#
+# Notice that tasks will be started based on the cron's system
+# daemon's notion of time and timezones.
+#
+# Output of the crontab jobs (including errors) is sent through
+# email to the user the crontab file belongs to (unless redirected).
+#
+# For example, you can run a backup of all your user accounts
+# at 5 a.m every week with:
+# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/

+// Streaming a File in From Disk
+
+
+// In some cases, for instance when working with very large files, you might not want to load a sound completely into memory. Instead, you can stream it in from disk a bit at a time, using the UGen DiskIn, and Buffer's 'cueSoundFile' method:
+
+		// (
+		// SynthDef("tutorial-Buffer-cue",{ arg out=0,bufnum;
+		// 	Out.ar(out,
+		// 		DiskIn.ar( 1, bufnum )
+		// 	)
+
+		// }).send(s);
+		// )
+
+
+		// b = Buffer.cueSoundFile(s,"sounds/a11wlk01-44_1.aiff", 0, 1);
+		// y = Synth.new("tutorial-Buffer-cue", [\bufnum,b.bufnum], s);
+
+		// b.free; y.free;
+
+
+// This is not as flexible as PlayBuf (no rate control), but can save memory.
