This patch shows a simple way to control the balance between two sounds, and also illustrates the relationship between a) mixing two sounds to one location and b) panning one sound to two locations.

This example demonstrates creating a RAM buffer to hold a 10-second stereo recording, recording live audio into it (with input volume adjustment), and then playing randomly chosen backward clips of that sound, with a trapezoidal window to taper the beginning and ending of each clip to avoid clicks.

The timepoint object sends out a bang when the transport reaches a specified time position. This can be useful for causing something to happen—or for starting an entire process—at a particular instant during the transport's progress. A timepoint might, for example, even trigger a new time position value to be sent to the transport object itself, thus causing the transport to leap to a different time.

This patch does some of the same things as the "GlobalTransport" patch in the Extras menu, and shows what is likely going on behind the scenes in that patch. The toggle labeled "Start/Stop" starts the transport and immediately turns on the metro to begin triggering time reports. The button labeled "Rewind" sends a time position of bar 1, beat 1, 0 ticks to the transport to reset its time.

As you get more involved in programming audio, it's likely that you'll want to have multiple sound possibilities available in your program, that you can switch on and off as needed. You might want to take a look at MSP Tutorial 5: Turning signals On and Off to learn about some basic ways of doing that. However, that chapter leaves out the following pretty crucial issue.
