Pbindef modifies individual keys of a running Pbind without restarting the stream

While Pdef replaces an entire Pbind pattern on re-evaluation, Pbindef allows changing individual keys of a named Pbind without affecting the others. Pbindef(\name, \key, newValue) updates only that key, leaving all other keys unchanged in the running stream. This is the most surgical live-editing approach — useful when one parameter needs to change but the overall rhythmic structure should persist. Pbindef is a special case of Pdef; both maintain state across re-evaluations. To remove a key from a Pbindef, set it to nil.

Examples

Pbindef(\seq, \freq, 440); // change only freq while seq keeps playing Pbindef(\seq, \amp, 0.5); // change only amp Pbindef(\seq, \freq, nil); // revert freq to Pbind default

Assessment

You have a Pbind playing through Pdef. You want to change only the frequency pattern without restarting any other patterns. Should you use Pdef or Pbindef? Describe the difference.
