TempoPlayer

Extension

Description

Outputs the current tempo in beats per seconds. All TempoPlayers share the same TempoBus, and so don't incur any additional resources.

The TempoPlayer is an input to the patch, and creates a TempoBus and supplies that control to the instr synth def. Move the tempo slider.( Instr(\helpTempoPlayer,{ arg tempo; tempo.dump; Impulse.ar( tempo ) },[ \tempo ]); Patch(\helpTempoPlayer,[ TempoPlayer.new ]).gui )

A TempoBus belongs to a specific server for its whole object-lifetime. A TempoPlayer is only told which server it is to play on when it is asked to prepare for play by its parent object. A TempoPlayer can be saved in a larger musical structure and that structure is capable of being played on disparate servers.

the symbol \tempo is registered in Spec.specs as a TempoSpec\tempo.asSpec.insp

whose defaultControl is a TempoPlayer\tempo.asSpec.defaultControl.insp=

so that the argname tempo in an Instr would by default result in a TempoPlayer for a Patch using that Instr.Patch({ arg tempo; Impulse.ar( tempo ) }).gui

execute this many times( Patch({ arg tempo; Impulse.ar( tempo ) },[ TempoPlayer.new ]).play(atTime: 1) )

Examples

You can also create the player inside the synth def:( Instr(\helpTempoPlayer,{ var t; t = TempoPlayer.new; // default global tempo Impulse.ar( t.kr ) }); Patch(\helpTempoPlayer).play(atTime:1) )

You can even just use Tempo.kr( Instr(\helpTempoPlayer,{ Impulse.ar( Tempo.kr ) }); Patch(\helpTempoPlayer).play(atTime:1) )
