void clock_driver::changetempo

(

signed8

period

)

[virtual]

Change tempo to period

• the current x should remain the same x = y * normalperiod / currentperiod y = x * currentperiod / normalperiod

virtual void clock_driver::init

(

)

[inline, virtual]

Initialize the driver by allocating necessary threads and data structures.

virtual void clock_driver::set_normalperiod_metarate

(

quad_period_type

newnormalperiod_metarate

)

[inline, virtual]

This function is called by the routines that can detect or modify the native tempo. When overriding this function, you should call the super class Beware: this method does not update the playing file and can be used for instance by the jack clock driver. The global set_normalperiod_metarate on the other hand will update the index file; which might not be wanted.
