void FluidS::Fluid::set_gen2	(	int	chan,
		int	param,

	)

Change the value of a generator.

This function allows to control all synthesis parameters in real-time. The changes are additive, i.e. they add up to the existing parameter value. This function is similar to sending an NRPN message to the synthesizer. The function accepts a float as the value of the parameter. The parameter numbers and ranges are described in the SoundFont 2.01 specification, paragraph 8.1.3, page 48. See also 'fluid_gen_type'.

Using the fluid_synth_set_gen2() function, it is possible to set the absolute value of a generator. This is an extension to the SoundFont standard. If 'absolute' is non-zero, the value of the generator specified in the SoundFont is completely ignored and the generator is fixed to the value passed as argument. To undo this behavior, you must call fluid_synth_set_gen2 again, with 'absolute' set to 0 (and possibly 'value' set to zero).

If 'normalized' is non-zero, the value is supposed to be normalized between 0 and 1. Before applying the value, it will be scaled and shifted to the range defined in the SoundFont specifications.

start_voice()

void FluidS::Fluid::start_voice

(

Voice *

voice

)

Kill all voices on a given channel, which belong into excl_class. This function is called by a SoundFont's preset in response to a noteon event. If one noteon event results in several voice processes (stereo samples), ignore_ID must name the voice ID of the first generated voice (so that it is not stopped). The first voice uses ignore_ID=-1, which will terminate all voices on a channel belonging into the exclusive class excl_class.
