MainController

The grand central station of HISE.
The MainController class represents the instance of a HISE project and can be used to access quasi-global data / methods.
It is divided into multiple sub-classes which encapsulate different logic in order to bring some order into the enormous task of handling everything:

• the SampleManager subclass handles pooling / preloading of samples
  
• the MacroManager (which itself has multiple subclasses) handle all automation / MIDI controller tasks
  
• the UserPresetHandler takes care of the loading / browsing of user presets.
  

Implementations of this class are also derived by the juce::AudioProcessor and some other helper classes. Check out the hise::FrontendProcessor class for actual usage in a C++ HISE project.
Most classes just want a reference to the MainController instance. If you want to use it in your C++ classes, I recommend subclassing it from ControlledObject , which exists for this sole purpose.

Class methods

compileAllScripts

void compileAllScripts()

Compiles all scripts in the main synth chain

allNotesOff

void allNotesOff(bool resetSoftBypassState=false)

Call this if you want all voices to stop.

beginParameterChangeGesture

void beginParameterChangeGesture(int index)

same as AudioProcessor::beginParameterGesture().

endParameterChangeGesture

void endParameterChangeGesture(int index)

same as AudioProcessor::beginParameterGesture().

setPluginParameter

void setPluginParameter(int index, float newValue)

sets the plugin parameter to the new Value.

getUptime

double getUptime() const noexcept

Returns the uptime in seconds.

getBpm

double getBpm() const noexcept

returns the tempo as bpm.

skin

void skin(Component &c)

skins the given component (applies the global look and feel to it).

addTempoListener

void addTempoListener(TempoListener *t)

adds a TempoListener to the main controller that will receive a callback whenever the host changes the tempo.

removeTempoListener

void removeTempoListener(TempoListener *t)

removes a TempoListener .

getMainSynthChain

ModulatorSynthChain * getMainSynthChain()=0

this must be overwritten by the derived class and return the master synth chain.

getCpuUsage

float getCpuUsage() const

Returns the time that the plugin spends in its processBlock method.

getNumActiveVoices

int getNumActiveVoices() const

Returns the amount of playing voices.

isInitialised

bool isInitialised() const noexcept

This returns always true after the processor was initialised.

setGlobalPitchFactor

void setGlobalPitchFactor(double pitchFactorInSemiTones)

This sets the global pitch factor.

getGlobalPitchFactor

double getGlobalPitchFactor() const

This returns the global pitch factor.
Use this in your startVoice method and multiplicate it with your angleDelta.

getGlobalPitchFactorSemiTones

double getGlobalPitchFactorSemiTones() const

This returns the global pitch factor as semitones.
This can be used for displaying / saving purposes.
