Synthesizer Snapshot¶

Represents a synthesizer's current state, which can be saved and restored.

This can be useful for creating a different processor (for example, for rendering to an audio file) and copying the current processor's state.

Usage¶

A SynthesizerSnapshot is an interface, not a class. It is created by and applied to a SpessaSynthProcessor instance:

1
2
3
4
5

// Get the current state
const snapshot = synth.getSnapshot();

// Apply the state to the same or a different processor
synth.applySnapshot(snapshot);

Properties¶

midiChannels¶

An array of channel snapshots for all the MIDI channels of the synth.

keyMappings¶

An array of arrays of KeyModifiers.

Stored as:

1

const mapping = snapshot.keyMappings[channelNumber][midiNote];

systemParameters¶

All system parameters stored as a type: value pair.

midiParameters¶

All global MIDI parameters stored as a type: value pair.

reverbProcessor¶

A ReverbProcessorSnapshot of the reverb processor.

chorusProcessor¶

A ChorusProcessorSnapshot of the chorus processor.

delayProcessor¶

A DelayProcessorSnapshot of the delay processor.

insertionProcessor¶

An InsertionProcessorSnapshot of the insertion effect processor.
