Detailed Description

Sample-based oscillator with pitch tracking and looping capabilities.

SampleOscillator plays back audio samples at different pitches, similar to a sampler. It supports looping, bidirectional playback, sample range selection, and automatic resampling to match the target pitch.

Key Features:

Pitch-shifted sample playback (follows MIDI note input)
Loop modes: forward, backward, ping-pong
Configurable loop points and sample range
Automatic high-quality resampling
Crossfade support for smooth loop transitions
Note on/off triggering

Direction Modes:

forwards: Normal forward playback
backwards: Reverse playback
pingpong: Alternates between forward and backward

Usage:

SampleOscillator osc;
osc.setSampleRateAndBlockSize(44100.0, 512);
osc.setSample(&mySample);
osc.setLooping(true, 1000, 5000); // Loop between samples 1000-5000
osc.setDirection(SampleOscillator::forwards);
osc.noteOn(); // Trigger playback
 
// Pitch-shifted playback - plays at MIDI note 60 (C4)
bool isStillPlaying = osc.read(60.0, audioBuffer);
