Detailed Description

Generic MIDI-1 polyphonic synth framework.

Synthesiser<Voice> owns a fixed-size pool of Voice instances (subclasses of SynthesiserVoice) and routes MIDI events into them, with a configurable voice-stealing strategy when the pool is exhausted.

Relationship to MPE: MpeVoiceAllocator (in mpe_synth_voice.hpp) is the MPE-aware counterpart that routes per-note expression across MPE member channels. Synthesiser is the plain-MIDI alternative — one note per channel/note pair, channel-level pitch bend / aftertouch / CC apply to every active note on that channel.

Use Synthesiser when the descriptor sets supports_mpe = false (the default for non-expressive synths).
