AI Analysis

●●●BangerWizardryNiche Gem

Real-time guitar-to-MIDI harmony with proper counterpoint rules and sub-10ms latency.

Strengths
  • •Encodes music theory rules like parallel fifth rejection into the engine.
  • •Single-cycle pitch detection achieves latency low enough for live performance.
  • •Cross-platform Rust core runs natively, in browser, or server-side.
Weaknesses
  • •Guitar-to-MIDI conversion remains historically unreliable despite latency improvements.
  • •Niche appeal limited to musicians specifically interested in counterpoint harmony.
