- Amiga tone (both coarse and fine E/F pitch slides). The `slideArg` is a **raw tracker period-unit count** (no scaling), with sign matching linear mode (negative for E, positive for F). Coarse slides apply on every non-first tick; fine slides apply once on tick 0 — the per-step arithmetic is identical:
- AMIGA_BASE_PERIOD = 428.0 (period at the Taud reference pitch C4 for a standard 8363 Hz instrument, NTSC clock — identical to PT "C-2" period 428)
- period = AMIGA_BASE_PERIOD × 2^(−(noteVal − C4) / 4096)
