Detailed Description

Sound effect playback with pitch control via SNESMOD.

Demonstrates standalone sound effect playback through the SPC700 using SNESMOD, without any background music. Five instrument samples are loaded from a soundbank at startup. Each button triggers a different effect, and the D-pad left/right cycles between three pitch settings.

Ported from PVSnesLib "effects" example by alekmaul.

SNES Concepts

• SPC700 effect playback: snesmodLoadEffect() + snesmodPlayEffect()
• Pitch control: SNESMOD_PITCH_LOW / NORMAL / HIGH
• Effects-only soundbank: .it file with instrument samples, no patterns
• Per-frame snesmodProcess() required even without music

What to Observe

• A/B/X/Y play different instrument samples
• L/R play cowbell
• LEFT/RIGHT change pitch (shown on screen)

Modules Used
