• 3 octaves (C-1 to B-3) with pitch control via 8.8 fixed-point multipliers
• Pattern-based sequencing with variable-length event encoding
• Real-time audio preview that closely matches Atari hardware output
• Export to Atari executable (.XEX) via MADS assembler
• Self-contained project format (.pvq) with embedded samples
• Multi-format audio import WAV, MP3, OGG, FLAC, M4A, and more
• Timing analysis to verify IRQ cycle budget before export
