# render_opl.sh — render tunes through OPL3 FM (authentic Sound Blaster
|
|
# flavour, no soundfont). Usage:
|
|
# ./tools/render_opl.sh [tune.mid ...] (default: all midi/*.mid)
|
|
# OPL_MODEL=4 ./tools/render_opl.sh ... (4 = Apogee/Duke Nukem volumes)
|
|
#
|
|
# Volume models: 2 NativeOPL3 (id-style) 3 DMX (Doom, default)
|
|
# 4 APOGEE (Duke Nukem 3D) 8 AIL 10 HMI
