New and improved DMX GENMIDI for Doom and sourceports, taking full advantage of
|
|
the OPL3 waveforms. This takes things up a notch in terms of timbre.
|
|
|
|
# Summary
|
|
This is a GENMIDI patch for DMX for OPL3 FM synthesis. This patch aims to remedy
|
|
the "weak" default instruments to better match the Roland Sound Canvas, most
|
|
notably the SC-55 and SC-88. Recommended minimum setup for no note-cuts is
|
|
ZDoom 2.8.1 with DOSBOX OPL3 emulator core, with 6 chips emulated.
|
|
|
|
======FAQ======
|
|
# Why OPL3 only?
|
|
OPL3 has four additional waveforms - Alternating Sine, Camel Sine, Square, and
|
|
Logarithmic Square (Sawtooth). The most interesting of these is the Square wave,
|
|
for obvious reasons! This will benefit percussion instruments immensely.
|
|
|
|
# What did you use for this project?
|
|
|
|
Hex Editors, OPL3 Bank Editor, Fraggle's Python scripts, Adlib Tracker II,
|
|
Edlib, ADLMidi. I also used the following keyboards and devices:
|
|
|
|
- Yamaha PSR-3 for basic voice ideas
|
|
- Yamaha PSS-50 for layered voice ideas
|
|
- Yamaha DX-7
|
|
- Commodore 64 Music Module
|
|
- VRC7 and related chips
|
|
- Sound Blaster 16
|
|
- Yamaha PCI cards
|
|
- Sounds from various SEGA MegaDrive games

=======WOPL FAQ=======
|
|
# What's the difference between the WOPL version and the DMX version?
|
|
The main difference is with a few instruments that had to be tweaked to work
|
|
with DMX. Most of these changes are negligible for General MIDI stuff. To hear
|
|
what I intended DMXOPL to sound like in Doom, you'll have to wait for Eternity
|
|
Engine's ADLMIDI support to be finalized.
|
|
|
|
# Any plans for GS/XG support?
|
|
Yes. This will take considerable time, and voices will be added as I come across
|
|
them in my MIDI files. You can check the progress on those through the XG and GS
|
|
branches that I will make (or have already made). As I think the GM set is solid
|
|
enough now, save for just a handful of instruments, I can start work on the
|
|
other banks.
|
|
|
|
# Will the WOPL version be usable on any other FM chips?
|
|
Depends on the chip, but more than likely the answer is no. YMF262 (and the OPL*
|
|
family for that matter) operate differently than most of the other FM chips, and
|
|
wouldn't likely transfer over to DX-7 or other instruments without considerable
|
|
work, if they would work at all.
|
|
|
|
|
|
# Is the best way to listen to this really through an emulator?
|
|
Yes, unfortunately. Unless someone makes an FM chip that can handle 128+
|
|
channels, this is likely never to change. If you're using this in your music
|
|
projects and you still want to use the real thing, I recommend recording one
|
|
track at a time and throwing the result in your favorite DAW - just be sure to
|
|
put a highpass filter set to a really low value (I recommend 5 Hz) to get rid
|
|
of the offset garbage, lest your mix splatter like crazy.
