PSG
PSG (Programmable Sound
Generator) is the sound chip
that you will find in all MSX and MSX-related
machines :
- in MSX and SVI machines, it's the General
Instruments AY-3-8910 sound chip
- in MSX2, MSX2+ and MSXturboR machines, it's
generally replaced by the Yamaha YM2149 sound
chip
- in Coleco and Sega machines, it's the Texas
Instrument SN76489 sound chip
It has three tone generators and a white noise
generator.
The MSX-BASIC includes instructions to use easily
the PSG.
With some advanced programming; PSG can be used
to produce 8-bit samples : http://map.grauw.nl/articles/psg_sample.php
This part of the audio mixer shows only the
normal using of the PSG channels. If the PCM part
is used, then it will be displayed in the PCM
part of the audio mixer.
Stereo
As SCC is combined is PSG in some demos and
Konami games, it gives a stereo effect, that you
can enhance by a fine tuning in the mixer
Hear only PSG
- de-select the other soundchips in the mixer
- if you hear nothing, then take a look below
Hear PSG in stead of other soundchips
- de-activate the MSX-MUSIC emulation and/or the
MSX-AUDIO emulation in the Options/Sound menu
- use the MSX2 Only PSG machine, especially if
you want to run a game with automatic choice
between PSG and MSX-MUSIC, but want to hear the
PSG sounds in stead of MSX-MUSIC.
You can view on this
page the list of the rom games with automatic
choice between PSG and MSX-MUSIC.
