Posted in Darky, News | 2 Replies Franky Cartridge Enclosure. We hope to be able to release this card later this year. Programming and testing this pcb will take some time.
The ePSG stereo card has two stereo mini-jack outputs, one line-out and the other one is an amplified headphone output. An Atmel processor and Philips CLPD are used to control all hardware on this PCB. Registers are being made to access all PSG’s in MSX or ePSG enhanced mode, and to control the mixers and effect processor. In default mode our new cartridge will start in the MSX PSG compatible mode, with the second PSG on a different clockspeed to create a pseudo stereo effect, usable with all existing MSX software. For this a EEprom is also part of the PCB design. The audio end result of the mixed channels is fed into a SPIN FX-1 Effect processor, which has fixed effects such as echo, reverb, flange, chorus, etc. Also, the channel mixers used have some more functionality like treble, bass, equalizing and 3d stereo spatializing.īut that’s not all. The enhanced mode of the AY8930 adds separate envelopes for the three channels (as opposed to one shared envelope in the AY-3-8910), variable duty-cycles, more bits of precision for note frequency, volume, and envelope frequency, and a much better configurable noise generator.īut of course the main fact that it was backwards compatible with our MSX PSG made us thinking why not release a cartridge with this soundchip? And why not a cartridge with two new ePSG’s? Since these chips have separate outputs for each PSG-channel (even our MSX PSG has, but few MSX’s actually make use of this), we thought it would be nice to put each channel into a stereo mixer, so that each seperate channel can be mixed and placed into the stereo dept field (stereo panning). The fun thing about the AY8930 is that it has two different operating modes, one is AY-3-8910 compatible, and the other one is the enhanced mode.

Microchip actually released it, implementations were made for PC (the infamous Sound Master) and the design was also used in a few arcade systems. It was designed by General Instruments as an successor of the AY-3-8910 and sold to Microchip Taiwan together with their other chip designs. A while ago we stumbled upon an AY8930 sound processor. One of those was of course the lack of stereo sound in any MSX. Here at SuperSoniqs it is all about making our own “What if’s” possible. You know these questions that start with “What if?”.

Please note that you first need to install the Coolsoft MIDI Mapper and create a loopback port with the LoopMIDI driver before you can use the emulator as the global MIDI playback instrument under Windows 8 and up. There’s also a MT-32 emulator on Github (thanks Grauw).

The LoopMIDI driver to reroute programs that want to open hardware MIDI ports under Windows to your installed software synthesizers (e.g. Roland Sound Canvas vSTI obtainable as test or buy for 115 euro. Youtube video with the MIDI Player and S-YXG50 together:ģ.
Soundfont MIDI Player as better alternative for playing MIDI files You’ll also need a 5 pin din midi coupler to connect the MIDI-PAC cable to the pc midi cable, that can be bought for about $2.5, also at Aliexpress.Ģ.
Aliexpress sells them for around $5 including shipping. The vST MIDI-driver can be downloaded from ‘Mudlord’s Lair’.Īn USB to MIDI cable can be ordered from different sites. It’s wrapped in a vSTi (plug-in software standard for audio editing programs). To get it to work as a global MIDI device under Windows, you need to install a vST MIDI-driver. Basically it’s the software version of the MU-50 MIDI Sound Module. This shareware synthesizer was released by Yamaha in 2003 and supports XG and Roland GS extensions. It’s soundfont (sample based synthesis) based.Īnother option is to install the S-YXG50 software synthesizer. Coolsoft’s has also made available the Virtual Midi Synth, that can be downloaded from Coolsoft’s forum and it will add a new MIDI playback device under Windows. Then there are several ways to install a better software synthesizer. It can be downloaded from after registering for that forum.

There’s a default MIDI playback device installed in Windows, but the quality is low and it lacks a lot of professional features.įor Windows 8 and up, you need to install Coolsoft’s MIDI-Mapper. You’ll need a midi mapper to install alternative playback devices for playing MIDI. First of all, Microsoft removed support for extra midi mappers since Windows 8. There are ways to use your Windows PC as the MIDI playback device. If you have your Windows PC next to your MSX setup this tip we got might be for you.
