オリジナル曲「LONELY RIDER」 Fujitsu FM77AV Version

Published on Mar 25, 2020 NozMusic

"2014年10月に発表したオリジナル曲「LONELY RIDER」を、2020年3月にFujitsuパソコンFM77AVでリメイクしました。
音楽制作にあたり、標準のF-BASICをOH!FMの拡張PLAY文「EDPLAY」に拡張しました。
これにより、自作音色を自由に切り替える事ができまして、貴重なFM音源3音を有効活用出来ました。
PSG音源も、ソフトエンベロープが追加されてるので、エンベロープを切り換えながら演奏させてます。
更にパートデチューンも使えるので、PSG音源2音を重ねてコーラス感あるサウンドを作れます。
32年ぶりにFM77AVでMMLを打ちましたけど、まだまだ出来るものですね♪"

Googlish:

"The original song 'LONELY RIDER' announced in October 2014 was remade in March 2020 with the Fujitsu PC FM77AV.
For music production, the standard F-BASIC has been extended to OH! FM's extended PLAY statement 'EDPLAY'.
This made it possible to freely switch between self-made sounds, and effectively used three precious FM sound sources.

The PSG sound source also has a soft envelope added, so we play while switching the envelope.
In addition, part detune can be used, so you can create a chorus-like sound by layering two PSG sound sources.
I wrote MML with FM77AV for the first time in 32 years, but I can still do it ♪"

via Wikipedia:

"The FM-7 ('Fujitsu Micro 7') is a home computer created by Fujitsu. It was first released in 1982 and was sold in Japan and Spain. It is a stripped-down version of Fujitsu's earlier FM-8 computer, and during development it was referred to as the 'FM-8 Jr.'.

Although it was designed to be a cut-down version of the FM-8, most notably removing the (expensive) bubble memory technology, the FM-7 was given a more advanced AY-3-8910 sound chip capable of three voice sound synthesis, leading to a strong uptake among the hobbyist computer market in Japan and making it a more popular system than the FM-8."

And via Wikipedia here:

"The AY-3-8910 is a 3-voice programmable sound generator (PSG) designed by General Instrument in 1978, initially for use with their 16-bit CP1610 or one of the PIC1650 series of 8-bit microcomputers. The AY-3-8910 and its variants were used in many arcade games—Konami's Gyruss contains five[1]—and pinball machines as well as being the sound chip in the Intellivision and Vectrex video game consoles, and the Amstrad CPC, Oric-1, Colour Genie, Elektor TV Games Computer, MSX, and later ZX Spectrum home computers. It was also used in the Mockingboard and Cricket sound cards for the Apple II and the Speech/Sound Cartridge[2] for the TRS-80 Color Computer."

"At the Gesprächskonzert in the Superbooth19 Auditorium in Berlin's FEZ, Markus from Ploytec demonstrates a prototype unit of the PL2 Logos, emulating the General Instruments CTS256-AL2, the 'text to speech' companion chip for the SP0256-AL2 speech synthesizer from the eighties."

EXPERIMENTAL SYNTHESIZER BASED ON AY-3-8910 CHIP

"This auction is for an experimental synthesizer based on the General Instruments AY-3-8910 Programmable Sound Generator chip. The AY-3-8910 chip was used extensively in the early to mid 1980's as the main sound generator on a large number of commercial coin-operated video games. This chip has remained elusive to most since the extended data sheet is hard to come by. The chip was first manufactured by General Instruments from the late 1970's until the late 1980's, then a few were made by Microchip Technology. Early in the 1990's a pin-for-pin and functionally identical version was manufactured by Yamaha and sold under the part number YM2149F.

This experimental unit breaks out each and every register used on the AY-3-8910 into switches and controls so the user can manually adjust each of the three tone generators and the envelope control by means of control panel knobs. In addition, the unit is pre-programmed to work via a 61-key keyboard through the Lupine Systems Series 400 Keyboard Interface Board (included but not pictured). This interface board allows the user to connect any single pole un-matrixed keyboard to the unit. The programming is set up to assimilate each keystroke into the appropriate musical note assigned to each key. The user may shift the octave up and down by 1 on each of the three generators. The user may also select from the pre-programmed musical scale tuning or variable off-key tuning or a fixed frequency note.

Full envelope control is provided through the AY-3-8910 envelope generator. Included with the unit and pre-wired is one Lupine Systems Series 400 Filter/Modulator which provides basic LPF function and a LFO for modulation control.

The unit also has full control over the way the keyboard is scanned and processed, including an arpeggiator and key repeat/scan direction control. The speed in which the keys repeat along with the pulse width of the trigger can be adjusted to create a variety of unique sounds.

The unit outputs sound via four RCA jacks, one for each AY-3-8910 audio channel (A, B, C) and one "composite" output, which is an even mix of A+B+C. The unit also outputs a TTL compatable trigger for external triggering functions.

An expansion interface is also included which originally was used for a MIDI interface and to operate a YM2413 based voice unit.

Included with this auction is the entire experimental unit, one Lupine Systems Series 400 Interface Module for Parallel (unmatrixed) Keyboards, one 26-pin ribbon cable (which connects the unit to the Interface board), and a set of schematics. The schematics are for the Lupine Systems Series 400 Mini, which is very very very close to this unit but some of the pin numbers for the connectors may not be the exact same. A copy of the software for the PIC16F73 microcontroller is also included on CD-ROM in MPASM (assembly) format so you can see how the processor does its thing.

Keyboard is NOT included with this auction! Any 61-key keyboard (or fewer keys say 48 key is common on old organs) will work as long as it is NOT matrixed (multiplexed) and has individual switches for each key with a common ground bus."

I created a new General Instruments label for these moving forward. There was one post featuring the AY-3-8910 from Little-Scale back in 2011 here.

It was also produced under license by Yamaha (with minor modifications, i.e. a selectable clock divider pin, and a double-resolution but double-rate volume envelope table) as the YM2149F."

It's also used in the The MIDIbox AY V1: "The MIDIbox AY V1 is stuffed with a General Instruments AY-3-8912 sound chip..."
