Chip Tune is both a continuity from the haydays of music on old 80's personnal computer/consoles and a part of the retro-computer mouvement.
It started as most computers and consoles featured some sort of sound-chip.
It also evolved as games often featured music and sound effects, thus spawning a generation of professionnal personnal computers musician.
Contents
the AY-family scene
Amstrad 8 bit computers are part of the AY-family, along the ZX spectrum, most MSX and the Atari ST (which use a YM)
It is also to note that many arcade systems or some home consoles also included an AY-family chip, as it was cheap and easy.
Most used AY/YM computers
Many computers from the "AY/YM-family" included a MIDI port.
Atari ST (with its YM) is notable for its built-in Midi port, enabling music programation with Q-Base and spawning an entire generation of electronic home-musicians thx to the power of the 16+ bit, and the fun of a decent GUI.
The ZX spectrum 128 and the amstrad's Spectrum range(+2 and +3) also feature a Midi compatible port thanks to its RS232/Midi port.
MSX often featured such a Midi port, and were featuring a wide range of sound processors :
- MSX 1 : General Instrument AY-3-8910 soundchip
- MSX2 : Yamaha YM2149 (PSG)
- MSX2+ Optional sound chip: Yamaha YM2413 (OPLL) (MSX-Music)
- MSX TurboR (3) :
- Sound chip: Yamaha YM2149 (PSG)
- Sound chip: Yamaha YM2413 (OPLL) (MSX-Music)
- Sound chip: PCM
- 8-bit single channel (no DMA), 16 kHz max using BIOS routines.
- Microphone built-in
- Sound chip: MIDI in/out (FS-A1GT only)
It is to notice that MSX computers were released in the USA as music machines instead of home-computers, thus were a niche in the American home computer market.
Amstrad's limitations
Compaired to ZX spectrum 128 specs, the amstrad clearly failed to impose itself on the AY-scene.
- It lacks a built-in Midi Port.
as a result, an external peripheral is needed, being somewhat less reliable than a directly built-in connector.
- It has heavier graphics.
the 10Ko differencesof needed graphic RAM betwen Speccy and CPC makes a lot of difference. Of course you could manage a better Ram by disabling the screen display, yet this can't allows the use of the computer as a direct Musical instrument/mixing station.
Also the fact that ZX spectrum 128 and +2 and +3 were all supplied with 128Ko Ram while CPC/Plus ranges still included 64ko Ram computers (464-664).
Despite being quite cheap, the 464 couldn't compete.
As a result, no Chip-Tune bands actually use an Amstrad computer for live performances (but the ZX spectrums from Amstrad...)
This is somewhat of a shame, as the 6128+ would be a good machine for such purpose thanks to it's DMA channels and the possibility to put software on Cartridge/Rom.
Also as most ChipTune bands also feature video projectionsfrom the used computer in Live-performance, the CPC would shine too thx to its somewhat better graphic ability.
AY Chip-Tune Live performances
Here some exemples of AY live performances.

other kind of ChipTune performances
- The following exemples are live performances of computer's game classics, yet played on more traditionnal instruments and mostly inspired by C64 versions (yet you may recognise the songs from CPC too...).

This one is played by a "classical" orchestra, of very popular formula.
- Nintendo's Game Boy
Some cartridges and softwares allows to use most of Nintendo's portable consoles as live instrument or Remix effects generators.
Because such consoles are cheap and easy to transport, having an in-built video display, and being iconic of the 8bit or digital era, this is quite popular. {{#ev:youtube|tYBHpN6gSTw|300}} http://www.youtube.com/watch?v=tYBHpN6gSTw
It is to notice that even a Speak & Spell (Texas Instrument) or any good old retrogame featuring some sort of Sound processor can be turned into a digital instrument.
This is called circuit bending.
