Konnichiwa! ;)
The music has been composed for ZX Spectrum 16K with AY-interface, however I made all the work on ZX Spectrum 48K with the same interface and also I recorded the stuff from this machine.
Each source of the songs is not bigger than....... 4,8Kb!!!!!! ;)
Software used: ZX SoundTracker 1.1.
I make chiptunes on ZX Spectrum computer since 1989. Its AY chip offers 4-bit sound, 3 channels + white noise generator, square wave and several 'buzzers'. Or 3 channels of 4-bit digital sound, but then I have to fit all samples in 48Kb of RAM. :) My other machines: Amiga 500, Amiga 1200, Atari Falcon 030, NES/Famicom, Raspberry Pi and others. The bands I founded: AY-RIDERS and also YM-DIGITAL.
