What can be done with regular ZX Spectrum 48K and its BEEPER in... recording studio. :) The only instrument/sound-source and the only sequencer: ZX Spectrum 48K (BEEPER). ***The heavy post-production has been used.*** Recording-studio effects: track-by-track recording / filters / phasers / choruses / flangers / delays / echoes / reverbs / equalizers / compressors / limiters. PS: Here are original BEEPER sources without any post-production (to compare) - http://www.sendspace.com/file/m1z5ku - that's exactly what the song has been made of. But I don't know how long the files will be there!!
