; FileMix4ASC (2010) for realtime Csound5 - by Arthur B. Hunkins
; ASCII keyboard control (no MIDI); 4 files only
; 1-4 controls/parameters per file (amp, band-pass peak freq, peak gain, speed/freq)
; Files must be stereo; can have different sample rates, may be a variety of
; uncompressed types including WAV and AIFF; also Ogg/Vorbis (with Sugar 0.86/
; Blueberry or later) but not MP3.
; They must be named soundin.1 through soundin.4, and in the same folder as this file.
