; FileMix4 (2010) for realtime Csound5 - by Arthur B. Hunkins
; requires MIDI device with 4-16(17) knobs/sliders; 4 files only
; 1-4 controls/parameters per file (amp, band-pass peak freq, peak gain, speed/freq)
; 1 parameter requires 4(5) knobs/sliders; 2 parameters, 8(9); 3 parameters, 12(13);
; 4 parameters, 16(17). The additional controller is optional Master volume.
; 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 to soundin.4, and in the same folder as this file.
