; SAMPLEPLAYASC (2011) for realtime Csound5 - by Arthur B. Hunkins
; SamplePlayASC.csd - ASCII keyboard only (no MIDI)
;  0-1 background loop, 1-25 single-shot samples. Mono or stereo, any sample rate.
;  May be a variety of uncompressed types including WAV and AIFF;
;   also Ogg/Vorbis (with Sugar 0.86/Blueberry or later, or Sugar 0.84/Strawberry
;   with updated libsndfile) but not MP3. Background loop must be named soundin.0,
;   and samples labeled soundin.1 and up.
;  They must be placed in the same folder as this file or they may be loaded
;   through the Journal (with Sugar 0.84/Strawberry or later).
; Note: in Sugar version, ` key triggers background loop.
