TOOT 14

Throughout these TOOTS, separate score and orchestra files were used. However, today it is probably more common to write a single Unified Csound code file, called a CSD. If we look again at TOOT 1, we have the following files

File: Toot01.orc

instr 1 a1 oscil 10000, 440, 1 out a1 endin

File: Toot01.sco

f1 0 4096 10 1 ; use GEN10 to compute a sine wave ;ins strt dur i1 0 4 e

A CSD containing both orchestra and score above will look like this:

File: Toot14.csd

<CsoundSynthesizer> <CsInstruments> instr 1 a1 oscil 10000, 440, 1 out a1 endin </CsInstruments> <CsScore> f1 0 4096 10 1 ; use GEN10 to compute a sine wave ;ins strt dur i1 0 4 e </CsScore> </CsoundSynthesizer>

For writing Csound code on OLPC, we would strongly advise that CSDs are used, as they are more compact and self-contained.
