Csound Ex 1, pp. 7-8

1. Render the Csound orchestra and score files: etude1.orc & etude1.sco.
2. Play and listen to the different sound qualities of each instrument.
3. Modify the score file and change the duration of each note.
4. Make all the notes start at the same time.
5. Comment out several of the notes so that they do not "play" at all.
6. Cut and Paste multiple copies of the notes, change the start times (p2) and duration (p3) of the copies to make the same instruments start and end at different times.
7. Create a canon at the unison with instr 106.
8. Look up and read about the opcodes used in instr 101 — 106 in the Csound Reference Manual.
   • ar oscil xamp,xcps, ifn[, iphs]
   • ar foscilxamp,kcps, kcar, kmod, kndx, ifn[, iphs]
   • ar buzz xamp,xcps, knh, ifn[, iphs]
   • ar pluck kamp,kcps, icps, ifn, imeth[, iparm1,iparm2]
   • ar grain xamp,xpitch,xdens,kampoff,kpitchoff,kgdur, igfn, iwfn, imgdur
   • ar loscilxamp,kcps, ifn[, ibas][, imod1, ibeg1, iend1][,imod2,ibeg2,iend2]
9. In the orchestra file, modify the frequency and amplitude arguments of each instrument.
10. Change the frequency ratios of the carrier and modulator in the foscil instrument.
11. Change the number of harmonics in the buzz instrument.
12. Change the initial function for the pluck instrument.
13. Change the density and duration of the grain instrument.
14. Make three copies of f 4 and renumber them f 5, f 6 and f 7. Load in your own samples ("yoursound1.aif," "yoursound2.aif," "yoursound3.aif"). Create multiple copies of instr 106 and number them instr 66, instr 67 and instr 68. Edit the instruments so that they each "read" a different soundfile at a different pitch. Play the different samples simultaneously.
15. In the file etude1.orc duplicate and renumber each duplicated instrument. Set different parameter values for each version of the duplicated instruments. Play all twelve instruments simultaneously. Adjust the amplitudes so that you have no samples the duplicated instruments.
