WaveTerrainPad v1.0 Author: Atte André Jensen (atte.dk), 2007 For background on the wterrain opcode see http://csounds.com/jmc/Articles/Wts/WTS.html This instrument consists of three stacked lines. Each line defines four points that the center point will move between at frequency "Roundtrip Freq" and with a certain radius. The terrain is build using the selected waveform. The first line is panned center, the second panned left and the third right. The panning is controlled by "width". Lines two and three can be detuned in relation to line 1. The resulting stereo signal is applied a single ADSR envelope. TIPS: * For more depth, run the instrument through a chorus effect. * The higher the "radius" the buzzier the sound. * The closer the points are to 0,0 git_instr_pad_wt_sine ftgen 0, 0, 1024, 10, 1
