distortion creeps in under 200Hz

> g_01 = X.dpw3Tri AR (xLine KR 2000 20 10 DoNothing) * 0.1

very fast sweeps can have transient distortion effects

> g_02 = X.dpw3Tri AR (mouseX KR 200 12000 Exponential 0.2) * 0.2

compare

> g_03 = lfTri AR (mouseX KR 200 12000 Exponential 0.2) 0 * 0.1

less efficient than LFTri
