[sdiy] xr2206/xr2207

[patchell at cox.net]

The XR2206,XR2207, and the 8038 are all only suitable for LFO applications, in my opinion.  They do not have sufficient linearity for a pitch source.  the 8038 comes the closest.  If you do not care about accurate pitch, any of these will make nice oscilators.  The 2206 has some nice features, such as a built in multiplier for doing AM...
