One word of caution: The DAC module will have up to 20mV of low-end offset for the processor. While the converters are not as nice as dedicated ones (INL of 5 LSB, having to manually trim or auto-calibrate the output offset with bipolar supplies), they definitely do well for most average musical applications. 

Would one be better off just using a MCP4822 or MCP4922?
