[sdiy] Generating a large number of CV outputs

[Mike Bryant]

The current cost of passives amazes me.  Even 20 years ago I used a cent per component for all the non-special Rs and Cs as a guideline to price.

One question I have is, "How much reconstruction filtering is necessary?"

It was enough with an extra RC link directly after the mux cap, before the buffer op-amp. Added cost: ~0.008 $ per CV channel.
