[sdiy] Newbie capacitor questions 2 - Return of the Cap.

[Theo]

I've used ceramics (47n NP0) for LFO and found no problems.
Think VCO should be fine too the LFO's go into audio range without trouble.

Not NP0 but Murata hi-cap series can be quite fun and let you use a 1206 or
0805 10u/25V ceramic instead of a elco.
The 10V and 6,3V parts even go up to 100u.
Didn't test these parts for envelope use though...
