[sdiy] DC Offset Injector?

[Joe Kramer]

Hi Friends,

My MS20 LFO generates a +/- 2.5v triangle wave, and this is fine for most
of the internally patched functions.  But once you start patching out, there is
an obvious need for a zero-to-5v wave, for instance when modulating one
VCO against the ring modulator.

Can I make a passive DC offset injector with, say, 10k resistors and
pots and a power source--basically a mixer with the LFO as one input and
a DC voltage as the other input?  If so, is 10k a safe all-around value?

Or do I have to use an amplifier to do this?

Thanks,
Joe
