[sdiy] VCO waveform logic selection

Hi guys,

Let's say I have a vco module that outputs various waveforms at +-5V.
And I want to digitally select 1 of these ouputs to send it to the input

of another module. What is the best way to proceed ?

would some analog mux like the 4051 do, if its power supply is set
to +-7.5V ? If yes, how to handle logic selection signals, especially
if they're generated by 3V logic uC ?

Thanks in advance,
