Preferred way to switch Signals

[Highcooley]

Hey guys,

 

I am wondering what your preffered way for switching CV and audio signals with DOUTs is. So far, relays (in combination with power shift registers), FETs or digital switches come to mind. Relays aren't as compact and power saving as the other two options. On the other hand, I fear distortion and signal voltage level problems with digital options.

 

If you go the digital way, can you recommend certain parts which you use and do the job best?

 

In my case, I have two problems to solve. One is switching certain VCO modes like AUDIO/LF as well as feeding back outputs of other VCOs for syncing and FM. The other problem is a modulation matrix, where I have 8 modulation sources, 8 destinations as well as 4 shaping sources. Here I could think of an audio matrix switch. But which one to chose as there are virtually hundreds with different features and in different price ranges?

 

 

Sorry, if this topic was discussed before. Since the forum's search option is still down, I tried to search manually without success.

 

Cheers

Since nobody seems to have an opinion on this topic, I quickly sum up what I plan to go for:

 

Signals lower than -5V --> relays --> no suitable digital switch found in a normal price range

Audio path --> relays --> no distortion

Critical CV signals (e.g. note CV) --> relays --> no distortion

Uncritical CV signals in the positive voltage range (0-10V) --> CD4051 and CD4053 --> cheap, compact, easy to drive, energy efficient

Uncritical CV signals in the range of -5 to +5V --> CD4066 --> cheap, compact, easy to drive, energy efficient

Single CV signals on a board --> relay --> no suitable solution found yet
