Members KingVidiot Posted June 6, 2008 Members Share Posted June 6, 2008 Anyone have experience hooking up a synth or a microphone to an oscilloscope to view the waveforms (audio signal or even control voltage)? I guess I can use basic BNC to RCA connectors to make the connections, but I have no idea what settings to use on the scope. I bought it pretty cheaply second-hand, and I think it will be better than the PC-based ones that have too much latency. Any suggestions? I couldn't resist after the cool demos I saw on matrixsynth recently. Link to comment Share on other sites More sharing options...
Members OPEN OCEAN Posted June 6, 2008 Members Share Posted June 6, 2008 nope but reminds of 50s b movies so it cant be bad at all haha.... Link to comment Share on other sites More sharing options...

Tweak it out until it looks good. Link to comment Share on other sites More sharing options...

Your scope will live longer and you might actually get something on the screen. :lol: Link to comment Share on other sites More sharing options...

Members DINpluggedIN Posted June 6, 2008 Members Share Posted June 6, 2008 i.e. Nice exponentially-decaying toneburst riding on that reverse sawtooth. Link to comment Share on other sites More sharing options...
Members Qwave Posted June 6, 2008 Members Share Posted June 6, 2008 i.e.... Nice single osc sawtooth with lot of resonance. Link to comment Share on other sites More sharing options...
Members Awake77 Posted June 6, 2008 Members Share Posted June 6, 2008 I use a software-based harmonic analyzer (Freakascope) a lot when designing patches, or trying to match a particular sound. Latency isnt an issue and it works great, but Id like to get a hardware scope at some point, just because it looks so damn cool! Link to comment Share on other sites More sharing options...

If you think of harmonic analyzer... that device and oscilloscope are actually two different things. Analyzer can cost 5-10 x of an average oscilloscope. I believe there is no need of getting analyzer when all the analysis you will do will be in audio range anyway - soundcard will be just fine.

Members Meatball Fulton Posted June 6, 2008 Members Share Posted June 6, 2008 My Tek 561A scope. Price brand new was $530 in 1969 , I bought mine used about 20 years ago for $20. Tops out at 10MHz, good enough for audio tasks. All tube, too Link to comment Share on other sites More sharing options...
Members kpatz Posted June 6, 2008 Members Share Posted June 6, 2008 I've hooked my scope up to my synths just for the fun of it once or twice. I just took apart a 1/4" stereo plug, attached the scope probes to the connectors, and plugged it into my mixer's headphone jack (quickest way to hook it up temporarily). But a cable with a 1/4" plug (or RCA plug, if that's what you need) on one end and a BNC on the other would work as well. Didn't some modular synths offer a scope module as an option?

Members Qwave Posted June 6, 2008 Members Share Posted June 6, 2008 Qwave wins the prize. I used to connect an oscilloscope sometimes to our school's EMS Synthi AKS when I was at school in the early eighties. The EMS VCS3 and A is by the way an ideal way to learn analogue synthesis.

Members KingVidiot Posted June 6, 2008 Author Members Share Posted June 6, 2008 Reading oscilloscope manual prior to operation would be a good idea. Your scope will live longer and you might actually get something on the screen. :lol: Point taken, but I received no manual, and an exhaustive search for the user manual for my make and model came up with a service manual which does me no good. On top of that, the manual would explain nothing about how to use it for audio signals. I know because I looked at other similar manuals online. How did you hook your synth up in your other post? What settings did you use? Any help will be useful. I know nothing about o-scopes. I haven't used one since physics lab about 15 years ago.

Members Don Solaris Posted June 6, 2008 Members Share Posted June 6, 2008 What settings did you use? 500mV / 10ms / ac coupling / up slope / trig ch1 / mode x Link to comment Share on other sites More sharing options...
Members KingVidiot Posted June 6, 2008 Author Members Share Posted June 6, 2008 Cool, thanks for the settings and the link. Link to comment Share on other sites More sharing options...
