Q.  I don't know much about oscilloscope vst's but is it possible to examine the filters outputs using one?  Also which is the best freeware vst oscilloscope?  Or do they only work with waveforms.  I don't see how to change the difference?

HI methodman3000,

There are a lot of freeware vst oscilloscopes out there a good place to start is this page, though there are many many more http://blog.wavosaur.com/best-free-vst-plugins-for-analyzing-audio/.

You say you want to analyse the filters output but you don't say why, i guess you want to see how the filter effects the harmonic content that passes through it?

Oscilloscopes (time domain), generally, look at the wave shape. When you filter a wave, say a sawtooth you can turn it into a sine wave and all sorts of misshaped waves, the important point here is how it effects the harmonics / timbre and to properly understand that you need a spectrum analyser (frequency domain).

I used the one that comes with Soundforge for years for spectrum analysis and have recently bought an oscilloscope, though i used the very useful https://www.zeitnitz.eu/scope_en for a long time. This one takes a bit of routing from your DAW through a virtual cable and then you have to monitor this by turning on,, listen to cable output, in windows sound menu. Otherwise you wont hear an output. Which was okay for me as im a bit masochistic and clearly a VST or DAW based oscilloscope / spectrum analyser is a much more convenient route.

Also very good is the Yoshimasa Realtime Analyser , which is a complete package of analysis tools that was mostly aimed at room testing / setup, i believe for Hi Fi enthusiasts.  It is not free and cost around $98 . http://www.ymec.com/products/dssf3e/index.htm i think that is a very fair price for what it does though. But as above it takes a little getting used to and the routing is fairly straight forward compared to some. I use this all the time.

They can all take a bit of getting used to and can be fascinating and revealing instruments. Hope this helps a little

Is a virtual cable like midi ox relevant today?  It seems as if some of the older sequencers like Dr T's Keyboard controlled   Level 2 sequencer actually had more flexible ways of dealing with midi than the pc and Mac  generations of programs.  Other than VST' Are todays sequencers really that more flexible than the 90's ones were.  It seems as if some of the midi flexibility has disappeared on many major sequencers.

What are some uses of virtual midi cables?

Hi the cable i was referring to is not a midi cable but an audio cable. This is the one i use http://vb-audio.pagesperso-orange.fr/Cable/.

I guess I am not familiar enough with the purpose of different kinds of thngs.  You were rigfht I wanted to look at the frequency spectrum that was being cut mainly for Omnisphere but the Matrix 12 and the SynthMaster seem to have some interesting filters too.  As far as a virtual audio cable what are some examples of what I can do with it.  I mostly use midi and then bounce it down as a wave or mp3.  What would an audio cable alter?  I also use Band and a box to start

Hi, you route audio virtually from piece of software to another. I suggested this as an option rather than just using VST plugins like the ones i mentioned above as there are some really nice software oscilloscopes and spectrum analysers.

You do not need to use the virtual cable but if you want to then watch this video https://www.youtube.com/watch?v=oEWS2kxzqCQ.

If all this is alien then just try the VST plugins.

Hope you find what you're looking for
