Title: Show input signal of matrix on oscilloscope?
Post by: mkoch on March 28, 2023, 11:24:42 pm

Hello,

is it somehow possible to show one of the 16 matrix input signals on an oscilloscope?

I sometimes like to visualize a modulation source. To quickly do that, I use the source to amplitude modulate a high pitched signal, then you can see the modulator as the signal envelope on a scope (running on the PC through an audio interface).

Here's an example of that (https://gearspace.com/board/electronic-music-instruments-and-electronic-music-production/1057788-arturia-matrixbrute-88.html#post13534865)

There's also the 12 first colums of the matrix output on the mini-jacks on the back if you have a scope to connect.

But you can only see the positive part of the signal, correct?
If a schematic diagram were available, I would really like to wire some internal signals to an oscilloscope.

If you run the mod amount of the VCA at 50%, then you'll see bipolar modulation as well. Another trick is to use the mod wheel to offset the modulation (just add it to the column you're monitoring). For wiring up a scope, you can use the matrix outputs if you just want to visualize a modulator(?)
