Suboscillator question

#1

So tonight I started my first patch.

I created a standard saw osc with adsr patch - all is well.
Now I liked to add a sub osc to give it more oomph down low, so I added and mixed a square wave at one octave below, with its own gain control. (As I thought that's basically what a sub osc normally is?)

But when I fade in the sub osc, it doesn't sound like any low end is added - I mean, something has changed in the sound, but it sure isn't deep oomph :slight_smile:

In cpwitz's Junebug Juno106 patch the subosc works pretty nice, but the patch is so complicated I haven't figured out yet what's happening.
I see he's mixing in a square wave one octave lower, but after that some sort of filter is applied that I haven't figured out yet - lots of incoming parameters from other operations.

How do I implement a nice sounding subosc for more rounded oomph in the low end?

i would try with a sine oscillator first.

..or triangle. If you're still having problems, post your patch.

I know this is not "standard", but you could also add a tiny bit of saturation to your sub osc? I think that could live it up a bit.

#5

The class a distortion object (I'm travelling ATM, so I can't tell you the exact name) is quite nice.... smooth and beefy, not grating.

Well, a Sub Osc is not a second oscillator, is a sub division of the actual main oscillator (like in the Juno-106, SH-101, etc). If you add a second oscillator one octave below will give you a different sound because both oscillators aren't in phase...
You may try a counter to or some frequency divider to get a propper sub-osc.

hmm try my divider and stitcher objects, maybe they work out for you?

#8

I've been asking this myself, aren't oscillators on the axoloti always initially in phase, as they are digital?

#9

No, just try it, patch 2 oscillators with the same frequency to a mixer, and add an oscilloscope, you will see the aren´t in phase...
