How to mix oscillators

[muleskinner]

Hi,

I know there's probably several answers to this. I'm simply trying to mix the sounds of two oscillators and have the resulting 'mix' routed through an XFM filter.

Currently I have osc 1 in channel 1, osc 2 in channel 2, and a 'mix' module in channel 1 taking input from channel 1 and sidechain input from channel 2.

This works fine, only that osc 2 is still routed to the output when I want it muted.

Is there any more elegant way to do this other than muting the output of channel 2?

cheers

There are many ways to accomplish this...

You can of course mute channel 2 (little grey/red square below the grid and above pan, next to "main")...

A nifty trick is to use a plain Modulation Mixer (i.e. MMix1) to control Osc1 Volume and Osc 2 Volume in opposite directions (Osc1: 100/-100, Osc2: 0/+100). Then, i.e. the "Const" knob in ModMixer1 crossfades between the two, but you can also use envelopes and stuff inside the ModMixer. Here's a patch that does this:

Or simply put OSC 2 in channel 1 above OSC 1 - both oscillators are mixed together, and you don't need a mixer module or another channel...

Thanks Urs, and thanks for that too - the above doesn't quite work for what I want as I want to be able to control or modulate the balance between 1 and 2 but it's still a good tip!

Sorry for the ignorance, but what do I do with the text that comes up from the above url Urs left?

I tried copying to a text editor and saving with an h2p extension. It showed up in the preset list but didn't change any parameters.

Thanks

Hmmm... that should work.... maybe right-click and save as?

Thanks Urs. That did it.

You could e.g. use a Mixer module, but you don't really need to waste a second lane in the grid - you can simply modulate volumes in opposite directions from the same source. Here's an experiment to make that clear:

Start from a clean slate and put two oscillators in lane 1. Set OSC1 volume to 100 (12 o'clock) and OSC2 volume to 0. Modulate OSC1 volume with e.g. ModWheel, amount = -100. Modulate OSC2 volume with ModWheel, amount = (+)100. Basta.

EDIT: Ah, I see Urs explained this already!
