I saw this in a preset once but I simply cannot figure out how to do it.

The scenario is oscillator in lanes 1 and 3, both feeding a filter in lane 2

Oh, and without using a mixer module.

Right click the filter module, sidechain. Oh, and you can do this only with XMF, not VCF.

Just making sure: To simply send 2 oscillators through 1 filter, stack everything up in 1 lane only. Oscillators let signals through. It's all in the manual.

Ah that's it, I was trying to do it with a normal VCF, thanks

Sure, but I wanted to know how it was done and also think it'll come in handy later on. I actually have the manual printed and bound and didn't fathom Evildragons solution above!

That'll sure come in handy, thanks

I thought the OP wanted to mix the audio of both oscillators through a single filter on a different lane, so this won't work, right? As far as I know, the side chain input of an XMF doesn't route the audio from an oscillator through the filter. It allows the side chain signal to modulate the filter.

Yes, of course. If I wanted to run two oscillators through a single filter, I'd do something like this too. But the OP had an oscillator on lane 1 and one on lane 3 and wanted to run them both into a filter on lane 2. EvilDragon suggested using an XMF on lane 2 because it has the extra side chain input, but I was saying that I didn't think this would work because the XMF side chain input is used as a filter modulation source and doesn't pass the audio from the side chain through the filter.

OK, now I get it (duh). Needs a mixer.

Nope, Scoplunk and ED were right, you can use input and sidechain together with an XMF module

I see what's happening now. You're being fooled by the fact that you've got all the lanes still going to the output, so you're still hearing both oscillators.

You need to mute lanes 1 and 3 to just hear the output of the filter (the mute is the little square button to the immediate right of the four boxes that say "main" right below the graph. They turn red when muted.). If you mute those and only listen to lane 2, you'll hear just the output of the filter. Make the two oscillators sound different by assigning different waves or tuning one of them down a few octaves. Assuming that you assigned Input 1 and SideChain 3 to the XMF, you'll hear that only the oscillator from lane 1 is still present in the signal path and is being affected by the filter. When you turn the Filter/FM knob to the right, though, you'll hear the filter being modulated by the oscillator in lane 3. Leave the knob turned fully right and experiment with changing the pitch of the lane 3 oscillator and you'll get an idea of what kinds of things you can do with this arrangement. It's a great effect and you'll probably wind up using it quite a bit, but it isn't the same as a simple mix of two oscillators being filtered by the same filter module like Howard described above.

The conversation moved on beyond that - or so I thought (Scoplunk wrote: "EvilDragon suggested using an XMF on lane 2 because it has the extra side chain input, but I was saying that I didn't think this would work because the XMF side chain input is used as a filter modulation source and doesn't pass the audio from the side chain through the filter.")

Yeah, you might be right, Howard. I'm not exactly sure what we're trying to do anymore! But I guess tehlord has a few things he can try now.

Put simply I'd seen this routing done, couldn't figure out how to do it from the manual and just wanted to know!

EvilDragon · Post by **EvilDragon** » Wed Jun 17, 2015 4:31 pm

So, it was not about the resulting sound, just about the actual sidechaining feature.
