Possible to sidechain (pumping bass) using the tempo as source?

I’ve got a patch in which I would love to set up a sidechained compressor to pump the bass along with the kick (doing a 4-on-the-foor). I know exactly how to accomplish it with traditional routing of the kick to an unused input, but this would be extremely inconvenient in a touring live environment, and also more prone to failure for no reason. If there was a way to simply use the “metronome” as if it were the kick, that would be perfect. Thanks in advance for any insight here.

Hi,

The workaround you can use is to use the Foog filter to generate a constant sound. Then feed that sound into the synth with the arpeggiator enabled and set to only repeat the root. You can then set the arpeggiator rate as synced to the metronome in 1/4 or 1/8 or … Lastly, use the output of the synth as side chain input in your compressor. Done!

You need to play with the oscillators to adjust the pitch and set the decay to get a pulsing sound.

Feel free to use my quick-and-dirty preset as a starting point:

Thanks for this reply. I’m sure this will get me on the right track. I’m completely unfamiliar with the Foog. I didn’t take it to be a sound source. Isn’t it just a filter for the sound coming in?

it will self-oscillate at a certain point, it’s how the ‘synth’ presets that play backing drone tones are made

The Foog block is a filter effect, based on the Moogerfooger MF-101 Low Pass Filter. I think what @NeuralDave is suggesting is that you may be able to generate a oscillating tone from it at extreme settings, especially by turning the Resonance up.

Feeding that into the synth block will activate its VCA (in other words turn on the synth block), so then you can get an arpeggiated kick-ish sound out of it without relying on the guitar signal.

EDIT: Dang it @xush you beat me to it.

Indeed, it is based on a Moog Moogerfooger MF-101 which is an analog pedal that starts to self-oscillate when the resonance is set high enough.

All we need is ‘some’ sound to trigger the arpeggiator of the Synth, which in turn can generate a ‘pulse’, that you can than use as a side-chain source.

EDIT: Dang it @DiffractionCircuit you beat me to it.

If you’re routing the metronome sound to a specific output, an alternative solution might be to patch this output to a free input on the QC. You can then use this input as side-chaining source.

But that would make you dependent on your actual metronome settings and usage which seems less practical to me…

If you mean the click track from playback, this just isn’t a possibility. It would be unreasonable to involve others in this on a daily basis. This needs to be an entirely self-contained process, so I’ll be using the solution proposed in the earlier replies. Thanks though.

No, i meant to use the sound of the QC metronome itself. You can route this to say ‘Send 1’ in the Tempo screen. Then patch it trough to say ‘Return 1’ and use this as side-chain source.

No dependency on others.., you just need to set your metronome settings in a specific way and sacrefice a send/return loop for this to work consistently.

Either way, good luck!

Wow. This is the kinda thing I needed to hear. I honestly didn’t even assume there was a metronome on-board. I suppose I should have read the manual. I will definitely give this a try. Thanks!

This worked perfectly. Thanks again for this info. Will be thinking of plenty of uses for it!
