Hello,  
I would like to know how to side chain in tidal.  
For instace, I would like a sidechain between d1 and d2.  
I’m sure is possible to setup in supercollider, but I don’t understand the language enough to try.  
Do you have any idea?

Thank you very much

I just saw this on twitter someone had a similar question about side chain compression and tagged @tidalcycles

“Yes, check the ‘hacks’ folder in superdirt to have one orbit sidechaining the other“

Not sure if this answers tour question but I wanted to relay in case it does.

Yes here’s the file in question [https://github.com/musikinformatik/SuperDirt/blob/develop/hacks/filtering-dirt-output.scd](https://github.com/musikinformatik/SuperDirt/blob/develop/hacks/filtering-dirt-output.scd)

thank you guys for your answers, I tried and it works like a charm 🙂

here is the code to create a sidechain between d1 and d2

(  
~bus = Bus.audio(s, numChannels:2); // First, create a bus  
~dirt.orbits[0].outBus = ~bus; // Then, link a track to this bus  
(  
Ndef(\x, {  
var control = InBus.ar(~dirt.orbits[1].dryBus, 2).sum;  
var dirt = InBus.ar(~bus, 2);  
Compander.ar(dirt, control, thresh:0.001, slopeBelow:1.0, slopeAbove: 0.651, clampTime:0.05, relaxTime:0.1)  
//dirt \* (1 - (Amplitude.kr(control) \> 0.007).poll.lag(0.01));  
}).play;  
)  
)

// clean  
(  
~dirt.orbits[0].outBus = 0;  
~bus.free;  
)
