The Complete Guide to Sidechain Compression in Trance: Beyond the Basic Pump Most trance producers think sidechain compression is just about creating that pumping effect, but there's a whole world of precision and technique that separates amateur tracks from professional releases. Let me show you the exact methods I use to create driving, clean separation without sacrificing energy. Photo by Adrien Delforge on Unsplash Here's something most producers get wrong: they think sidechain compression is always about that obvious pumping effect. But in trance, sometimes we use sidechain to get that bumping effect, and sometimes we don't want to use sidechain at all so everything feels a little bit more driving. The key is understanding when to use each approach and how to execute it with surgical precision. When my kick and bass are playing together, I definitely sidechain the bass with the kick. But here's where it gets interesting - I don't necessarily need to use traditional sidechain compression because in trance, you can use volume shapers like LFO Tool, Kickstart, and Shaper Box to achieve very nice separation with much more control. ⚡ Quick Take Sidechain isn't just for pumping - it's about separation and drive Volume shapers (LFO Tool, Kickstart, Shaper Box) can replace traditional sidechain Choose your approach based on the energy you want to create The Art of Harsh Sidechain When I do use traditional sidechain compression, I go harsh. I'm talking about compressing the bass almost all the way down during the kick hit. This isn't subtle - it's surgical. The goal is to make sure that the first transient of the bass - that crucial first 1/16 note duration - is fully silenced at the start so the transients don't overlap. This technique really helps make the track nice and driving. It's not about creating obvious pumping - it's about creating space for your kick to punch through while maintaining the energy flow of your bassline. From my studio - where the magic happens The first 1/16 note duration must be fully silenced - no exceptions. This is what separates amateur sidechaining from professional results. ⚡ Quick Take Harsh sidechain: compress bass almost 100% during kick hit Silence first 1/16 note duration to prevent transient overlap Focus on driving energy, not obvious pumping My Precise Compressor Settings If I use a compressor, I like to be very precise. Here's my exact approach: I always measure the 1/16 note duration in milliseconds for whatever BPM I'm working at, and use that as my release time. My attack is always super short, as close to zero as possible. Unfortunately, the Ableton compressor will always give you clicks even if you try to make it nicer, so I've had to develop some workarounds. Make sure to use peak detection mode so the compressor responds to peaks rather than RMS/average levels - this gives you much tighter control over transients. Here's a pro tip that most producers miss: I like to use only the high-end click from my kick for the sidechain trigger. So I always have my EQ turned on and high-passed at about 800Hz so I'm only getting the clicks. That makes the sidechain super nice with a very nice curve. When someone asks why I measure everything in milliseconds - via GIPHY For every BPM, I set the release to match the exact 1/16 note duration for that tempo. There is no magic number - I always measure the 1/16 in Ableton and it shows me in the bottom left corner the exact value in milliseconds. This precision is what makes the difference between amateur and professional results. ⚡ Quick Take Release time: exactly 1/16 note duration in milliseconds for your BPM Attack: as close to zero as possible Peak detection mode, not RMS High-pass sidechain signal at 800Hz for clean transients MIDI Trigger Setup for Volume Shapers When I work with LFO Tool, it's good to have a MIDI trigger setup. Here's my exact routing: I have an external instrument inside an instrument rack where there's nothing actually playing, but I'm just sending a signal to LFO Tool. I set it to MIDI trigger mode which is turned on in LFO Tool, and then it reads the MIDI from the top. I use a kick sample in Simpler as the trigger source, then high-pass filter the sidechain input signal at around 800Hz to focus on the transient. The output is set to "sends only" so it doesn't send any audio - it only sends the trigger signal. This setup gives you incredibly precise control over your sidechain timing and allows you to use any MIDI pattern you want, not just the audio from your actual kick drum. ⚡ Quick Take Use external instrument in rack as MIDI trigger for LFO Tool Kick sample in Simpler, high-pass at 800Hz, set to "sends only" Enable MIDI trigger mode in LFO Tool for precise control My Tool Preferences and Why If I need sidechain super fast, I'm using Kickstart. If I need something super precise, I'm using Shaper Box or LFO Tool, but I noticed with Shaper Box my volume just goes down, so LFO Tool and Kickstart are my go-to tools. For LFO Tool, I generally use the preset called "sidechain one" where I take the top right corner square and pull it a little bit to the left so we don't have any clicks. With Kickstart you can still get some clicks which is annoying, especially in breakdowns where every detail matters.

Set up your sidechain compressor with attack at 0ms, release at your calculated 1/16 duration, and use peak detection mode. High-pass your kick trigger at 800Hz and listen to the difference in clarity. 🎓 Take It Further Pro Trance Template by ReOrder The ultimate production toolkit born out of my SOLD OUT Pro Trance Masterclass.
