Gated Fm Flanger Lead

Updated: Nov 10, 2020

This week we go with another tutorial, and this time I chose to show you “Gated Fm Flanger Leads”. Flanger leads have been used in psytrance a lot back in 2002-2006 and now they are back in use.

Plugins needed: – Xfer SerumSoundtoys EchoboyFabFilter Pro-RFabFilter Pro VolcanoFabFilter Pro-C2 – Flanger (any with manual option)

First, open serum, and do few setups – Connect LFO1 to OSC A Volume, and make the curve as you like – Turn on the filer, and choose Band 12, and put Drive to 45% – Turn on Sub OSC and put the level to zero, octave -1 – In OSC A , from modulation menu, chose FM from SUB and put around 37%

Now, we need to connect Chaos1 and Chaos2 LFOs to modulate Cutoff For those who don’t know about Chaos LFOs, these are the “random” LFOs that are used a lot in psytrance. You can control those LFOs from the “Global” tab in Serum. To set them up, go to global and chack all 3 checkboxes on Chaos 1, and rate put to 1/16 note. Chaos 2, check the S&H checkbox and rate put to 2.5khz


Now we are going to move to the Matrix section, where all the magic happens. A matrix is a place where you can see all the modulations and where you can control them. As we already connected manually LFO1 to OSC A Volume, it will automatically appear in the Matrix tab. But we can also add some modulations from the Matrix tab. So go to Matrix and in the second slot add the Chaos 1 as Source and Cuttof as a destination. The amount I used is 37, but you can play around and find a nice position for yourself. In the 3rd Matrix slot, chose Chaos 2 as a source and OSC A – A Vol and amount set to 30. What this will do? As we already created a gate, with this setup we will play a bit with a sustain of the OSC A volume. This kind of trick is used a lot in faster Psytrance productions such as Ajja, Outsiders, Tristan ….


Now we move to processing of the lead. We are going to add Flanger, Delay, Reverb, and compressor.

First, add a flanger (with manual mode) and draw automatization of flanger as you want. I drew from zero point to maximum in 16 Bars
