In this article, I will do a small write-up about a technique I sometimes use to drive a filter into a different analogue type of filter effect. While normally you could use the Thor Filter with Self Oscillation. This is a nice touch since you are adding a sine wave on top of the waveform itself. This method is ideal for making your filter scream analogue (since in the analogue world this technique is often applied because they respond to frequencies). A lot of analogue filters also love the idea of using control voltage inputs where these inputs are controlled by oscillators (which are often free running or used in combination with a sequencer). These type of setups make the filter rather aggressive, yet unstable at the same time (something that a digital filter does not do since they often sound very clean). So with that said, I will create a setup and show you a method to put dust on a filter.
Not so long ago I saw a new shop item flying by called the ZPlane Morphing filter from Lab One Recordings. While the ZPlane Morphing filter is inspired by the Red Queen Equalizer it has the added touch to it to morph two filters using a morph rotary. In theory, this is similar to using 2 filters in parallel and use a balance knob in between to balance two different filters. While I have made setups like these many times before using the Mixer 6:2 or Mixer 14:2 there is one device (which is a free rack extension) that can do something similar in this context.
Because I am about to touch the rack extension realm, and the earliest version I have installed at this point in time is Reason 9.5, I will add that all the example files I will be presenting are made with Reason 9.5. While they should work with Reason 6.5 and above, I hereby cannot fact check if this will work properly in older versions of Reason (just adding this as a disclaimer).
