Fixed Filter Bank

I’ve been meaning to make a fixed filter bank in Reaktor ever since I saw a few videos on Youtube of what they could do. They’re a blast for messing with filtered white noise, especially with some modulation and delay effects later in the chain, but they can also add some real character and dimension to instrumental sounds, bringing out tones that a plain old single band filter can’t match.

In this next one the filter bank action starts at around 2:20 –

My version adds one refinement – you can sweep the overall range of the filter up and down to better match your source material and project. Taking a look inside, you can see that there are only two filter modules, but they’re polyphonic, with each voice accounting for one filter band. This makes a neater structure, and one that’s easier to modify.

Front panel controls are tool-tipped and should be self explanatory.

It’s free, and you can get it here:

By the way, please use a real email address not “mrstinky@qwertyuiop.com” because this and Ghost Shift are going to receive updates and I want to notify users when that happens. Apologies to mrstinky if that is in fact a real address.

Ghost Shift 1.1 with Konkreet Performer mappings

Leave a reply

When I released Ghost Shift I didn’t have live control in mind other than mapping a MIDI fader to the mix control. However, the recent update of Konkreet Performer got me thinking, and I realized there was an easy way to map Performer parameters to the individual delay taps in Ghost Shift. Here’s how that turned out:

Here’s how it works: you set your number of delay taps – I find three works well – in the Ghost Shift instrument properties. The node visualizer instrument is voice-slaved to Ghost Shift so its number of nodes / voices should auto adjust. If it doesn’t, turn Reaktor’s audio engine off and on again.

Make sure Reaktor is set up to receive OSC from Konkreet Performer on your iPad. Here are the setting screens inside Performer, showing which parameters and settings I’ve used:

Notice that every node parameter is active, from angle and length to X and Y. We’re going whole hawg here, using every part but the oink. Also activate the ribbon, which controls the mix of dry and wet signal.

So how does one obtain this marvelous and endlessly entertaining Ghost Shift device? Click here:

Ghost Shift: Multitap Filtered Delay Effect for Reaktor

Leave a reply

Heeeeere’s Ghost Shift!

Ghost Shift is a delay effect based on an earlier version of mine called Pumpkin. I’ve reskinned it, added functionality and fine tuned the filter and feedback parameters for easier sound tweaking.

The major thing you have to know about Ghost Shift is that each delay line works as a separate voice in Reaktor. Adding more voices in the instrument parameters…

…is gonna give you more delay taps, and magically, the number of controls in the delay time, pan etc. graphs will auto-adjust to the number of voices / delay taps.

Each voice can have its own delay time as a multiple of 16th notes, separate pan, feedback and filter settings. I’ve included just a handful of presets because the settings are going to be highly dependent on the material you’re running through the instrument. Really sparse input with lots of space can have more delay lines and more filter feedback. A more full audio track, like a drum kit, will benefit from no more than three delay taps, widely panned, and not much feedback. Let experience and experiment be your guide.

Everything’s tool tipped and self explanatory. A saturator can boost the signal as well as keep it from clipping unpleasantly at the output. The one control you will want to have mapped to a controller or mod wheel is the Mixer, so you can crossfade between dry and wet signal. You’ll hear that happening in this Soundcloud demo:
