138 Degen Regen BPM
Long delay allowing loop instability
PAUs:
4 each
Degen Regen BPM starts as a simple mono delay line with feedback. However with the Fdbk Gain and
Dist Drive parameters, the algorithm can be pushed hard into instability. When Degen Regen BPM is
unstable, your sound gets a little louder on each pass through the delay line. Eventually the sound will hit
digital clipping when the effects processor runs out of headroom bits. To keep this all under control, a soft-
knee compressor has been included inside the delay line loop. With the compressor properly set, the
sound never reaches digital clipping, but it does become more and more distorted as it gets pushed harder
and harder into the compressor. To make things really nasty, there’s also a distortion in the delay path.
(The distortion parameters are on the PARAM4 page with the compressor parameters.)
Degen Regen BPM uses all 4 PAUs available for insert effects. With the resources of all 4 PAUs available,
Degen Regen BPM lets you set the longest mono delay line available in KDFX which is just over 20
seconds. If you want a long delay, this is the algorithm to do it. (You don’t have to over-drive the feedback
or use the distortion.)
The delay has two output taps in addition to the feedback tap. Each tap may be moved along the delay line
using an LFO (internal to the effects processor). The output taps have separate controls for level and
panning (in the stereo configurations).
Throw a few filters into the delay line loop, and you get a pretty versatile delay line. The available filters
are highpass (LF Damping), lowpass (HF Damping), bass shelf, treble shelf, and two parametric EQs
(Mid1, Mid2).
For details about the compressor see the documentation for SoftKneeCompress. For the distortion see the
documentation for Mono Distortion.
