***MOD IDEA BELOW***
Just in time for Halloween…
This is a set of 5 audio paths going through 4 delay lines, each with a varying level of multi-filter applied. Each delay line is longer than the previous and filtered at a lower frequency than the previous. All 5 audio signals (dry source included) route back to a mixer, which pans the delay lines. The stereo output from the mixer goes to the Ghost Reverb. The end result is a ping-pong effect with longer and darker delays.
PREVIEW – The soundcloud link shows this in use with both a 0-Coast Krell patch and some sounds from my Zoom H5 mic.
– Row 1: Stereo In & Out with a gain control
– Row 2: Gate control (I designed this to use with my Zoom H5 as a source, and the mic picks up room noise), with a Star on the Threshold
– Rows 3 – 5: Mixer
– Right Side: A filter for each of the 5 rows (magenta). The top one is set to no filtering. Each row down has a lower cutoff frequency.
– Left Side: Rows 2 through 5 are the Delay Lines (pink). Each Delay Line connects to the filter on the same row. The Delays are set to max out a 16s, but can be set shorter to save on CPU performance, if needed.
– Top Left: The green Value module is used to control the length of each delay, keeping them all in a fixed ratio. the math is done on Page 2, and there is a Star control for the value. Higher values = longer delays.
– Each row is a Value connected to a Multiplier which connects to the Green Value on Page 1 or the Star page. Each row aligns with the Delay Line rows on Page 1. Adjusting the values in the first column changes the distance of the delay values, which follow the Multiply function.
– Note – The Value on Page 1 connection strength to each Multiply function is 46.45%. Feel free to experiment with settings.
– Ghost Reverb connected to the Mixer Output and the Audio Out on Page 0.
– Adjust the Value as the primary control. Smaller values will get tighter delay line spacing. Longer ones will get wider spacing. As Value goes over 0.8900 and the longest Delay Line will max out at 16s, but the shorter lines will continue to grow longer.
– Adjust the Threshold to filter the noise floor. If you aren’t hearing a signal when the patch is engaged, check this setting to make sure it isn’t too high.
Interesting results can be had be changing the following:
– Panning – 50/50 – 66/34 – 24/76 – 86/14 – 4/96
– Connect the output of each filter to the input of the delay line on the row below. So, Row 1 Filter (far right column) to Row 2 Delay Line input (far left column). Repeat down each row. Row 5 Filter connected back up to the Row 1 Filter input (no Delay line on Row 1). Similarly, you can reverse the connections so the Row 5 Filter connects back up to the Row 4 Delay Line.
I suggest connection strength of -6.66 dB, because what else would one use?
