I am an avid user of a drum-synth plug-in called Microtonic, supplied by a Swedish outfit called SonicCharge. (And recently, I got their Permut8, an interesting program that simulates a delay line.) Which is to say I am on the company's mailing list and received notice today of another program they just developed called Echobode - http://soniccharge.com/echobode . It's described thusly: "Echobode is a delay effect with a frequency shifter placed inside the feedback loop. The frequency shifter algorithm is inspired by the classic Bode Frequency Shifter (named after its inventor Harald Bode." This code is available only for use with Reason, however; it's not a universal VST/AU plug-in.

So, based on this description, I thought I'd try my hand at making my own such frequency shifted delay, and that is the patch you find here. I have no idea if it resembles what Sonic Charge has developed, in concept or specific layout. But it makes some far out, groovy sounds, so I am sharing it. 

Until now, I'd never heard of Herr Bode, but he seems to have been quite an interesting person, born in Germany in 1909 (died 1987, in U.S.A.) and inventing many interesting pieces of electronic equipment for making music:

Instructions: Be careful with the Freq. Shifter's Wet/Dry Mix control; too Dry and feedback gets out of control. But play around with the "delay time" settings on SDelay 2 (there's only one delay, actually); sub-1/8th settings make for some very out sounds. Also, fool with the Rate setting on Freq. Shifter 2 (again, there's only one of these)  and you'll find some interesting effects. You'll notice I am using only one half of the delay contraption; one could use both sides and find more interesting sounds, I have found, but I am posting only the basic idea here.

Enjoy!
