Tape delay patch

Another try to get around the memory limitations of the NM to create a usable delay/reverb patch with delay modules. It's is based on a technique I saw some time ago on the list, but I can't remember who made it and when exactly... (does anyone know ?)

It's a few daisy-chain connected delays with the sound inserted and extract interlaced by a crossfader and a s&h, driven by a high frequency oscillator. By using input and output lowpass filters around a few Khz the high hiss caused by the downsampling is cut off.

Set dry/wet level with knob 1, and feedback with knob 2. I think there are some some things that can be improved, but it's quite usable already. Also nice in the CVA to give dry patchs some extra touch.

That would be me! Posted it about a month ago.

I made a little writeup of the technique on my nordmodular web book (www.cim.mcgill.ca/~clark/nordmodularbook/nm_book_toc.html) in the section on reverb and delay effects. I think I can make it much better, as I know how to make an audio-rate quadrature oscillator. But I don't have access to my NM until May, so I can't try it out until then. Will check out your patch Ico, at least look at it, not listen...

Aah, good to know J To make it clear: credits of the technique go to Jim !

I added another one, this is more like a reverb, does a good job with my guitar. If you tweak with some of the parameters you get a feeling of how it reacts. There's a lot of 'wrong' settings too that only give noise. Just try it...
