I love the 4ms Tapographic Delay. It can take the simplest of sounds and make it richer and wider. A common use for me is to have the stereo panning set to Alternating, and a programmed tapo of 6 or so delay lines with different filter resonances. Modulation is set to about 85% to give a bit of swim. With the dry/wet mix at 50/50, I use the feedback control to dial the intensity up and down.
It’s extremely good at building up a simple drone into a lush wall of sound. It’s distinctly digital sounding, but the filters add a nice colour to the sound.
I run three signal chains in my euro, the 4ms is at the end of one of those chains, used to create lush pads. There’s a Belgrad inserted in the path just prior, which allows me to add interesting (not too harsh) timbral modulations to the sound. The 4ms picks that up and lushifies it.
