I've been so busy getting everything ready for NAMM that I forgot to prepare an elaborate April Fools gimmick. Please pretend I've done something very funny and make sure to have a good laugh about it. Thank you for your indulgence.
Perhaps you could reverse the clock phasing in the glass butterfly like behringer have?

"The Moog MF-106TC Analog Time Compressor, right, was announced April 1st, 2009, but has never been released. According to the company, the effect was the result of a happy accident:
“We accidentally reversed the clock phasing in the time generation on our MF-104Z Analog Delay, and discovered that it can actually work in reverse, compressing the time stream instead of expanding it. Much to our amazement and delight we began hearing sounds up to 1000 milliseconds before we played them,” said Amos Gaynes, Moog Temporal Engineer.
Gaynes said that the Analog Time Compressor circuit on the MF-106TC can eliminate digital latency in real time, or sound like you’re playing faster than you really are. The Analog Time Compressor’s unique Slap-Forward delay effect sounds even better than Slap-Back, according to Gaynes.
“The MF-106TC has hundreds of unique applications,” said Moog Marketing Manager Chris Stack. “Used on the Pitch Preview output of our new Etherwave Plus Theremin, you not only hear your note before the audience does; you actually hear it before you play it.”"
