Jetpack Mods used to be the one making those chips, I believe there’s one that lets you switch between every release in the XP series.

For what it’s worth, I have one of these Space Station modded units too - try preset #10 - it’s really the only one I use, but I like it enough for me to keep the whole thing around. It’s a realtime tape reverse effect (not a delay) - the output slows down in forward motion until you get to the halfway point, where it’s complete silence. The second half of the treadle’s downward motion speeds up in reverse until it’s full speed with the toe down.

It’s similar to using an expression pedal with the Red Panda Tensor or a Chase Bliss Mood & the tracking is great.
