E-PRO Spirit Font

Warning, this post is about as geeky as it gets.
Background:
Pictured is the E-PRO Spirit. This image was pulled by nick kent who mentioned the following from Peter Forrest's, A-Z of Analogue Synthesis (BTW, these books are must haves for synth enthusiasts. If you want a copy, drop Peter a line): "From picture linked below and the Peter Forrest book text it looks like there is a HP and LP filter in the E-Pro Spirit, though it also looks like they ran out of room to mark the HPF clearly. The abbreviation up top isn't clear or is just too clever. VCI-PF (?)"

Geeky:
Take a look at what looks like the VCI-PF he mentions. Apparently that is actually VCHPF, as in highpass filter. The font they used is called STOP, and the H and P share edges. Just thought that was interesting. Told you this post would be about as geeky as it gets. The font tip came from Chris Strellis on AH.
