WASP

Lookie lookie what I found in the TESS database: This seems to line up with the earlier leak of Behringer synths. If the leak is to believed here is the feature list: It looks like they're trademarking the logo from the original Wasp Deluxe:

...meow sound (in an underwater 'Jacques Cousteau documentary' kind of way). Best meow I ever pulled off was on my old EDP Wasp. Worst cat meow sound pre-set was on the DX21. A pitiful attempt

...in the filter. D-50's filter was unique but resonance wasn't its strong suit. I'm not familiar with the Wasp but it sounds like something that could do it well. DX21... yeah, 4 op cheap DX7 wannabe with no filter ain't gonna meow for beans.
