yup yup... the internet says:
"An article by Don Lancaster in the February 1971 issue of Popular
Electronics magazine described the "Psych-Tone", based on the same concepts,
but not as complex as the original Muse. This article includes a side bar
with a picture of the Triadex Muse and the text:

"A recently introduced unit which is quite similar to the Psych-Tone is the
Muse. ... With 14 trillion note combinations, the Muse has four switches for
volume, tempo, pitch, and fine pitch and eight slide switches. Four of the
latter vary the interval and thus determine the notes, while the other four
control the theme and varaiations of the melody."

"SWTPC (South-West Technical Products Corporation) produced a kit of parts
for the Psych-Tone. "
