1 QUICK START
Once you have installed USTA and powered up your
system, you will see a fast boot screen with the Frap Tools
logo on the OLED Display (C.5), then a screen with var-
ious details concerning the project you are about to cre-
ate. Track 1 (B.11) and its CV A (B.6) are already selected
and ready to be edited.
Start rotating the 16 encoders (A.1) and you will see that
the LEDs surrounding them (A.2) are progressively light-
ing up, and at the same time a changing note name ap-
pears in the lower-left corner of the Display, indicating
the pitch of the selected stage of the sequence. This is the
content of the sequence, which will be outputted by the
CV A jack port of the first track (E.1).
