I think I figured out what is going on with the pitch block arpeggiator.
FracTool shows the steps in this order: Step 1, 10, 11, 12, 13, 14, 15, 16, 2, 3, 4, 5, 6, 7, 8, 9. When it converts the block it coverts step 1 like it should be, but it converts the values for step 10 as if it were step 2, step 11 as if it were step 3, (and so on) step 12 as step 4, step 13 as step 5, step 14 as step 6, step 15 as step 7, step 16 as step 8.
The conversion comes out as:
Step 1= 3
Step 2 = 24 (when it should have been 0)
Step 3 = 24 (when it should have been 3)
Step 4 = 24 (when it should have been 4)
Step 5 = 24 (when it should have been 5)
Step 6 = 24 (when it should have been 4)
Step 7 = 24 (when it should have been 0)
Step 8 = 24 (when it should have been 0)
etc.
Here is a screen shot of the pitch block arpeggiator section one of Simeon synth presets I converted.
I've already corrected the few presets I needed to by hand so I am good. I just thought this info might help you.
