My bad.  Upon further inspection, both of mine do the same thing.  So
I changed my LED indicator to saw to remind me of that fact.  I told
you I could be missing something :)

While I'm typing about the 320, how much of difference in frequency
range have you noticed between 320's??  For example, one of mine,
without any CV, has a top rate of 200 Hz, the other 30 Hz.  Is this
due to parts tolerances??  I can't measure their lowest rates with
the frequency counter I have, but if anyone is that curious I could
try using a stopwatch.

Apparently, it also gives you in-between amplitude and offset.

I rarely ever use pulse, except as an occasional clock, and the fixed
triangle is pretty much the same as any other triangle, but the
variable sine shape is awesome!! I built a couple of 10Vpp to 0-5V
converters so I could use the 320 outputs with pedal inputs.

Well, unless I'm missing something again, the 320 does produce a
constant 10Vpp saw.

I was surprised to hear that Oakley was back in business.  Imho, the
issue with third party PCB's is the difficulty in getting panels and
mounting brackets, and  the issue with Synthesis Technology diy is
the cost of the parts -- where the just pcb, panel, bracket and
billet parts, not including the knobs, jacks, and all the more common
parts, can cost more than the entire kit did.
