Eeek - I didn't mean for that lecture to come off as anti-PPG. I have an
original Microwave and I love it - if I were to start selling off my other
hardware, it would be the last thing to go. (I also have a Prophet VS
rack, so I am a fan of the wavetable thing.) I would certainly not kick a
Wave 2.3 out of bed. ;)

Did I say they were? Shoot, didn't mean to if I did. I might have been
getting it mixed up with the Prophet VS - I recall the waves from that
came from a variety of sources.
As the course progressed I got more ond more busy with non-course related
things (I graduated two PhD students this semester and got to "hood" them
at graduation last Saturday! Yay!) so the lectures get less and less
coherent.

I have to confess I was just quoting what I'd heard from various sources.
I've never actually heard or seen any of the early PPG digitals in person.

Again, was just quoting what I'd heard. ;)

Ooops - darn. I was in a big hurry putting that lecture together.

That certainly is true - but when the DX7 came out at its price point, it
must have taken a bite into PPG, no?

Oh, the first point there I didn't know - I thought the wavetables in the
2.3 were 12 bit.

Did you know that the Monowave filter was part of one of my homework
problems? Check out HW #6... ;)
