Now that I have had a chance to study the 250e more closely, I realized Don used the term 
"Arbitrary Fuction Generator" in a romantic or philosophical sense, rather than in a strict 
technical sense. There is nothing wrong with that, I am sure if you buy a guitar stomp box 
called an "X-Ray Machine", you do not actually expect to use it for medical diagnostics.

The 250e bears little resemblace to what engineers consider an Arbitrary Function Generator. 
It IS an extemely full featured sequencer.

On the technical side, it lacks a remote computer programming interface and supports only 
straight line segments from flat to various slopes. I am sure, like all Don's products, thats it 
is a lot of fun to use and produces musical results. But since it is not technically anl Arbitrary 
Function Generator, there is little sense in comparing it to the Envelooper.

I am investigating the use of in-circuit programmable Flash memory in addition to, or 
possible replacing the PROM. This will allow reprogramming the data contents through a 
front panel interface with JTAG cable to a computer.

In this specific case, God bless progress and the rapidly falling memory prices.
