I agree. Sawtooth decreases left-to-right and Ramp is opposite.
“Back in the 70’s” we definitely distinguished between Ramp and Sawtooth. Some like to say “they’re the same thing because they have identical harmonic spectra,” but that’s not the point. That presumes you’re using a sawtooth as an audio wave which is a strange thing to presume, and in any other context, the distinction is important.
In recent years, the term “ramp” seems to just be dropped and both ascending & descending waveforms are called “saw,” but personally I think the old distinction was more helpful.

Hi, all!
If I may be so bold as to step in where I'm not wanted: ;->
∗ - As with most of the Western languages, we read from left to right
∗ - Therefore, if we consider that "standard", a RAMP wave would increase from left to right
∗ - A SAWTOOTH would be the opposite, decreasing from left to right
∗ - (Even though actual sawteeth rely on the ramp of the teeth to cut on the push stroke for Western saws [as opposed to say, a dozuki or ryoba], if you turn it the right way... ;-) )
∗ - There is a tremendous probability that I may be completely F.O.S. This, however, is how I've discerned a SAW from a RAMP wave.
To use that tired old saw ;->, YMMV.
Guess I need to find something to do...

Yes, that´s a question to ask Oakley synths who uses the term "ramp" on their LFO ;) --- On Sat, 2/5/11, Paul Schreiber <synth1@...> wrote:
What is a ramp wave if not a saw?
