I added this as a new idea on YamahaSynth.ideascale.com and thought it would be good to share here as well.
Basically I would like to see in a future OS update, a new LFO Waveform setting/option
This would be especially useful to synthesize a more realistic vibrato of using a whammy bar on an Electric Guitar, whereby the pitch vibrato goes down from the main notes' default pitch. Basically the polar opposite of the Triangle+ option.

Hi, the Triangle- makes sense to me. However until it comes - if it comes at some point - you might try to put a user LFO together which I think could mimic this relatively closely. Did not try it, but maybe it is worth a try... If you look in the Reference Manual at "Edit User LFO", the waveform they put together as an example looks pretty sophisticated...
UPDATE: I actually was able to try it now, seems to work fine for me...
