Hi,

in Pa1X some styles are already programmed with ritardando inside (especially for endings) while as ritardando function it can be assigned to any programmable switch (button or pedal) and using different curves.

It seems to me the most complete implementation available.

I don't think that T2 has ritardando inside any style, anyway I can confirm that pressing twice the ending it will apply.

Hope this help.

Regards.
