No, you can definitely get the slide even if you manually draw notes in piano roll, without ever playing them manually, as long as the rules of triggering the slide are obeyed.
EvilDragon said: Sustain pedal must be pressed for slides to work, and notes need to overlap. This is explained in the manual for MM Bass.
Very odd. I clicked "Yes" to indicate that your previous comment answered my question, and now the comment is gone.
On a side note, I posted that screenshot of the manual's illustration for keyswitches because it seems to have a typo. "C string (C0)" and "B string (B0)" should be E string and G string, respectively. Or am I missing something?
Appears the "Accepted Answer" comment gets moved up the food chain and listed as "Best Answer" directly under your original post...an unexpected new feature!!!
Quick and definitive. I think I like that. Thanks for clarifying.
