It would be nice to add legato for midi notes (in the Note list menu)
Don’t know if it’s possible to implement given the fact that Polypulse is based on AMP enveloppe and not “Note Off” midi message.
If you only want specific notes to slide and not all notes set the note type to note slide (retriggers envelope) or slide (does not retrigger envelopes): Note lists - PolyPulse manual
If you want all notes to slide set slide all notes to true: Poly pulse sequencer - PolyPulse manual
The slide time is set with an encoder on the left encoder bank.
Yes but a slide is more like a potamento not a legato.
If legato effect is implied in the slide function then it should be notified clearly somewhere in the manual
