Roland´s TB-03 (remake of the legendary TB-303) has an slide effect you can add to a note to let the note 'slide'. But there is also an tie you can use to hold one note to the next note.
Here is an example with 3 steps to create context for my question:
When I add an slide on the first step, then step 1 holds the note till step 3. When there is a note on step 2 then the note will be ignored:
I my mind, both do the same. Who can tell me what the difference is?
