Does the OB6 have the different Portamento Modes that the OB-8 has?
On the PAGE-2 of the OB-8 there are Match and Quantize portamento modes:
Match Mode ON: "All voices will portamento at the same rate."
Match Mode OFF: "All voices will portamento at slightly different rates."
Quantize Mode ON: "Quantizes the sliding portamento into semitone steps."
The OB6 has four portamento modes:
Fixed Rate (the slide time will vary depending on the distance between notes on the keyboard)
Fixed Rate Legato (same as above, but will only occur when notes are played legato (overlapping each other))
Fixed Time (the slide time will remain the same no matter the distance between notes on the keyboard)
Fixed Time Legato (same as above, but will only happen when notes are overlapping)
That's it.
