Poly/Mono/Legato Switch

Changes OB-E between Polyphonic, Monophonic & Monophonic Legato keyboard modes.

• Polyphonic Mode is used when you want to play OB-E Polyphonically.
• Monophonic Mode is used when you want the Filter and Amplitude Envelopes to re- trigger for each note on.
• Legato means ‘tied together’ and Legato Mode is used when you do not want the Filter and Amplitude Envelopes to re-trigger when playing a note while another one is held. This mode, combined with the correct playing technique achieves a smooth, transition from note to note.

Reset/Continuous Switch

Reset

In POLY Mode, if you play a four note chord the first note of the chord will trigger SEM 1 but the other three notes within that chord will trigger SEM 2, SEM 3 & SEM 4, respectively.

In MONO and LEGATO Modes each note will trigger the same SEM. By default this is SEM 1, but you can make it trigger a different SEM by clicking on the red LED of that SEM.

Continuous

When CONTINUOUS Mode is enabled, each note played, regardless of whether you’re in POLY, MONO or LEGATO modes, will trigger the next successive SEM in what’s known as a ‘round-robin’ triggering mode.

Unison Switch

1. Arguably the most magnificent mode on both the original hardware 8-Voice and OB-E. This triggers all SEMs from a single note-on and is perfect for triggering chords or complex soundscapes where each SEM is set to a different, yet complimentary sound.

<aside> ⚠️ With UNISON selected, OB-E ONLY plays monophonically. We recommend you use MONO or LEGATO Keyboard Modes when building or playing UNISON Patches. If the KEYBOARD switches are set to POLY and UNISON, OB-E will play monophonically.

Split Switch

Similarly, it’s possible to use Split Mode in both Seq SEM 8 or Seq All modes.

In Seq SEM 8 Mode, you will lose SEM8 to the sequencer while retaining SEMs 5-7 in the Upper Split and SEMs 1-4 in the Lower Split. This means that you have a maximum of four voice polyphony in the Lower Split (SEMs 1-4) and three voice polyphony in the Upper Split (SEMs 5-7), in addition to SEM 8 used as the sequencer.

You will find examples of this in the Sequence SEM 8 Patch folder.
