Checking Your Operating System Version
If you’ve just purchased your OB-6 new, OS 1.5.5 may already be installed. If not,
and you want to use the new features just described, you’ll need to update your OS to
version 1.5.5 or later.
To update your OB-6 OS, you’ll need a computer and a USB cable, or a MIDI cable
and MIDI interface. To download the latest version of the OB-6 OS along with
instructions on how to perform a system update, visit the Sequential website at:
https://www.sequential.com/updating-ob-6-os/
To check your OS version:
1. Turn on your OB-6. The OS version number is briey displayed in the main
bank/program display.
2. If your OS is out of date, download the latest version from the URL above and
update your instrument using the instructions included with the download.

Arpeggiator Beat Sync
is option quantizes keyboard performance of the arpeggiator so that notes are
quantized to the current clock divide setting. Previously, changing notes or chords
on the keyboard during arpeggiator playback would retrigger notes whether or
not the note was played precisely on the beat. With this option enabled, arpeggiator note playback occurs only on the beat — regardless of the precision of your
playing.
To enable Arpeggiator Beat Sync:
1. Press the globals button twice to activate the lower set of parameters.
2. Press program selector button 9.
3. Use the bank and tens buttons as decrement and increment buttons to step
through available settings and select on.
4. Once you’ve chosen the desired setting, press the globals button again to
exit.
MIDI Note Output from the Arpeggiator and Sequencer
e OB-6’s arpeggiator and sequencer can now output MIDI note numbers. Any
notes that you hold on the OB-6 keyboard will be arpeggiated according to the
current settings of the arpeggiator and output over MIDI (or USB) as MIDI notes.
Similarly, any notes output by the sequencer will be output over MIDI (or USB) as
MIDI notes. You can use this feature to drive other MIDI-equipped devices such
as synthesizers and drum machines.
To enable MIDI Note output from the arpeggiator and sequencer:
1. Press the globals button then press program selector button 5 (param xmit).
2. Use the bank and tens buttons as decrement and increment buttons to
step through available settings and select either
cas
or
nas
. Your choice
depends on whether you were previously using CC or NRPN to send MIDI
controller data to your external device, as either setting will send MIDI
notes out. Choose
cas
if CC. Choose
nas
if NRPN.
3. Once you’ve chosen the desired setting, press the globals button again to exit.
