    (to step 1), when restarting the sequencer, it actually starts on step 2! With our Reset to 16, this problem is overcome. For more details on all features of Oberkorn , please read the whole manual - don’t miss any of it’s cool features! oberkorn e&oe (c) 10-2001...

    Quick Start If you just want to jump straight in and use Oberkorn in it’s most basic form - to play an analogue synthesiser - here’s how to do it: •...

  • Page 7: Cv + Channels In Details

    CV + Channels In Details Oberkorn has 16 steps. (This can be reduced to any number from 1 to 15. More on that later). Each column of three CV pots and 1 switch is a step. There are 16 columns.
  • Page 8: Gate Channels A, B, C

    From the above table, you can see a gate signal is only created when the gate switch is on and there is a clock voltage present. As soon as the clock signal goes low (0v) or the gate switch is off, then there is no gate output. oberkorn e&oe (c) 10-2001...

    CV output. It will not change till the sequencer is either manual stepped or clocked to the next step. The CV controls can be altered in real time to alter the CV output whilst the sequencer is stopped. oberkorn e&oe (c) 10-2001...

    They can be utilised via modifications. E.g. they could be wired to additional jack sockets on the rear panel. Connecting Connect the MIDI sequencer or other MIDI device to the MIDI input of Oberkorn . Connect the trigger outputs to device you wish to trigger. Programming •...

    INT jack socket out The internal clock signal is constantly available from this socket to al- low other devices to be sync’ed to Oberkorn Step 1 jack socket out Each time step 1 is reached, a gate signal is output from the Step 1 socket.
  • Page 14: Reset In Socket: Changing The Pattern Length Of The Sequencer

    This features, like all others on Oberkorn, can be operated in real time to allow you to change the pattern length in real time as the sequencer is running.

  • Page 16: Midi Synchronisation

    MIDI Clock Sync with MIDI Trigger #9 MIDI Trigger #9 (this is labelled ‘SYN’ on the front panel LED) is hard wired to the external clock input of Oberkorn. Each time the MIDI key programmed for MIDI-Trigger #9 is pressed, the sequencer will advance 1 step. This means by programming a string of notes in the MIDI sequencer, Oberkorn can be made to keep perfect time with the MIDI se- quencer.

    Quick Start To Step Control Using MIDI Notes 1/ Program the MIDI to Trigger channels to Note numbers that will control the Oberkorn step number (See MIDI to Trigger Converter section on details on how to assign MIDI Triggers to MIDI notes):...
  • Page 19 Normally Oberkorn should be reset to step 1 when using Step Control Mode. But now try manually stepping the sequencer (whilst the MIDI sequencer is running) using the Step button. See how Oberkorn now will step in a different order! Patch one of the Gate outputs to either the A, B, C or D Control input jacks.
  • Page 20: Step Control In Details

    Counters always count in upwards and in order from 1 to a higher number. (There are counters that count down, but you never see these incorporated into sequencers). The way in which Oberkorn can be made to step in any order is by completely bypassing the counter, feeding your own signals into the 4 bit address bus of the multiplexer.
  • Page 21 Reduce MIDI data flow (give Oberkorn its own MIDI port, turn of MTC and MIDI clock etc). Slight portamento on pitch CV The steps that Oberkorn will jump to for a split second are 1, 5, 9 and 13. 1 is the most often and the others less. oberkorn...
  • Page 22: Midi Sync Switch

    This is done with the MIDI Sync switch. When using Step Control, the switch must be selected to MUX. Then along with your 4 bit MIDI note code pattern (used to select steps), a stream of notes must be programmed for the MIDI Trigger #9. oberkorn e&oe (c) 10-2001...

    Now take the 1st example with 8 pots at full and 8 at zero. Now if you start to change the the levels away from their setings, you will hear the timbre change. All combinations of settings are useable, so just play around live as the sequencer plays. oberkorn e&oe (c) 10-2001...
