 +** There is a new version of the sequencer use the [[paper_bits:​pb206_sequence_recall|PB206 Sequence (Total) Recall]] instead**\\
  
 That is the latest 8 step sequencer for the Paper Bits. One can change steps, speed and the value of two independent CV output. Because it has an external trigger input one can easily synchronize them. It's evan possible to build an 16, 24 or 32 step sequencer out of two, three or more of them.\\ That is the latest 8 step sequencer for the Paper Bits.

-**change ​the speed:\\ +=== Change ​the Speed === 
-The speed can be set withe the SPEED potentiometer or with an external control voltage. For that the Ex-Speed switch has to be set on ON and with a jumper one can select between ​BUS 1 and BUS 2 as the CV source.\\ +The speed of the sequencer ​can be changed with the SPEED potentiometer or with an external control voltage. For the external control the EX-SPEED switch has to be on ON and with a jumper one can choose if the voltage source coming from BUS 1 or BUS 2.\\ 
-If the Sync Sequencer is in the **STEP 1 MODE** ​instead of the speed the control voltage ​will change the individual step.\\+If the Sequencer is in the **STEP 1 MODE** ​one can change ​the active steps with the control voltage, too.\\
  
-**external trigger** +=== External Trigger === 
-If one wants to use an external trigger signal one has to set the Ex-Trigger switch on ON and then use the Gate for the trigger ​input or instead of the TRIGGER ​jumper one can attache an jumper wire to the marked ​pin.\\+If one wants to use an external trigger signal one has to set the Ex-Trigger switch on ON. If the TRIGGER jumper is set the trigger ​signal will come from the GATE BUS. If the jumper ​is not set then one can use the pin marked with IN for a trigger signal input.\\
