This is almost certainly because the LFOs, Delay and/or Arpeggiator are set to sync to MIDI Clock. To check this see if the Clock parameter in the Global Mode is set to Ext. ( refer page 36 ) If it is set to External then setting this parameter to internal will restore the operation of the LFOs, Delay and or Arpeggiator. If you wish these to be synced to MIDI Clock, leave this parameter in External and confirm that the sequencer is actually sending MIDI Clock. A lot of software sequencers default to NOT transmitting MIDI Clock. If the LFO / Delay / Arp is stuck / not functioning and you have the Clock parameter in the Global Mode is set to Ext, the sequencer is not sending MIDI Clock. There is no other reason.
