Dave Smith Instruments SYNTHESIZERS

Forgive me if this topic has been beaten before. I have a sequence in my PEK using sequence 
four to generate variable clockmod values to the sequence. I am wanting to slave my PEK to 
Protools so when I hit play in Protools the PEk sequencer and drum machine sequencer starts 
at the same. So I go into globals and change from the internal clock of the Pek to midi in. At 
this point the PEK syncs and follows Protools tempo but completely gone is my clockmod to 
the Pek sequence so all I am getting is a stream of  steady 8th notes with no variations from 
the clockmod. I am probably doing something stupid but would really like to find a way to 
make this work! Any suggestions or solutions are welcome. Thanks to all! Best regards, Paul
