Autosustain issue

Hi, im using this fantastic script but i have an issue.
Im using it on a rackspace where i use with an arp.
When i switch to the next rackspace the arp continues to play. My wish is that changing rackspace the arp stop to play when i start to play the new rackspace. Can you help me?

This is probably because you have Patch Persist enabled. Do you really need it for this Rackspace?

Id like to keep the arp sounds before to start to play the rhodes sound of the following rackspace. For this reason i kept pach persist on
