Pirate %/s (KMS RED and GMS Unleashed)

Quick question, so for AB's soul seeker, each orb can hit up to like 7 times before it goes away right?
Is there a cap on the number of orbs she can have out at once? (assuming that by pure arse luck, all of her orbs manage to recreate themselves 7 times)?

There's nothing that would indicate there is a cap on the total number of orbs on the screen at once.
