How can I remove quotation marks from a list received from UDP?

I'm writing a program in Processing to draw an envelope. I send the envelope data to max/msp via a UDP message. My Processing code contains this to send the message:

OscMessage myMessage = new OscMessage("apply");
String output = "0, 0 50 1.0 2450 0.75 100 0.75 1400 0.0 900"
myMessage.add(output);

In Max i'm receiving the message and now i'm trying to send it to a line~ statement. The problem is, I receive quotation marks around my list, so now the line~ statement does not recognise it.

Is there a way for me to remove the quotation marks or maybe something else I can do for this to work? Below is my patch.
