Arduino Zone Only Up To 32 zones?

[Royur]

Sorry if this is noob question.

But is the Arduino DSC can only read 32 zones? As stated here:

"Memory usage can be adjusted based on the number of partitions, zones, and data buffer size specified in src/dscKeybusInterface.h. Default settings:

Arduino: up to 4 partitions, 32 zones, 10 buffered commands"

Or can i change it to 64 in the src code?
