MTD 1024 - Software for v11.7.10 Big Sur

I've got a MacBook Pro (Quite an old one) running OS 11.7.10 Big Sur. unfortunately the version of the Midi to DMX software i downloaded is not compatible.

Is there an older version i could download which will work.

A link would be great.

Dont really want to have to purchase a new macbook !

Many thanks

Rob
