Yes, Disting is one of the best bang-for-the-buck utilities in the modular world. It can do everything, though only one function at a time, to help you decide when you it's time to invest in a dedicated module to perform a specific function. I bought one early on as I was building my rack, and it helped me fill in what I was missing. Now I mainly use it as a tuner, but every now and then I will dial in one of the other algorithms.
Have fun and good luck.
