feel free to reach out to me and i can help you figre it all out. (831) 254-7562. also, when purchasing truerta you only need the 1/3 octave scale. the 1 octave scale is free, but all the processors out there use 1/3 octave scale so its best to get that. i ended up purchasing the 1/24octave scale. it was $100 but definitely not necessary for your needs.
