Question 1 - When recording bass via DI, do you need a programme so you can change the settings much like the gearbox software for the toneport? If you do, what ones should i look into?

Question 2 - I like to record covers with the song faintly in the back ground just to keep me in check with vocals etc. Is their a software i could use to find out the tempos of songs so i could programme the drums and insert at the end?
