jammr Forum

Hello: I just registered today. With the shelter in place restrictions and closure of bars due to the Corona Virus, my band wants to try to get together online. I am not real high tech when it comes to programs like Jammr. Do I need a program or software like Garage Band to use Jammr? I need to get one of those 1/4" jack to USB cables for my guitar.
I will appreciate any recommendations regarding cables or software that work best with Jammr.

Thank you,
Lawrence
