Download tsl files.

I got this app a couple years ago. It was working fine, I loved it. Lately, I can not download tsl files anymore. Can you please help me out?

Katana Go again on the Market

As the Katana Go is now back in the market it would be great to add it the the Librarian App. Any plans in your development?
I got the great news today that now Katana Go is supported by the app. Thanks to the team! You are great!

Response from developer

The KATANA:GO is now supported.

Just a bit limited

All the patches are great, but a bit limited. Maybe a few rhythm patches would be great. Keith Richards, Stone Roses, and some C & W, Chet Atkins, and Buddy Holly, for variety.

Response from developer

Possibly in the future if there is enough demand.

Soooo Unreliable

I just got this thinking I wouldn’t have to lug around a laptop for changing my patches but soon discovered it constantly hangs and has to be restarted at least if you are doing imports and exports like me. I’m on a new iPad BTW connecting to a MKII 100. It sure would be nice if it only worked!!
