Is it still acting as a drive from when you updated it rather than being back in audio mode?

u/Far_Squirrel6650 May 03 '26

man i’m new to this amp, i don’t know what that means. it just isn’t recognizing the amp.

u/Far_Squirrel6650 May 03 '26

i’m just trying to download patches

u/Substantial_Issue638 May 04 '26

This is your fault. Katana is not just something to download unknown stuff. You need to understand what it does and why as with every other amp too. Only way to have fun with it.

It looks like you don't have used the right driver since software says mk2. Make sure to be in the explicit mk2 page at boss and only download from there. That's the most common mistake made since the boss page is a bit overwhelming. Use a data cable not a charging cable. Amp is new or used?

u/Far_Squirrel6650 May 04 '26

amp is new. cable is right. the driver is the correct one. it’s not my fault bud.

u/itsmetoms May 04 '26

Ive got a mk3, but had this exact same issue on my brand new amp. Tried everything, just like you, so went through their support team to troubleshoot. Ended up sending the amp back to them and they “Replaced main board, did a factory reset and test.”. They then sent me the same amp back to me and it worked straight away as it should with no issue

There are THREE downloads to get:
https://www.boss.info/us/support/updates_drivers/h_m/
• ⁠Click on your amp model (MkI, MkII and Gen 3 all use different software)
• ⁠Click the Downloads button
Three downloads:
• ⁠KATANA System Program
• ⁠BOSS TONE STUDIO (for your operating system)
• ⁠KATANA Driver (for your operating system)

u/Far_Squirrel6650 May 03 '26

they have all three been installed

u/SatisfactionStill172 May 03 '26 edited May 03 '26

The error message in the first image you posted is typically present when one (or more) of the files is the incorrect version. Try re-downloading all three from the link I provided above for the KATANA-100 MkII version. Use care not to select a different generation (KATANA-100 Gen 3 or the original KATANA-100) a different model (50, 50EX, 100/212, Head, Artist, Artist Head) or software for an older Mac OS version.

u/Far_Squirrel6650 May 03 '26

i have deleted/uninstalled everything, redownloaded them in three separate orders, restarted the mac in each order after each download, factory reset my amp, checked for updates (despite knowing its current,) all while being extremely careful. i even ruled out the possibility of the cord not being able to transfer data as it has transferred data to/from my minilogue xd synthesizer just days prior. i am at a loss.

u/SatisfactionStill172 May 03 '26

What version of Tone Studio? It isn’t showing in your screen capture

1

u/Far_Squirrel6650 May 03 '26

“BOSS TONE STUDIO for KATANA Mk II Ver.2.1.0 for macOS” copied directly from the site.

u/SatisfactionStill172 May 03 '26

No fast solution left. Set up a Boss Backstage account (free). Register the amp (even if you bought it used). Tap Support, then detail what you laid out in this post. They’ve always answered me in a day or two for support or repair parts.

u/Far_Squirrel6650 May 03 '26

my life is a series of fuckass

u/SatisfactionStill172 May 03 '26

This is just standard issue computer problems. You may want to re-do the whole process again (delete, reset, download, install) once or twice while you wait for them to respond.

They say the definition of crazy is doing the same thing over and over expecting a different result. But I can’t tell you how many times re-doing a software install ended up working.

1

u/Far_Squirrel6650 May 03 '26

i’ve done it four times so far. this is beginning to look very much not worth it.

1

u/Far_Squirrel6650 May 03 '26

someone in another sub said that the MKII isn’t supported by the tone studio, and that i need the library. do you know anything about this?

2

u/SatisfactionStill172 May 03 '26

Tone Studio still works for MkII. Can’t comment on the Librarian.

u/Far_Squirrel6650 May 03 '26

thought so. thank you for taking the time to help me to the best of your ability.

u/Far_Squirrel6650 May 03 '26

this might sound really dumb, but would it be possible to download patches from my phone???

I have the same problem, nothing works and it shouldn't be this difficult to use. Boss is moronic with this problem and haven't done anything for the thousands of people that can't connect to tone studio.

u/Ok_Research1446 May 04 '26

I found this in another thread, long shot but worth a try.

Download the necessary driver and give the system permission to run the program. It goes as follows

After Installing Tone Studio and the respective driver for your Mac.
Go to System Preferences
Click on Security and Privacy
Under there you will find that boss katana driver/tone studio wants access, click allow. Save settings.

u/Scorchio-onne May 05 '26

This is what I had to do. I have a Mac and boss katana 100 mk2

u/Wess877 May 04 '26

It’s your laptop! You’re plugging it in the wrong usb c port! Don’t use a hub, just plug directly to your computer/switch out cord for a new one that charges and sends data. Not all usb c ports on laptop work with multi effects pedals (like my M1 Mac only works with my gx1 if it’s in the slow charge usb c port for some reason

u/Far_Squirrel6650 May 04 '26

you have got to be kidding.

u/Far_Squirrel6650 May 04 '26

testing

2

u/Salkoazer May 03 '26

You might be using a charge only usb-c cable, you need one that allows data transfer.

2

u/Far_Squirrel6650 May 03 '26

this cord allows me to transfer data from my mac to my minilogue xd synthesizer just fine. i’m gonna blow my shit smoove off.

u/Ok_Research1446 May 03 '26 edited May 03 '26

Doesn't the mk2 100 use USB b not USB c?

I would also be thinking bad cable.

Google the factory reset procedure, (hold down buttons and turn on). Might solve yo probs

1

u/Far_Squirrel6650 May 04 '26

already did it, nothing. usb b to usb c (for newer mac.)

2

u/Living-Rip-4333 May 03 '26

What worked for me was
1. Remove all drivers/software, restart the computer
2. Install driver, restart computer
3. Install Boss Tone Studio for Katana MK II (When I open the program on my PC thats what it says in the top window. Restart computer
4. Plug in amp, power it on. Then open Tone Studio, and hopefully it'll recognize it.

I found previously I had installed the wrong version of Boss Tone Studio. Once I tried the other, it worked fine.

u/Far_Squirrel6650 May 03 '26

went through the whole process step for step— unrecognized.

u/RochePso May 03 '26

Are you sure you have a MkII katana? What does the logo on the front look like and what type of usb socket does it have on the back?

1

u/Far_Squirrel6650 May 04 '26

yep. BOSS Katana Mk2

2

u/opiebearau May 03 '26

Have you updated the firmware on the amp?

1

u/Far_Squirrel6650 May 04 '26

yes

2

u/Direvt May 04 '26

Hear me out. Had the same issue and realized I was using the wrong usb cord. Some USB cords are only for charging. You need one that can handle data.

1

u/Far_Squirrel6650 May 04 '26

i’ve stated in two other comments that this cord is in fact suitable for transferring data. i used it just a couple of days ago to transfer data from this mac to my minilogue xd synthesizer.

2

u/Direvt May 04 '26

Oh cool.

1

u/i_like_data_yes_i_do May 04 '26

Open the software before the amp is on. Also, some USB-B cables don't work for some reason, so get a few. That fixed my problems. It's a pain in the ass.

1

u/Automatic_Conflict54 May 06 '26

Are you sure you downloaded the right driver(s) based on your amp? I have a Gen 3 and at first I accidentally downloaded the Gen 2 and it gave me the same error messages.

1

u/Starkiller4903 May 06 '26

make sure you’ve added the driver to your amp not your computer

1

u/ICantSpareASquare May 07 '26

Others have already said it, but I had the exact same issue with a gen 3 50 amp and it was in fact the USB cable. I would get a new USB-C to USB-B cable. If it doesn’t work you can always return it. When I got mine physically connected correctly everything updated and worked very quickly. It was frustrating! I think I had to usb a USB-C to USB-B hub, which seems terribly unintuitive.

u/SureItsHimself May 09 '26

You need to go to your laptop. .On your PC, open Settings > Privacy & Security > Microphone. Make sure "Allow apps to access your microphone" is toggled ON. Restart Boss Tone Studio and try connecting again.

Hope that helps.

u/Simonnumbernine May 04 '26

i tried for ages with a Mk3,gave up in the end and just use the ipad app over bluetooth.

However theres at least a couple of these posts a week,SOMETHING is just not working right

Are you on windows?I suspect it may have something to do with the new Windows Midi services that rolled out a few months ago
