KATANA-AIR, KATANA-AIR EX: Does it automatically switch from standby mode to ON by detecting audio signal?.

JC-22: What kind of footswitch can I use with this unit?.

KATANA-AIR, KATANA-AIR EX: How do I export patches saved in BTS for KATANA AIR to the KATANA-AIR unit?.

A Teensy 3.2 would work just as well with ths options. Inside view with messy wiring and extra holes from a previous project:Īnother inside view but with a Teensy 3.6, MIDI through (untested), an extra power jack for daisy chaining, and two TRS jacks (only one is connected in the picture). These sketches have only been tested with a Teensy 3.2 and a Teensy LC. I googled these pictures that show the modification for 5v microcntrollers: topic=80421.0 attach=130856 image

I don't know if this is necessary but, I originally tested this project with an Arduino Nano and I "cut the trace inside VBUS jumper" on the host shield as mentioned in the second paragraph under the Power Options part of this page: shown here.

Wiring shown above does not include expression pedals or MIDI through, see images directory for that diagram. What got me started on this project is a forum thread created by the author of the MS3 library: If you don't need 5 pin MIDI IN/OUT, you can just skip this part. I used a MIDI break out board but there no reason not to build your own MIDI in/out circuit. The working prototype uses the library and a USB host shield Here is some excellent information about sysex messages and Katana amps: Note, this library is included in the files above (top of page) and has been modified to work with the Katana instead of the MS3. I found this library made for the BOSS MS3. Additionally, there is a checksum included in each sysex message. Roland/Boss guitar gear uses a non-class compliant USB device for midi control. Also, you should use the modified versions of the MS3 library included above (top of page).Īlong with the Teensy 3.2, I use a Mini USB Host shield like this one: along with the host shield library. You must select the Teensy option "MIDI" when powered externally (not connected to a computer).

** Note I had to compile the sketches with the "fast + LTO" setting or debug, otherwise the USB mini host shield would not work. On this version there is no tap-tempo and no expression pedal input. So, you'll need to change the programming if you use it differently. The LCD and LEDs are programed to be off when you switch channels, meaning the controller expects all effects to be off. This version is really just for testing your hardware or if you just want a starting point for your own code.

In the Simple sketch version, you will need to code the LCD and LEDs to work for your needs. This version has been tested on a Teensy 3.2 and a Teensy LC. There is also a BOM (parts list) in this thread. This is experimental and requires some coding on your part.Įxpression pedal jack input directly connected to controller and external MIDI clock IN is being worked on but not yet complete, no ETA. Select Green, Yellow, or Red effect functions from the three lower foot switches.Īn expression pedal can be connected to an external MIDI controller to control 1 effect only. LCD displays FX status, amp name, tempo, loop status, bank/fx mode, and channel number. If you’re looking for a more complete external MIDI to Katana you could buy the MIDX-20.

Some CC and PC messages from the MIDI in port can be received and translated to sysex and forwarded to the Katana.

Midi IN - control Katana patch and FX from an external MIDI controller. Selectable mode for 3 foot switches, toggle either one or both FX/MOD, Delay 1/FX, and Reverb/Delay 2. Included in the : Katana_USB_MIDI version There is a forum thread reguarding updates and functions: Gumtown from the Vguitar forum deserves recognition for rewriting most of the code and adding a great deal of functionality. In the Katana_USB_MIDI version, LCD and LEDs are updated from the Katana's USB MIDI messages. ** If you get stuck, I may not be able to help you. **Consider this unsupported beta software. It seems stable however, it has only been tested by two people that I am aware of. Sending MIDI OUT from the footswitch is also possible. This controller can also listen to a 5 pin MIDI IN port and can be programed to translate MIDI messages (PC, CC, etc.) to sysex and forward those to a Katana. An expression pedal attached to an external MIDI controller can be used but requires you to adjust/write some code. I'm working on an expression pedal input. The code emulates a GA-FC without additional footswitch connections (although there doesn’t seem to be any reason that’s not possible). The foot controller sends sysex messages to the USB port on the Katana.

This is working prototype of a MIDI foot controller for a BOSS Katana using a Teensy 3.2. A Teensy based USB MIDI foot controller/translator for Boss Katana.
