Trying to find out if theres a way to send tap tempo to my Katana head from my MS-3, hopefully globally

Sadly there is no published Katana MIDI specification

( But I suspect Katana does NOT support external MIDI Tap Tempo control , unless you use SYSEX  - or  PrimovaSound MIDX-20

Katana MIDI Implementation was reverse engineered by a few gurus here

Note: Tap Tempo equivalent to setting delay time, but it
      averages time between button presses.

Delay Time (1,..,2000ms)
60 00 05 62 --> 00 01 .. 0F 50

Note1: hhll is an 11-bit value representing ms intervals between taps
       (Max 2000). Because sysex data is limited to 7 bits, encoding
       is:

       hh                            ll
       0 0 0 0 b10 b9 b8 b7    0 b6 b5 b4 b3 b2 b1 b0

       So, the maximum value would be 0F 50, or

       0 0 0 0 1 1 1 1     0 1 0 1 0 0 0 0
