Relocating Keyswitches is easy

Right: so I copied the script you gave me onto the edit screen and clicked "Apply", but nothing changed. Here is what I entered for midi channel, highest and lowest keyswitch and transposition:

on init

 declare $channel

 declare $lowest_ks

 declare $highest_ks

 declare $transposition

end on

on midi_in

 $channel := 1    

 $lowest_ks := 12

 $highest_ks:= 27

 $transposition:= 24

if ($MIDI_CHANNEL = $channel -1)

 if ((($MIDI_COMMAND = $MIDI_COMMAND_NOTE_ON) or ($MIDI_COMMAND = $MIDI_COMMAND_NOTE_OFF))...

 and ($MIDI_BYTE_1 >= ($lowest_ks-$transposition)) and ($MIDI_BYTE_1 <= ($highest_ks-$transposition)))

  set_event_par($EVENT_ID, $EVENT_PAR_MIDI_BYTE_1, $MIDI_BYTE_1 + $transposition)

 end if

end if

end on

So what am I doing incorrectly?

Got you now. I made the mistake of putting in the key numbers of where I wanted the transposed keyswitches to end up! SO now I have put in the numbers you suggested!

So now I have pasted in the following script, and changed the MIDI channel in Kontakt Player from OMNI to "1":

on init

 declare $channel

 declare $lowest_ks

 declare $highest_ks

 declare $transposition

end on

on midi_in

 $channel := 1

 $lowest_ks := 36

 $highest_ks:= 51

 $transposition:= 24

if ($MIDI_CHANNEL = $channel -1)

 if ((($MIDI_COMMAND = $MIDI_COMMAND_NOTE_ON) or ($MIDI_COMMAND = $MIDI_COMMAND_NOTE_OFF))...

 and ($MIDI_BYTE_1 >= ($lowest_ks-$transposition)) and ($MIDI_BYTE_1 <= ($highest_ks-$transposition)))

  set_event_par($EVENT_ID, $EVENT_PAR_MIDI_BYTE_1, $MIDI_BYTE_1 + $transposition)

 end if

end if

end on

But still no change!

I set transpose to 24 simply to move the keyswitches right out of the way. I did click on "Apply", but didn't scroll down the script, so didn't see that it had highlighted a line, as per the screenshot (presumably it will highlight each line that needs attention successively), so there may be more. What does the highlighting indicate that needs correcting?

My apologies for this being long and drawn out. S I may have mentioned, I developed RSI from my employer's "budget" computer keyboards many years ago, just as MIDI started to appear, and have only been able to return to music recently. So I am on a massive learning curve, knowing very little about MIDI itself, and have never done scripting before! So although I appreciate something of what MIDI offers, I am a complete beginner when it comes to technical stuff like this!

I have managed to create a work-around, simply by using the transposition setting within Cantabile, my vst host. So I h, using the top octave for tave Icon Bass transposed to send its keyswitches out of the lower range of my 61 note keyboard, and then transposed the guitar vst upwards, using the top octave for the chords, with the keyswitches landing in the middle of the keyboard. IT limits me to a single octave for bass playing, and of course the single octave for the guitar chords- the latter is fine, but the whole thing is a little clumsy. But until I can get the scripting sorted, it will have to suffice.

Many thanks for your patience

Ahaaa!!! Progress! I now have it that the pink keyswitches have been transposed (note numbers 26 - 41), but the yellow and green ones (note numbers 44 - 51) remain in play!

Incidentally, as an aside, I have spent some time exploring the Mapping Editor, which I have is only accessible via "File/New Instrument", which gets placed below the Guitar vst. The New Instrument displays (DEMO) in red, and I get the message "Only available in full Kontakt", which I suspected. So the normal "spanner" icon in the top left corner of the screen isn't there, replaced by a white rectangle with two sizes of the "Settings" icon, which bring up the "instruments options" dialogue box. Ho hum!

But at least a part of our objective has been realised!

So this is a copy and paste of what the script looks like now I have pasted it into the edit page:

on init

 declare $channel

 declare $lowest_ks

 declare $highest_ks

 declare $transposition

end on

on midi_in

     { ***set these 4 values*** }

 $channel := 1

 $lowest_ks := 36  { current keyswitch }

 $highest_ks:= 51  {   note numbers  }

 $transposition:= 24 {  how far down you want them transposed  }

           { (negative value will transpose upwards) }

if ($MIDI_CHANNEL = $channel -1)

 if ((($MIDI_COMMAND = $MIDI_COMMAND_NOTE_ON) or ($MIDI_COMMAND = $MIDI_COMMAND_NOTE_OFF))...

 and ($MIDI_BYTE_1 >= ($lowest_ks-$transposition)) and ($MIDI_BYTE_1 <= ($highest_ks-$transposition)))

  set_event_par($EVENT_ID, $EVENT_PAR_MIDI_BYTE_1, $MIDI_BYTE_1 + $transposition)

 end if

end if

end on
