MIDI Address for key assign to chord pads in Global mode

Post by kedilevi »

Hi everyone,

I’m a proud owner of a Kronos 2, 88 Titanium edition for 5 years already, but it still makes suprises or headaches.
And one of this headache now is to play a chord with one key.
I’ve gone through all the threads I could find, I tried the chord mode in program and combi mode, the pads assing to notes in global mode but I want something more “dynamic”.
What I mean by this is: as I play mostly with lower base keys in octave added to the chords(ex.: D2,D3,D4,F4,A4) to get more deeper and reacher pad/string sound, I need both of my hands for this, but with pads assigned to the lower keys I could do this with one finger and free up my right hand to do other melody lines. I know, in global mode, pads can be assigned to keys, but this is static, in all combis would be the same, and if a song has a keychange or another song in different key, then... this could get very messy realy fast.
I want to be able to change the assigned keys to chord pads in global mode with Setlist/Combi change. And that’s imposible in the Kronos itself, as I know. So... I started digging into midi sysex messages. I tougth it could be possible to change this global setting with an external device, a laptop or a raspberry pi running a script, what listens on midi out port for the Setlist change message and sending back a sysex message to change the key for chord pad in global mode.
But I can’t find the coresponding sysex message for these parameters. I even sniffed the usb communication betven the kronos editor software and the kronos with wireshark, but for my surprise the editor software sends to the keyboard the whole global hex dump after parameter change, not just a sysex message. And this takes almost 2 seconds, what in a live gig it’s a too long time.
I would need an address like the VJS X : F0 42 30 68 43 0F 00 00 24 00 00 00 00 F7 or VJS Y : F0 42 30 68 43 0F 00 00 25 00 00 00 00 F7, as appears in MIDI-OX soft, what the sript can send back to the keyboard. But I can’t find such address in the documentation.
If anyone knows more information about The [44] Parameter Change command in the KRONOS_MIDI_SysEx.txt file, or a more detalied documentation about Kronos Midi, I would realy appreciate this info.

Any help would be much appreciated.
Thanks

The Korg nanoPAD2 is mapped automatically by the Kronos to the Chord Pads, and is velocity sensitive. Might that be a solution? There's plenty of room on the top deck of the Kronos 88-key, for the nanoPAD2.

MIDI-OX is much more than a diagnostic tool, so one way to achieve what you want could be to use its data mapping function. The Kronos pads are simply generators of multiple MIDI note on/off messages. MIDI-OX can do that super quickly and much more. Since you seem to be OK using a laptop while you play, you could use MIDI-OX to create such MIDI functions with your Kronos. Make sure to turn off local control in your Kronos to avoid MIDI feedback.

Below is a basic example with the note E2 (MIDI note = $40), also playing Bb5 (MIDI note = $82). Obviously dissonant, but you get the idea. Then add as many other maps as needed for that same triggering key to create complex chords. You don't even need to hear the triggering note if you prefer by turning off the clone option for that particular map (this will also be needed to avoid launching 4 or 6 times the same triggering note in 4 or 6 note chords, etc.).

IMPORTANT #1 : don't forget to add MIDI note off messages as on the example for each triggered chord/map note to stop them when you release the triggering key. And those off messages must appear below the note on ones (chronological order is important).

IMPORTANT #2 : if you use this to sound a Kronos SGX-2 piano, turn off sympathetic resonance, otherwise all kinds of ghosts notes linked to the SGX-2 piano internal resonance maps will be sounding. :wink:

Finally, you can also use the MIDI-OX patch mapping to determine which program or setup will start whatever chords/maps you want. There is no limit, it just takes a while to program the stuff. I often use MIDI-OX to do many other things as well, for example change setup, program, effect, intonation table, pressing a key or whatever.

Hi,

Thanks for the quick replys.

voip - Yes I know about nanoPad2 and I tried other methods too, like in Program mode, putting together more samples transposed to each other, or using the Chord mode.
In Combi mode adding the same program to multiple layers assigned to different midi channels, setting up the virtual pads on the respective channels... and tried everything what is described in this post: http://www.korgforums.com/forum/phpBB2/ ... rd+one+key...
But the problem is the pads assignment to the keys. In a a song which is in Dm, a key change to Fm leads to play in Fm with right hand and for ex. D base note with the left, as the pads assignment to keys remains the same, and I want to avoid that, because in a 1.5 hour of live gig with 16-17 songs, where some song have even 3 key changes, it can get really confusing. Its the same story with the pads.

KK - Thanks for this info, I did'nt know about this feature of MIDI-OX. Its interesting, I will look into it.

It's worth bearing in mind that the nanoPAD2 has four "Scenes". In each Scene, the top row of 8 pads is mapped to Kronos' Chord Pads, but the lower row of 8 pads can be assigned up to 4 notes each, so potentially 32 different four note chords.

Now let’s think of a reason why it CAN be done...

You don't need to go to Global Mode to assign chords to the virtual pads!

Each Program can have up to 8 chords stored with it.
Same for Combi mode.

When I last gigged, I assigned a Combi for each cover song.
Each song of course would have its own chords as needed.

Even better, I triggered them using an FCB1010 foot controller.
In Global mode you can assign CC or notes to trigger the virtual pads.
So I assigned the same CCs to my FCB foot pedal board.

Then I could play bass guitar and step on pedals to trigger chords (or samples).
Or play keys with 2 hands and extra chords with my feet.

Fun times.

Yes, hopefully the OP found them useful.
