Hidden feature and solution for polyphony problems in Combis

Hi there, sorry about my bad english, i'm a german and i hope you will excuse it.

According to http://www.korgforums.com/forum/phpBB2/ ... hp?t=62564 i thought it would be better to creat a new thread to advice that solutions.

Try this to use Karma to manage sounds, splits and layers in Combi Mode

1) All Channels you would like to group in a scene must have different MIDI Channels, that's what normally happened when you select a INIT Combi.

Example: You would like to group a string and a piano sound in one layer
Piano - Channel 1
Strings - Channel 2
Others - every, except Channel 1 and 2

2) Open Karma GE Setup and disable below the GE setup line (first grey line) the Run button in section A

3) Open Perf RTP and do the following setting:

Group: Key Zones |Parameter: Thru Inside Zone | Button:Enable A | Assign: Switch1
For the next scene you have to increase button and the assigned switch

4) Open Karme GE Setup,take a look at MIDI I/O section and be shure that every scene have different channels (normally it set 1,2,3,4)

5) Enable Karma and select the control assign to RT Knobs/Karma by pressing the hardware buttons on left side or using control surface

6) Now you can select by using the "karma scenes switches" the scene you would like (it's blinking)

7) With the Karma Switches below you can activate/adress the timbre you want in that scene, maybe step to control surface to have a better view about.

Finally it all works like a mute/link grouping at a vca console or a snapshot function.
If you unterstand that fact it will give you a powerfull tool to layer, group and switch between those sounds/layers/splits without changing or steping combis.
You could create a "combi in a combi" and use the karma scenes to switch and handle different sounds at the complete keyboard zone,one octave or whatever.

Furthermore the discussed "MIDI-Kill-Button" is there, you only need to switch MIDI-Status to OFF, it will increase polyphony by cuting midi in to the engine, i've tested it with Double Screamer wich takes a lot of power.
Overall it's always better to set all timbres you don't need to MIDI-Status OFF

Hope it helps

Hi,

Any way to change volume by the same process?
Fr exemple, when I press Scene B change sounds and reduce volume (or any other parameter)?

Thanks

I'm not sure, as far as i know stephen is working on it, in my opinion karma actually does not affect any control changes beyond it's architecture, but i'm not a karma profi so let anybody know if it can be done.
But there is a solution, copy your timbres and store the same sounds with other volumes and use scene switches to manage them. Since combis own 16 slots it shouldn't be a problem

Regards

so in this concept the user will use karma to switch between different midi status for each track? so when i'm using a track that i have the midi status set to on and then when I switch to a different scene karma will automatically turn other tracks midi status to on or off... (respectively) ?

that's a nice trick .

This trick will not change the MIDI channel the keyboard is currently transmitting. This trick will use KARMA to redirect the MIDI events generated on the keyboard to a different MIDI channel. Therefore, what you're doing is this: there's no timbre on the global channel, the timbres are on different MIDI channels. Then, KARMA will redirect your playing (on MIDI Global Channel) to the Channels where the Timbres are actually responding. This is like a MIDI hub with selectable output...

It seems to be a lot easier to just create a bunch of sequencial setlist scenes.

I must be missing something crucial here apparently...

and it doesn't seem to actually record the data on the the other tracks either... hold on.. maybe it does.

Maybe if you enable Multitrack recording... or maybe it will crash just as your M3 :(

Hi,

does this trick also work for CC data? Or only for notes? I'm desperately searching for a way to redirect midi CC data to timbres assigned to a different but the global channel...

Hi, thanks for your lot replys.
@.Jens Like i posted above as far as i know stephen is working on to integrate CC in karma 3.0.
This solution is based on problems with polyphony in combi mode, however i think there is a lot of potential in it.
Sure it might be easier to build setlist scenes, but i like it to have controll about different zones by button. I'm a live musician. My band plays about 16 songs at one set and one setlist screen with all songs in it is a must have for me cause i haven't any time on stage to switch between screens and keep it all in mind. To copy Combis sucks and if i must change total effects, transpose, inserts, routings etc. i have to do it to all. Better to drink a coffee in that time. Additionally, important for me, i have (16)x(karma scenes) more space on my screen.
Finally i'm a friend of order and system on stage, to much technical mistakes has occurred in past. My band change every gig (mostly 3 times a weak) our setlist, so it's better for me to work with one entry per song.

Regards

You are probably right. Like we say, whatever floats your boat!
:)

I find it much easier, specially in a live environnement, to move up sequentially in setlist slots than remembering what button to press and when to press them.

But that's me!

yeah when you think about it, it does kinda complicate something that setlist made SUPER easy... but at the same time... this will allow you to use less combi slots (unless Korg or course gives us some more slots.)

I must confess, maybe it's also a bit of habituation since triton times.
Anyway, that's the fact that i love on in this keyboard, beside it's incredible sound. Korg has implemented so much capabilities that everyone could use it in that way that works comfortable to him. Limitations are very less on kronos :wink:

And changes in combi to a sound (tone adjusts, effects) could be done in one combi, i work a lot on my sounds and if i have 4 combis with the same pad in the first two octaves i need to change and compare 4 combis. If i do it at gig and step to the next setlist slot all changes in my pad that i need at the whole song are off
