Hi Folks.... Struggling with a puzzle here!

I'm using a bass pedalboard to play one of the timbres of a combi, I have the timbre set to midi channel 3 and it plays fine but I can't get my expression pedal to control the volume of that timbre. The pedal controls all the other timbres (or at least the one's set to 'Enable for Pedal' on Midi Filter P3) but not the timbre controlled by the pedalboard.

I have the expression pedal set in Global to 'Volume (CC#7)', I realise that setting it to Master Volume would work but I need to be selective about which timbres it affects. I've been through all the menus multiple times but can't see anything that works... Any ideas?

Your bass pedal needs to send the volume messages on the same MIDI channel as the timbre.

I wonder if a Karma Midi I/O setup could work a solution...

Using a Karma module is indeed the solution. I had a similar problem a while back trying to use the sustain pedal on only one channel of a Combi. I'll post more when I track it down.

I found what worked for me - adapt it to your situation..

thanks to mikeless for this explanation:

On Kronos, control information like sustain is only generated on the global channel Gch (which by default is channel 1), so the first thing you need to do is to relay that information to channel 2. This can be done with a Karma module: In the Karma setup screen, use any initialised module but make sure the Run, Thru In Zone, Thru Out Zone and Thru buttons are unticked. Set the input channel as your global channel (1) and the output as channel 2. When you enable Karma this will send control information like sustain to channel 2 also.

Secondly, if you don't want sustain on channel 1 sounds, then use the MIDI filters to disable damper for those timbres in the Combi.

Ah.... thanks guys, I'll look into the Karma module solution. That's really helpful, thanks so much!

Let me try to augment my earlier post regarding using a Karma module to solve this:

On Kronos, control information like volume is only generated on the global channel Gch (which by default is channel 1), so the first thing you need to do is to relay that information to channel 3. This can be done with a Karma module: In the Karma setup screen, use any initialized module but make sure the Run, Thru In Zone, Thru Out Zone and Thru buttons are unticked. Set the input channel as your global channel (1) and the output as channel 3. When you enable Karma this will send control information like volume to channel 3 also. Now, since you don't want volume control on channel 1 sounds (and/or other sounds), then use the MIDI filters to disable volume for those timbres in the Combi.

I hope this helps. It worked for me when I was trying to do the same thing - except applied to the sustain pedal, not volume.

Thanks yeskeys, that makes more sense now. I'm a bit of a newcomer to the Kronos and haven't delved into Karma yet but it's a good learning process trying to work these things out so that's really helpful. I'll get stuck into the manual and menus and hopefully will get it solved... thanks for the help!

Thanks also to psionic. My bass pedals are the Hammond SPK-130G (bought for my SKX) which don't seem very configurable... I'll investigate further though if I get stuck! Thanks for your time. Smile

That's great that you got it working. While I appreciate the thanks, I was merely passing on info that I myself learned on this forum. Good people up here.

I set up a Yamaha MFC1010 foot controller on my M3. I set the first 8 footswitches as momentary, which I then assigned to trigger the 8 touchpads, which would play as long as I held the footswitch down.
Then I set up switch 9 to turn Karma on and off. I think I set it to latch.
I set up the last switch to Latch Karma on or off.
Then I had the sweepable pedal assigned to sweep through the 8 Karma Scenes - I had the travel of the pedal divided into 8 discrete evenly spaced zones so it was easy to dial in the scene I wanted.

I did all this so I could play the guitar and add synth and Karma-fied percussion/loops with my feet. During rhythmic Karma patches, usually I'd restart the pad every couple measures to stay in sync with my drummer. It all worked great, I'll set it up on my Kronos once I can tear myself away from playing it.

Note I set all this up without using Karma modules for any of the programming, I was simply using MIDI CCs (continuous controllers). I'm not gigging now, but this system is amazing if you are just playing and want your Karma band to follow YOU -

Hey yeskeys, that's a pretty nifty use of your foot pedals!

I did something very similar with my FCB1010, but just used it to trigger the 8 pads. Most of my cover song Combis have notes and chords assigned to the pads, which I then trigger with my feet when I need a 3rd hand playing keys or when I'm playing bass guitar and want some keyboard parts at the same time (a la Geddy style).

Now that I'm not gigging for awhile, I think I'll re-purpose my foot controller to do some one man band KARMA stuff like you've got.

psionic311 - I'm trying to find the thread where you break down some FM/MOD7 techniques - something about opening a window and stepping through a bunch of waveshapers(?)...can you point me to it? I'm ready to start exploring MOD7....
Thanks!
