Toggle IFX Limiter On / Off with Foot Switch

[Mersip]

Hi everyone,

I am wanting to toggle an effect (Stereo Limiter) on and off with a foot switch. Essentially it is a way for me to instantly increase the volume on the particular patch and then revert to a quieter sound when needed. I have changed the Output Source to the Foot Switch, but it only works in "momentary" mode (ie you have to hold the pedal down for the effect to work). Is it possible to make this Toggle?

Thanks

I'm trying with a Roland foot switch, but no luck. However, my foot pedal works.

There is a way, but it's ridiculously complicated and will only work in a combi. Also, you will have to use Karma for MIDI control and not as a sequencer. So it depends, if you use Karma as a sequencer for your piece, then it won't work for you. More details later if you are interested.

Hi KK. I am in Combi mode and have Karma on as I'm using Karma Scenes, but I am not using it for sequencing. Can I make that work?

Connect a toggle footswitch in parallel with the momentary one.

Greetings,

Found this thread on KLF, seems that Stephen mentions exactly the effect you are trying to affect.

Granted it was for a different synth but a KARMA solution is always there somewhere… the concept is the same regardless.

IFX METHOD
In the Global Mode > Controllers, set the Foot Pedal assign to CC#12 (FX Control).

And this thread from the MPN forums seems right there somewhere…

Also you could use an IFX as a volume control - select something like a compressor or preamp. Assign foot pedal to wet/dry.

Thanks for the suggestions.

The link to the Kronos Users was interesting, but I already cross-fade using my expression pedal and the IFX's as suggested.

What I am wanting to do is use the other pedal (the Foot Switch) to turn the IFX on and off as a toggle. My Foot Switch is set to Foot Switch in Global and because I use it for things other than effects (for example toggling the rotary on and off in organ patches). I don't want to change the Global setting.

I use Karma, but am not sufficiently good to know how to get the Foot Switch to do what I want here.

Any other thoughts welcome.

First, you need to create a combi with the so-called timbre switching config. Instructions are below. In case you never used this, I recommend to first create it and practice on the original version. You will be half-way to your goal.

I don't want to change the Global setting.

Ah yes, makes sense…


@KK - Thats’s the tutorial I was thinking of… my apologies if I am way OT here

Is there not a method by which the toggle “zone” could be : 0-63 = off and 64-127 = on ?

Where a zone of values is used to act as a switch between, Karma values such as 0,1,2,3 etc. I seem to remember this being described in several places, but I may be conflating methods… when affecting IFX values.

Such this from the KL wiki M3 section:

KARMA switches SW1-SW8 on/off: The value that your foot controller sends over the CC number for each switch can be used to turn the switch on/off. Any value from 0-63 turns the switch off. Any value from 64-127 turns the switch on.

Hello there,

Yes, I programmed some combis somewhat like you mention but of course it will only work with a data pedal, as opposed as what Mersip asked with a switch pedal. For example, I've created some full choir libraries with different vowel sounds, and with a control pedal you can trigger the A-E-I-O-U choir sounds individually depending on pedal position. But for more than let's say 3 different sounds it becomes very tricky to control, since most pedals like the Korg SP-2 have a quite limited movement angle (maybe 30 degrees ?). An expression pedal as on a Hammond B3 or C3 console would work much better, supposing it would transmit MIDI, since it can move more around 60 degrees.

[thethirdapple]

Right, I see now that I mistook the ask as “create a switch action” as opposed to how to alternately “wire” an existing foot switch. Doh! It’s in the title!!!


Have been working my way up the “family tree” of
KARMA enabled synths and various versions of the software for creating custom GE’s. Had a blast cataloging most of the SysEx for the og workstation and created a few interesting combis and tutorials myself.

Overall and in details, KARMA is a wonderfully amazing “sandbox” of musical creations. As I catch up on 20 years of missing out, I can only say that ALL the referenced and created tutorials have been super beneficial, Thank you

Just a confirmation of sorts and a suggestion... which is not yet an on-board solution!

Yes, confirmed that the routing or wiring up of AMS with the FootSwitch is limited and being that the OG poster, is already using both the FOOT/EXP options I would SUGGEST, similar to voip's suggestion:

Get an inexpensive midi enabled pedal which can be more easily wired thru CC#'s and or SysEx to control aspects of the synth and or Karma with more flexibility than the "hard-wired" AMS options which KORG implemented.

I also started down the road of creating a GE which simply attenuates the "Velocity" value of data being sent to the timbre, while a switch is activated. Essentially turning a Karma Module on and off with the "thru" method to affect the timbre with alternatives to AMS!


Reading too much Bertrand Russell:
"sets of sets which include all sets which don't include an infinite set of singleton sets of logical paradoxes..."

IF this yields anything fun, will share a possible solution.

Greetings,

As a follow up, here is an archived thread from MPN, which also laments the difficulty in assigning multiple functions to the on board pedal inputs:

https://forums.musicplayer.com/topic/13 ... s/page/17/

And so it would seem that there are no options to achieve this with the FOOTSWITCH input directly. And with no fault or blame towards any manufacturer, especially KORG, others have recently chimed in with some historical reality that many of such things have been suggested to KORG through the years...

... I fought for a number of years to get that changed, but it didn't happen during my tenure there. I figured out how to make the pedal more versatile by setting it to Knob 8 in Global, since Knob 8 is always used to control Reverb Depth, something I don't need to do when playing live. But since it's a single consistent behavior it is easily re-purposed for other things. So I would always un-assign the AMS setting for modulating the Reverb Depth, and then I could use it most often to modulate volume (actually Expression), and then other times I could assign it sweep the Wah-wah for Clavinet and other useful things...

Utility GE

Sometimes, being simple and useful is super sexy. As I have been learning the KARMA platform I have also been immersing myself with old gear and methods for midi processing. And like so much lately, it struck me as odd to not have some basic utilities written as a KARMA GE.

This project is the genesis of an online prompt in an attempt to route the FOOT-SWITCH pedal as a “volume control toggle switch” for a timbre, using the AMS to an effect routing option simply does not perform as desired… and although the initial ask was/is regarding a KRONOS the method of building a GE remains nearly the same as with the og KARMA WS… soooo

Using KARMA MW, this is a 10-15 minute build from scratch and will introduce how to wire the RTP Controls to Velocity processing. And a “hidden” feature I still can not find mention of, either on the KLF or documentation!!!

REALTIME CONTROL and perfect synchronicity of midi processing. By using a GE module to control Velocity, the FOOT-SWITCH can now affect the volume(midi velocity) of a timbre(midi channel) simply by toggling(switching) the module status “on or off” in realtime without missing a performance beat.
