Help with Kurzweil K2700 FXMODS

[ReCoop]

Hi all -

I’m trying to tweak the delay effect in a program (which is then used in a multi). The program is 839 TremBucker, and I tracked down the delay effect to where it was hidden, combined with a Chorus (in box 6 of the insert effect). The FXMODS for box 6 include Ctl A and Ctl C. What are these? I can’t find them in the manual or in the PARAMS.

Any help appreciated. If I understand Ctl A etc. I may be a step closer to doing the tweak I want. But only one step…

I'm not in a position to check on my K2700 at the moment but I suspect that "Ctl" in this case refers to one of the 9 physical knobs and/or sliders marked "Control" on the left of the synth.

You can check this easily enough by moving A and C to see if they affect the sound. Alternatively when a "Source" field is selected on the page listing the FX Mods, if you hold the Enter button down and move a physical control then it'll assign that controller as the source in question, so you can see what the K2700 calls those knobs and sliders by doing that.

Ctl A-D are actually 'General Purpose' MIDI CCs 16-19. If you scroll through the modulation source options you will find them listed in sequence between CC 15 and CC 20.

Thx for the pointers - keyboard is packed up for a rehearsal this evening but I’ll check the Ctls asap and probably have a further question.

(Since I posted, I’ve found a sound posted by someone on ksetlist for the song I want - Let’s Dance by David Bowie - so maybe that will solve my problem if I can load it).

So I had a look in my K2700, and by holding Enter and moving various physical controllers I tracked down Ctl B, C and also E and H. There’s a table on P3-7 of the manual which is supposed to list physical controller CC numbers and 16 to 18 are Pad 1, knob 6 and knob 7. The knobs I can verify by moving them (and they work as per the FX setup) but Pad 1 makes no sense, and does not do (in the effect mod setup) what it is supposed to do.

It would be nice if the table in the manual actually identified Ctl B, C etc. alongside those MIDI CC numbers .

Right now I don’t even know what question to ask for clarification! Thanks for your help so far. I will go back to the manual (including one on the Mastering VAST forum) and see if light dawns. I think I need to understand the connection between PARAMS and FXMODs.

“Params” is a sort of master list of all the physical controls and where they’re pointed. That includes all the ones in the program (e.g. assigned within synthesis) AND all the ones within the effects chains (the FX MOD controls you see on the pages Mod1 to 3). E.g. Vibrato - ModWheel” (synthesis control) “INS Chorus Depth - Slider 8”. (Insert effects chain control).

I only use the PARAMS list as an overview, I dont do any assigning there; I always assign a controller in the relevant place (whether in synthesis blocks or in effects chains).

So, assign your chosen control on the Mod pages inside the effects chain. When you exit/save, the control will automatically appear on the PARAMS list.

In the Multi, when you bring your new program in, you might need to hook up your chosen slider to itself. (If the controls were already hooked up on every zone it would be mayhem).

This is where the power of MultiMode comes in. On the Controls page you can assign any control to any destination, so you could chose to use, say, the ModWheel to bring in your delay effect. (i.e: if in the program you were using Slider 7 [cc26] then you would assign the ModWheel to cc26).

You could also assign a foot pedal to do the same thing. (In this example just assign it to cc26).

As a new owner of this keyboard, it is a nightmare to get to grips with. I was saying this to a bandmate last night and he asked me if I'd researched this before buying. I said I'd researched what it could do - basically everything - but not how easy it was to persuade it to do those things

[ReCoop]

Thanks Enjoy Malc, I’m getting to grips with those arrangements. I’ve successfully assigned various physical controllers in programs and multis but sometimes in the factory ones I can’t tell where some of them come from and go to! Particularly when I don’t want them, rather than do want them. I wonder whether some mappings are “legacy” from other Kurzweil keyboards and are actually redundant in the current programs?

Bonefixer - I commiserate, but in my case I definitely was prepared for it to be difficult, with the upside being the complete configurability. During band rehearsals I’m now finding it really easy to tweak the multis I’ve created for all the songs, as I get experience using them.
