Linked Knobs - has Preset Manager problem

[RJHollins]

This is so confusing to me

I have assembled an example module that contains 2 Knobs that can be optionally LINK.

For a specific project, the Knobs link in a 'counter-motion' mode [as one goes UP, the other goes down]. OK, no problem there

Then I place a 'PreSet Manager' into the mix.

If I have the link mode active, the recall from the Manager gets all screwed up.

Things seem fine if the link mode is OFF ... but this does not meet the program objectives

I have tried many things ... including different Managers ... made no difference.

I'm enclosing the example schematic ... What am I not seeing correctly.

Thanks for any help with this.

hallo mr hollins, i did some similar stuff in my actual project it is working bit different, but works with presetmanager, i adapted it for your needs.

there is also a mastertrigger included which sets the slave to the inverted value of the master when set the knobs to link, but you can delete the mastertrigger if you want to set only when changing one of the knobs...

hallo Mr NuBeat,

I was looking through the module you posted ... this is a very sophisticated design.
It works very well ...

I noticed the 'vector knob' design, but my project is of the bitmap orientation, so ... I looked to do a swap out of the knob component. I added a boolean 'interact' connection to my knob, and hope I could just switch out connections.

Well ... I got it to [sort of] work But my knobs would jump value when release of the mouse button

I need to give this another try to see if I overlooked something obvious, and get my knob working.

Meantime ... Big thanks to at least know that this works.

[RJHollins]

oh ... after several tries ... I've not been able to solve this

I changed out the vector knobs from NuBeats post above for a pair of bitmap knobs.

To that I had to add an 'interact' boolean.

I have successfully broken this.

As it would happen, this is like the last piece to the puzzle for a project ... the brain has returned to 'Mush' status

I've up'd the sample schematic ... disappointed in myself

[RJHollins]

Taking yet another shot at this ... by George, I think he's got it


Early in the testing ... but I think I have the 'transplant' working ... well, at least the bitmap knobs are now talking and interacting the way they should.

The LINK option is also working ... now to test how the Preset Manager responds.

fingers crossed

[RJHollins]

well ... almost

this thing can get complicated real easy

So far we have this mostly working with the bitmap knobs. [which, BTW, have an entirely different 'support' schematic compared to the working vector model].

I'm still tracking down a bug. [or two]. Cycling through the Preset Manager is recalling both positions and the LINK status, but if I come to a 'preset' that the LINK was OFF ... turning the link ON and moving a knob can cause one of the knobs to disappear [so there is some cell tracking error I think].

I have numeric readouts on both knobs, but when LINK-ed, only the knob I move has its display updated. The 'slave' knob moves, but no change in the numeric readout.

Need to get a fresh look at it ... if I start breaking this to badly, I may have to throw myself to the mercy [and hopeful aid of the Guru's].

So close but no cigar

hmm, recognised the disappearing problem too while doing it with bitmapknobs but i think this one should work ok now, i also added a readout including an edit option which means you can edit the value directly at the readout by clicking on it and typ in the value

Just getting back from my jazz gig tonite ... wanted to be sure to post a 'thanks' to NuBeat !!
Had a little bit of time [and energy left] to check out this latest bitmap version. I must say, I was somewhat surprised at how involved this schematic called for in doing both the linking and preset management. My original attempt had been with nearly all 'green' components. I see that the posted bitmap version had some RUBY flavor to it.
My bit of RUBY included the 'guage' module that you [NuBeat] had put together some time back. [something most needed for every project].

Anyway, with what I have left, I've done the initial 'implant' of this linked module into my schematic. I made a few mod's to the graphics portion with knobs and a different Sync button. Things seem to be working well ... the disappearing knob has not happened I did see a recall glitch going through the preset manager ... so I need to do more testing to see if that happens again.

Again ... the more I thought about the actual workings, the more I realized that this is not as simple a concept as it seems. In particular, deciding which knob would be the master to reference too was the first thing.

Ideally ... if I could ever figure the logic ... I may try again to make the design to use a 'relative' reference [much like the VCA fader grouping on a mixer console. That would be very cool ... but maybe this would be something for a possible next update to the project. [if I could figure it out] ... it going to take me some time just to study and hope to understand how this current version works

For now, I'll test out how this integrates ... and am much appreciative for your time in designing this NuBeat. This has really helped me out.

Thank-you !

you are welcome RJ, i really enjoy to solve (or try to solve) interesting and useful ideas, specially when i can need them for myself too, things like this are always a good learning experience for me too and often improves my own projects, for example your linked knob idea improved my own linked knob because in my previous version you could just use one knob to change both values - now you can use both! great !
