Copy A>B /AND/ use presets?

Question

Not sure if this is possible...

I'd like to use A/B like this http://mididesigner.com/through-the-fog/

AND use presets for groups.

So if I have a knob and a slider, they are in the same preset group, and that preset group is just A & B (i.e. there's only 2 presets)... Is there a way to use the A/B copy above if the two control groups are really just one group with 2 "states."

Basically I just want a way to hit a button and copy the presets in slot 1 to slot 2...

Any way to do this?

Comments

Could you explain this question for dummies, please? Obviously if you have an external RECALL button for a preset group, you could copy from preset slot to slot by recalling... also note that recall buttons can be toggle OR momentary, each with quite different uses.

I've got a preset slider with "PS1" and "PS2"
As subcontrols of this slider, I've got a knob (K1) and a slider (S1)

While PS slider is in PS1 I move controls such that K1=10 & S1=10

I then move PS slider to PS2, and the values of K1 and S1 jump to whatever they were/are in PS2.

I want to get the values of PS2 to equal PS1 (i.e. copy A.B just like your drum FX chain example, except I don't have two groups of controls...Just one using presets)

But I can't figure out how to do it because when I move PS, there's no way to "read" the other preset.

I think the only way woudl be to have a "dummy" copy that has the same controls that I would use as a kind of "buffer" that I would apply the copy a/b thing to.

Just figured maybe there was a slicker way to copy group presets (i.e. take values of Ps1 and copy to Ps2 so PS2 could then be modified with a minor tweak).

So if you have a RECALL button on the Preset for Groups knob and its toggle, then all you have to do is shut if OFF and move from PS1 to PS2. Now the values are the same and you are working with the PS1 values and can tweak them before they get stored into PS2 when you move away from it. Then when you move to PS1 you hit recall and the PS1 values come back again. Does this help?

Ha, great minds think alike. If I'm following your description, that's pretty much what I did. Add an explicit recall button that's a toggle. That way I can shuffle one preset to another.

Would you have any interest in writing up an answer here to your own question? It would help other users who struggle with the same question. Unfortunately, our comments here are pretty dense. In other news, and alpha of panel channel is coming today. Thank you!

I'm planning on doing a vid on the entire layout so I'll go into this part in more detail and post a link here.

Great, everything helps!

puzzled bij the article 'through the fog' and this question - as a guitar player, the A > B thing.

Is it possible to duplicate (make similar) two set of amp controls (sysex messages bass, mid, treble, gain, volume, etc) and switch between them? Of course one could create 2 group presets but duplicating controls and activating them with a switch? Like A - B for (example) each global preset?

When reading the article and watching the video it may be possible with a crossfader and crossfade overlap functionality. Maybe it is an idea to assign the A> B functionality to a configurable toggle or momentary button.

Well, this is a bit odd question, partly triggered to have some sort of visual A - B amp.
That would mean to have to 2 sets of similar knobs, adressing the same sysex, but turning on/off in predefined state with a button.
Is preset the only option for this? Then one set of knobs goes out the window and it is standard preset 1-2, A-B.

You've seen this thing, right?

@Gurbz the A-B thing JUST copies values from one set of controls to another. There is no way to shut some controls OFF, though using a channel changer you could put one set of subcontrols into an unusable state while other subs go in to a usable state. Does that make sense?

Comment 1:I ‘ll read it again.
Comment 2: channelswitch?! Interesting! Never used that. Is there a question:topic in the Q&A that looks like this? Of course I’m gonna google it but its always nice to have a start. Thanks for your comments. MDP2 is easily the app I use most. It ‘s the new ticket to expression for guitar players. The A>B principle must be attracting for guitar player, a lot of multi fx work that way, 2 sounds a patch, dry and wet, backing and solo, etc

So: I have for example 5 knobs with sysex messages (bass, mid, treble, gain, volume) and I make a similar set of controls like I have a preamp A and a preamp B. Both sets of controls adress the same sysex so what happens when I use a channel switcher then? Midi channel 1 and 2?

---

The Channel Changer can alter one of the bytes of the controls (the one that you sub for L, I think). This has nothing to do with A/B functionality, but this would allow you to switch from one set of active controls to another. I think you should break out your question, simplify it, and make it a proper question on the QA forums with a focus on what you're trying to do . That way we could discuss there?

Thx for the kind words and entusiasm as always!
