My issues with CV/Gate Expanders

[Renzki]

Thanks Thomas and Michael

From your responses, it seems obvious that the problem comes from myself. I apologise for having wasted a bit of your time.

Michael, would you be able to guide me towards a place where you can download some projects or just patterns that are pre configured that would illustrate your explainations?

That would be of great help. (I'm terrible with abstract)

Cheers guys.

Hi Renki,

not sure it is you...

A while ago I tried to do Bach's Brandenburg Concerto No.3 with the NerdSEQ. Just to see if it would be possible (it is )
There are older versions that still should be valid found on this forum. You'll find them under
https://xor-electronics.com/forum/showth...p?tid=1280

The current version of those projects has some minor tweaks regarding articulations as well as fixed a few wrong notes here and there. I've also changed the notes such that they now go from 0-10 V (instead of -5 - +5 as in the above thread).

I suggest you look at those projects. Feel free to ask questions. If there's interest I'm happy to add the current updated files as well.

Kind regards,
Michael

I not a fan of JSB, even though they tried to feed it to us from kindergarten, I remain a punk that blasts ultra loud live tekno at illegal rave parties.

However, I must say that those who created synthesizers would be really impressed with your work as that's basically why they created them in the first place (not for tekno punks for sure). This must have taken you a tremendous amout of pragmatic work to make this happen, all my respect sir.

Tomorrow I will try your files and will go though thourough analysis and will get back here eventually if I have any questions.

PS: For better clarity drawing diagrams, I suggest draw.io

Dear Michael,

I opened your project and had a close look at how it's made. I noted that it's assigned to 2x of More CV Expander.

I did not see much more than what is seen on your video, being one lane for notes and one lane for envelopes (modulator)

So far, I am still struggling in finding what I was asking about, being assignation of various commands on a note.

If I want one note to be:

- filtered at 30% on Erica VCF (1CV)
- resonnating at 73% on same mod (1CV)
- reciving the effect number 6 FX mod (1CV)
- effect 6 to be at 8% of parameter 1 and 56% of parameter 2 (2CV)
- diven at 60% on the Pico drive (1CV)
- CV amount of VCA on mixer at 60% (1CV)

That's a total of 7 CV outs on this example. Is this delusional or is it possible, let's say, if the channel (or lane) is assigned on the CV expander.

Thanks

Possible:
I assume you need also the note and a gate which would make it 9 settings.
They are 2 possibilities for that.
Column 1: Note
Column 2: Gate control
Column 3: Erica VCF
Column 4: Resonance
Column 5: 6 FX
Column 6: That parameter 1 thing
Fx1: Parameter 2
Fx2: Pico drive
Fx3: VCA
All onto their own CV output and all from only one track.

Or you can use the patches and set your preset settings with that (or even more outputs if that is not enough)
Leaves you still 7 tracks to play around with and a couple of CV16 outputs that you also still can use.

Well, you have 6 lanes (CV columns) and 3 more FX columns for which you can change the value with every step. When the CV you control from the FX columns are not supposed to change with every step then you can emit even more CV by interleaving them on the FX column (though then changes in FX values aren't strictly in sync with the other stuff).

W/o really fully understanding what you wish to do I'd say it should be possible.

Note that this assumes all of your 7 CV as of your example above are completely non related to each other. Otherwise you could save on CV (but you figured that yourself already )

Doing all this programming will require quite some work though but it should be possible.

W/r to draw.io:
I did not draw the diagrams and I certainly would not want to.
They were created programmatically. I just described the patch in the text form and the graph was then created. The text file is part of the stuff I uploaded.
The text file is basically what I write down for myself when I take notes. Bringing it into a format that can then be automatically converted into a graph is very little additional work.

Kind regards,
Michael
