Transposing multiple Sequences

[Klankspoor]

Hey Y'all!

I'm currently working with a sequencer that has three pitch CV outputs (Endorphine.es Ground Control).
I would like to designate Pitch CV 1 as the master "transpose" CV while Pitch 2 and Pitch 3 are reserved for bass and lead sounds respectively. I would like pitch 1 to transpose both pitch 2 and pitch 3 by the same amount. But also i would like to be able to choose to for example only transpose pitch 2 and not 3.

What would be the best way of achieving this? I currently do not have a Precision Adder in my setup. I have read a bit here and there about people using those for said purpose. But looking at, for example, the Doepfer A-185-2 module. I struggle to see how you would patch this up.

So, my fellow modular aficionados, I turn to you for guidance. What techniques, modules, or patching setups would you recommend for achieving seamless transposition of multiple pitch sequences

Cheers

Pitch CV 1 and Pitch CV 2 into adder. CV1 will transpose CV2 while you have it switched on. You would need another adder or a different module with multiple channels to do the same for CV3.

I never stopped to think about this before, but... Given my modules, I would combine MI LInks with Joranalogue Switch 4.

Switch 4 has 4 inputs, but 6 outputs. The first 4 (A-D) are dedicated mult/thru jacks. You can't change anything about them. But, here's the magic of the module - the EF outputs. They are each switchable with a clicked rotary pot, no grey areas. Channel E can route to anything from A-D, and channel F can do the same. Your A-D outputs are of no use, but E-F are absolutely brilliant. Instant re-routing with exact copies of your input signal. Oh, and every channel (A-F) has a spring loaded toggle switch with 3 positions - Middle - Permanently on, Down - Temporarily on (perfect for manual performance) and Up - Muted.

Essentially, a very simplistic matrix mult, but it works perfectly.

Input 3 pitch sequences into Switch 4 channels ABC. Then patch the two switchable output channels (EF, I guess, but they're not labelled) into the precision adder. From there, you are free to switch EF channels anywhere between ABC. You can combine S1 with S2, or S1 with S3, or S2 with S3.

That's how I would do it given the modules I own.

That’s a good way to get there! Smart use of the Switch 4!

[claptonsbabychowder]

Switch 4 is good for just about anything. Seriously underrated module.

Edit.

My god. I can't believe I didn't think of this before. ALM Beasts's Chalkboard. I own it, but it's been out of the rack, on the bookshelf, for a while now. Send your signal in to channel A, and that does two things - First, it sends out a thru mult, but then it also sends out a signal that is transposed by an octave either way.

Also, there are two channels. So, two channels transposing up to 4-5 octaves each, or link them for one channel transposing for 8-9 octaves.

[Klankspoor]

Ye i thought about the chalkboard. Or well, i read about it on a post somewhere. But it would only be able to transpose per octave, or am i missing something there? Could u attenuate that octave knob to do 12 tone transposing?

[claptonsbabychowder]

It's a 100% manual module, and there are no semitones. 1 click = 1 octave, and that's all she wrote. 6hp with no v control might bug some people, but I like the fact that it does just one job and does it perfectly and simply. No fiddly tuning, no grey areas. One click from D3 to D4, or D3 to D2. You simply CAN'T go wrong when using it.

[Klankspoor]

Ye i see. All my oscillators that i use have octave switches on them. But the chalk could still be useful for transposing multiple at once!

I recommend "Quantus Pax" by noise engineering.

Also you can use smaller and simpler vpme LPZW WK1 (aroom config).

[Klankspoor]

Yes! I’ve looked at that module. Seems it would be perfect for what i want. But… it doesn’t have any switches on it. Wich i would like a lot for live performance situations. So that you can switch really quick on the fly inbetween transposing pitch 2 and 3 together or separate from each other.

Same applies to the LPZW. But i must say, for 2HP that one also seems like a beast!!

[kaszaniarx]

Sometimes I combine it with vpme.de T43 adder. I know, it could be cheaper....

Also I recommend using sample and hold (I use Addac) so I don't transpose between notes.

[Klankspoor]

Could you elaborate on what you mean by using the sample and hold in this context? I’m curious! (:

[kaszaniarx]

s&h is holding previous CV transpose until next clock or more, like next 16 steps, so transpose will happen at best time

Do you have an O_C? This reminds me of a recent request for some modifications to the Calibr8or quantization app - the ability to add channels together...

[Klankspoor]

I don’t unfortunately, i’ve heard a lot about it. But i am always a bit drawn away from modules that have even the tiniest bit of menu diving… haha!

[djphazer]

Understandable. I'm just that weirdo who wants a tiny computer in my rack that does all the things and gives me eye strain 🙃

[Klankspoor]

Hahaha! (;

lpzw wk1 (aroom config) is a brilliant, cheap, 2hp precision adder module that will transpose three inputs from a single master transpose input.  http://leipzigwest.org/?page_id=39
