Concept: the LINN [planar2+ style thingy? ]

Hey guys! Here I am with another concept for a new module. Only this time, it isn’t necessarily to fix a problem that might not exist. I love using the planar2+ in polar mode, and taking the xy outs in bipolar mode. Lots of fun. But I have this theoretical patch that involves like six of these chained up together, with buffered multiples in between. Ends up making some chaotic madness, but sounds ** usually ** pretty great when sped up to audio rates. I sketched out a module that would be very simple (just two inputs and a lot of outputs) that could be done in theoretically 8-10 HP.

On the first row, there are two inputs, the cv 1 and 2 on the planar. Then there is a thru output (basically a buff mult of the inputs). After that, there are two pairs of outputs. The first is like the XY output on the Planar. The second is what that XY output would be if you swapped the two cv’s (radius and angle).

On the next row, it internally routes a buffered signal from the first output pair, and treats it like this was now the two inputs. Again, two pairs of XY outs. The other half of this row does the same thing with the second XY outputs, to again provide two pairs of outputs after a polar conversion.

On the next two rows, it does this once more for each of the previous four pairs of outputs with eight outputs here (sorry for such a bad sketch but here it is!)

This is totally not to scale by the way.

So now the question:

  • I would buy this module!
  • I would not buy this module.
  • I don’t understand this module

I basically want to do what I did here with Planars in a way that is much less of a nuisance but the same function…


all cv inputs are set to polar mode.
works great with audio. Patch two simple oscillators in, take all of the outputs and send to a mixer, and you get instant polyphony. it’s amazing. I think. I haven’t actually tried it yet because you can see how much of my intellijel 84hp rack this would theoretically take up.
It would also be expensive. But I would love to see a simple module that can do this by itself, in maybe the same amount of space as one planar and a buff mult. Is that too much to ask?

If anybody has any planar’s lying around, please feel free to try constructing this patch (or even only use a couple) and reply with how the audio sounds before and after please?

So the two vertical cables are the inputs. They are normalled to 5V, although you can switch it to 10V using a jumper on the back. this normalling is important because you can use the two attenuverters to control everything.
Next are the two blank outputs of the buffered multiple—they do what they say. Just a through for the inputs, outputting an unmodified input signal.

Then it would internally do what the first planar is doing, a live polar-to-cartesian conversion. This can take triangle or saw waves and output two sines with some harmonics. This output is the the second buff mult. (XY pair) This is exactly what a planar in polar mode does. But the next part is where it gets interesting.

The last pair of jacks on the top row does the same thing, internally doing a polar conversion. However, this uses the second planar in the patch. You will notice that the two cv inputs swap. Thus, a completely different set of waveforms. These output an XY pair from the third buff mult on the top row.

This is where it gets chaotic. Each of those outputs is internally buff multed, and the process is repeated. The XY position becomes the radius and angle. These output XY pairs which would be taken from the planar xy outs on the bottom row. This totals to 30 outputs.

Edit: In the diagram below, the through outputs are replaced with attenuverters.

So I used some basic picture splicing to show sort of what it would actually look like:


I’m calling it the Linn, another name for a waterfall.
Only the two jacks with attenuverters are inputs.

I hope to use some sample oscilloscopes to show exactly how this works but it could take me quite a while.

So it’s a planar2 in polar mode, but going into another?

This sounds like an interesting concept but please explain it better. The patch is busy but helps a little.
