Converting Unipolar CV to Bipolar
Is there any technique or device that can convert a unipolar CV into a bipolar CV? For instance synchronous outputs 0 to +5v, which means it can only modulate up or down from the control value point where as pulsar outputs -5v to 5v and is able to modulate up and down over a control value point. If I'm using a sine shape in synchronous, I'd like it to behave in a bipolar manner.
EDIT: I figured it out, shoulda known Lectric Panda woulda had something for me! Janitor CV Shaper w/ offset and scale did the trick. I knew there was a reason Lectric is my favorite RE dev

It seems that we once answered together in a similar way.

Interesting, I managed to find a solution outside of Reason first.
In preparation for Rack VST but no VST hosting, I wanted to be able to modulate parameters of VSTs w/ the modulators in Reason. I converted Synchronous CV to audio w/ Thor and then Rewired into Bitwig Studio w/ Bidule. Using BWS DC Offset effect into a gain utility and into an oscilloscope I was able to adjust the gain of the signal once offset to produce a similar effect. Then sent that signal to an audio rate modulator and it worked a charm!
I really do appreciate everyone's input, things w/ CV are not always easy to discern.

QUESTION:
Without modification, is there a device in REASON that emits a strictly UNIpolar wave?
NOT a CONVERSION. Not an ENVELOPE.
If not, Offsetting and Scaling is OK and may be Practical, but it's not the best Mathematical approach, if you get my meaning.

In this case do you mean to send Thors Mod Wheel (Unipolar)?
Or do you mean a LFO type mod? In this case https://www.propellerheads.com/shop/rac ... phase-lfo/ has a unipolar switch for the loo (on the back).

The interpretation formulas got me thinking about thor's scaling (in what appears to be a trig function - eg. sine)... I guess this is along the lines in some ways as the ARCUS User Knobs RE (Alien Seeds). Made me wonder if you can use trig function formulas in Remote...
Thors Mod Wheel (Unipolar) is not an LFO. Sorry.
4 Phase LFO is a Good One. Nice.
But - NO.
Switching the 4P LFO to bipolar is more like offsetting it to 5..
Truly unipolar is ZERO to.... whatever.... not a new Center of CV=5/64/whatever.
Nice try, though!
....so.... no Native UNI-Polar LFO....? or, otherwise.... ? Interesting.
....so much for....." Converting Unipolar CV to Bipolar "

Not sure if I'm understanding but Synchronous emits strictly unipolar, and is the reason behind the question of the OP.O1B wrote: ↑28 Aug 2019Thors Mod Wheel (Unipolar) is not an LFO. Sorry.

Not sure if I'm understanding but Synchronous emits strictly unipolar, and is the reason behind the question of the OP.
Synchronous emits a only an INVERTED copy of the CURVE. There is no LFO that I am aware of.
If I'm wrong, I apologize, but - Please, indicate unipolar LFO pls, if you can.
but, if .... "Synchronous emits strictly unipolar [WRONG], and is the reason behind the question of the OP"... then - I'll bow out of this thread.
Lempface, there are a lot of awesome uses for a truly uni to bi-polar switch. FX-wise.
I use a Scaler Polarizer Offseter (SPO) so the effects are not new to me.
- but, FINDING a TRULY UNI- to BIPOLAR CV TOOL would ALSO be quite useful........ for me.

See Mutable Instruments KINKS...
SIGN section ....( the Arches.... Top Section... Bottom Right ... or LEFT, if that's what's needed)
This section consists of a precision signal inverter, and half- and full- wave rectifiers (which respectively clips to 0V, and inverts the negative half of the signal).
They can help in creating new LFO shapes, add overtones to audio signals or even transform CV melodies.

Synchronous does not have an LFO if that is what you were looking for, but it does emit only Unipolar. Standard CV out is 0 to +5v and inverted CV out is 0 to -5v.

But, about the OP...
1. LOAD A SYNCHRONOUS and a SKOPE M4.
First, SEE that without RUNNING the sequencer, there is no WAVE, BI/UNI/Inverted - or, otherwise.
NOW, RUN the SEQUENCER and then... STOP.
What do you see? You see that the SKOPE is stuck on CV=between 0 and 5.
It's really OFFSET at 2.5.., not BIPOLAR, and not RECTIFIED to UNIPOLAR.
2. For PROOF of it being OFFSET and not BIPOLAR nor RECTIFIED to UNIPOLAR:
Load a PULSAR and PASS the SIGNAL through SYNCHRONOUS and INTO LP's SKOPE M4.
You will see that the wave is NOT Bipolar at the 0 crossing, but is BIPOLAR around CV=2.5...
No bueno.
That's just the way it is, I'm afraid. UNIPOLAR seems to MEAN BIPOLAR around CV=2.5
Selig is here. Perhaps he can speak to this phenomena.
I want to go Bi to Uni, Lempface. (I have my reasons)... but try the following to see the results:"Is there any technique or device that can convert a unipolar CV into a bipolar CV?"

I'm guessing that you tried by now, Lempface.
This is what Reason Does, I believe.. but, it's really OFFSET..... less useful.
This is what OP would give us [""Is there any technique or device that can convert a unipolar CV into a bipolar CV?"]
Big up to the first ever Reason Scope, btw. I still cherish it, like a C64.
without it.... we'd be Lost.

So why?
Are you wanting a rectified LFO? Synchronous is unipolar as far as I'm concerned because it does not cross below the 0 point, staying to one pole....

Sorry, Dude... see the image ... INVERTED is TOP RIGHT.
" it does not cross below the 0 point, staying to one pole...."... FALSE
The Top left is PULSAR straight
Bottom Left is CURVE. Top RIGHT is INVERTED.
" it does not cross below the 0 point, staying to one pole...."... FALSE
The Top left is PULSAR straight
Bottom Left is CURVE. Top RIGHT is INVERTED.

From Mutable Instruments...
It's easier to access the reasonings in Eurorack. I can explain my specific, personal uses, if you'd like.

Little LFO by Little IO offers unipolar LFO. I believe it actually generates a wave from true zero. So I can scale the wave’s amplitude and the “floor” is fixed at zero.
We were on about SYNCHRONOUS, Ijekio. Thanks, though.
I hooked up a Pulsar to Thor... CV IN and OUT... other than that, you might want to explain your image.
I don't own that RE, but I suppose I could download it. Is it doing something I should be aware of?
Again, OP was talking about SYNCHRONOUS in our DIALOGUE.

FINALLY! Little LFO by Little IO does do TRUE UNIPOLAR cv...
1/2 way there..... there is no CV IN/THROUGH so we are dependent on it's CV-able WAVES.
Again... we can't use Little IO for the "CONVERTing... as per OP.
now.. can Thor/anything covert UNIPOLAR to BIPOLAR?
Then, the functionality (CONVERT UNI to BI/vice versa) is TRULY in REASON.
NOT... OFFSET, again, pls.. and NOT SCALING.
Nice on on Little IO, Timmy Crowne! We do bet BOTH with Little IO.
