hello,
I'm trying to convert poly cv into mono,
is there a way to do that ?

If you're working with Player REs this one has a switch on the back to go from poly to mono CV out: https://www.reasonstudios.com/shop/rack ... converter/
Yea, but it won't change any Poly CV coming into it to Mono CV because the switch is for "CV OUT" from the MIDI input (not the CV input). And if you hook two together, you get mono gate CV with poly note because you need some rules to define which note to play (highest, lowest, last).MannequinRaces wrote: ↑08 Jul 2020If you're working with Player REs this one has a switch on the back to go from poly to mono CV out: https://www.reasonstudios.com/shop/rack ... converter/
What you need is Distributer (free: https://www.reasonstudios.com/shop/rack ... stributor/) and set it to 1 voice (it defaults to 8) or set to "Auto".

I think this might be the RE you're looking for: https://www.reasonstudios.com/shop/rack ... akout-box/

thank you for your replies
none of these solutions works for me
Distributor seems to cut held notes in segments
and the two others kill the signal
actually I'm trying to redo this

but without the held notes problem
any idea ?

I'm confused - there is no poly CV in that example. Peff doesn't mention poly at all, except to say polyphonic sources won't work. "Poly CV" means a very specific thing in Reason, could be this is the source of confusion?jeanine wrote: ↑13 Jul 2020thank you for your replies

Maybe let's start over with a description of exactly what you're trying to do. Could be converting "poly CV to mono" is not an accurate description of what you want?

ok
the idea is to record in the sequencer the midi notes detected by neptune (convert on the fly vocal into midi )
there is two CV outputs on the neptune Pitch and Amplitude
pitch work fine if you convert the CV in unipolar
but the gate reacts strangely, notes have an infinite length (each note is triggered well but hold until there is no more sound in the mic)
so I'm trying to convert this CV gate in mono to have a clearer midi recording
but maybe the problem is somewhere else ?
If anyone wants to try :
- create audiotrack (connected to your mic)
- add neptune on it
- mute track, enable monitoring
- flip the rack, connect PITCH CV OUT to something that convert bipolar to unipolar (ex https://www.reasonstudios.com/shop/rack ... -analyzer/)
- connect AMPLITUDE to a combinator Gate In and the converted cv to CV In
- in this combi create a synth in mono and a Scales & Chords player with "direct record" on, and "Chords" off
- be sure to record on you synth track (not the combinator one, I don't know why)
- try your voice in the mic
otherwise, peff made a file almost ready to use here http://www.peff.com/record/downloads/pe ... cvgate.zip

Oh I see - latency will still be a problem, and any bleed into the mic from the PA etc will make things even more difficult for the pitch to CV conversion. I would have to work with the setup myself before I could give more useful feedback, as I'm not exactly sure what the gate problem is and how it could be mitigated.

I am working on a solution to a nearly identical problem. This subject is what brings me to the forum for my first comment. Today, I hope there is continued interest in this subject, though it is now December, and the last post in this thread was in July of this year. It is an ongoing interest for me.
Like jeanine, I am using Neptune (with some upstream gating and filtering) to pick-out the bass note from an electric-acoustic guitar. I am following a method shared by Peff...
http://www.peff.com/journal/2010/08/25/ ... ate-combi/
...to accomplish the task. It uses Thor to properly condition (i)Neptune's note information for ingestion by other devices' "note" inputs. The end result is that we get a very nice bass accompaniment effect, driven by the lowest notes played on a guitar like the one I purchased for a daughter learning to play. I like the effect. It makes playing the guitar much more engaging. When layered with some processing of the raw guitar itself, the additional bass provides a lushness to the sound, which I find drives creativity. And it puts one closer to the objective of rudimentary, on-the-fly / real-time accompaniment.
So, yes, we are able to get approximately what we are after in this thread, in the sense that it is good for OTF / RT performance, as long as the instrument (e.g. Sub) that is chosen to voice the extracted "note" is forced to monophonic. That part is working well enough. Internally, the stock devices are doing exactly what we want them to do with incoming notes, when polyphony is set to "1." They are playing the last note - and only that note. That's half the objective.
Unfortunately, however, as you have explained, jeanine, solutions like yours or my implementation of the Peff solution are not quite suitable for recording MIDI data or for driving, say, an A-list Guitarist strumming in the background along with a live jam owing to what remains in the CV signal stream. The root cause is as Selig has observed. In my case, there are incidental, incorrect notes briefly detected by the Neptune, and these remain active, along with the persistent, correct bass note that we're after, until the input to the Neptune goes silent. And no mashup of rack devices, no hack that I've tried so far has been able to deal with it completely. Dang.
If only there were a way to optionally enforce monophonic note and gate output on Neptune, things would be well and good. A bit more sensible too, I think. Alternatively, if there were "note" and "gate" outputs on the stock devices, mirroring the same polyphony settings as selected on the front panels, that would make short work of this. But no. Again, Dang...
There is still hope that we can hammer this out. I've not given up. Others may have it worked-out, as far as I know. I have, for example, the Delta MIDI Computer device from Static Cling...
https://www.reasonstudios.com/shop/rack ... -computer/
...and it should contain what we need to get the job done. I don't know whether it does or not, as I have not yet become proficient in its use. If I am able to beat this problem into submission one way or another, I will post a solution. In the mean time, if anyone on this forum has already solved it (my expectations are modest, based on what I've read here and elsewhere), and if they are willing to point us in the right direction, with attention to the specific objective, please do share. I will celebrate it! Or if there is a RE that does the trick, please do let us know. By any means, it will be enabling to learn how to accomplish the mono-CV out (last note played) effect that we are after. Short of purchasing a solution like OMB, I think we should be able to solve this in Reason.
