anyone sucessfully sends CV from Reaper (or other)?
i installed silent way from expert sleepers in order to send CV from an output from my my soundcard, but the results are very bad or i don't understand the results (i get not interesting noise). My soundcard is at the moment RME Babyface on a mac book pro 10.9.5 OSX.
Does anyone happily sending CV from Reaper or any other DAW? Anytips how can i might achieve that?
Thank you all!

i've used silent way in reaper to send CV through the headphone output of my RME Digiface. It's important to use a DC-coupled output, i think. Are you using the headphone output? I've got a suspicion that most if not all of the RME stuff has DC-coupled headphone outs, but i'm not sure about the line outs.

there's also VCV Rack - that has been easy to set up to send CV from the digiface, though i've only used up to v0.5 - standalone, not a plugin

I hate to ask, but what are you expecting?
CV is not audio. I would expect it to sound like random pops and clicks, like when I accidentally routed a raw ADSR envelope to the audio output instead of using it to control an oscillator.

I was expecting CV going from my Soundcard Hardware output into my new Analog Synth : P
since i heard some people with RME and silent way could achieve this!
Thanks!

Thanks for the input domzy! I did not try with phones before but i tried now but no good results.
Still i'll have to try 1 more time later just in case i might be doing something wrong reaper config and RME Total Mix .

have you got your CV and gate signals the right way round?
Have you run the calibration in Silent way?
these are two obvious things that spring to mind but i'm not at my studio at the moment

i bought moog minitaur. It has CV input for Pitch, Volume and gate. I tried sending an audio track with silent way as fx and outputing to phones which goes into moog minitaur Volume CV input. My soundcard as just 4 outputs. i am not sure if i will able to try with more than 1 CV output. Will try this later.
I don't see any calibration tool in silent way, this is what the demo looks like here:
Thank you so much.

Hi
i am planning to purchase the expert sleeper modules to send cv to my modular gear as well.
Please do let us know if you succeed in doing so !
regards

Thanks!

In my most normal scenario i send two signals to my synth - CV which would control pitch & gate, which is basically on/off. I use a Y-lead from the headphone out so one channel is CV and the other channel is gate, but you need to have a suitable output and i don't think the babyface has one.

hope so! alternatively and in future seems ES-3 might work too! didn't know about this hardware units until today. They are expensive (i think) eurorack module. It's a pity it's not available as a usb thing or firewire). Anyway! wonder if anyone tried them!

If you do have access to DC coupled outs, be aware that you need to do the following -
1. Ensure that multiple mono outs are created from the plug in
2. Create hardware sends from that track to the interface, ensuring that you select those MONO outputs as the source.
3. With the multi output plug ins, you will need to create a multichannel routing to get all those mono outs appearing individually in the drop down for the output source.

Really "new" ?
Nowadays it seems rather silly to create / sell a device lacking USB input.
(In the company I work for we build a lot of small devices and providing USB needs additional cost from close to zero to some $10 in hardware, as modern microprocessor chips already provide the complete USB hardware - and analog I/O - and come with the appropriate software to easily make use of it).

Well for one thing the resolution of cv generated by a sound card is limited by its DAC (16/24 bits) while the resolution of a midi message is limited to 7 bits by the MIDI protocol. Sure you can use pairs of CCs or NRPNs but those are really inelegant solutions in my experience.

Both not really true.
The midi resolution can be 16324 (14 Bit) with e.g. high resolution CC (which is supported by Reaper and hence maybe not "elegant" but "standard", and additional bytes don't harm via USB). E.g. ReaRack does use high resolution CC.
The D/A with (cheap) Microprocessor chips is usually done by PWM hardware, so if you don't need too high final signal frequency, you can get rather high resolution.

Interesting! this unit (moog minitaur) has usb for midi, CV ins are just complementary!

I'm running two ES-3's and an ES-5 gate expander from the ADAT outputs of my Fireface UFX with my 5U modular using Silent Way in REAPER and it works flawlessly. You have to make sure your gains and faders pass the Silent Way signals to the modules with no gain or attenuation (make sure all faders are at 0dB in both REAPER and TotalMix) or it won't work properly.
This is my modular as it is currently....
