No worries. Thanks for posting it now.
I'm very excited about this one in particular. I've been waiting for this for a looong time and I really want to dive into the possibilities it offers. Especially the fact that the code will be open sourced means I can probably add functionality that I find crucial, although I'm hoping Befaco will have nailed it from the start.

As you can imagine I'm as excited as it gets, but it seems they are no longer available on your site - that or I'm too early, like the people waiting outside the store to open. :mrgreen:

"There is 1 error. This product is no longer available."

Come on Befaco! :hyper: :hyper: :hyper:

Also, should we email you about questions and/or corrections on the documentation?



EDIT

Got one! :banana: Fast shipping option selected, here we go!

Seems pretty cool. Would love to tie the room together with a Cirklon. But can't my hands on those. This is not as comprehensive as the previously mentioned Cirklon, but realistically, could I build a track with my ER-101/ER-102 combo + VCMC + a few synths? Or would the VCMC be just enough for one synth at a time?

Ordered! :yay: I think this will really tie together my studio, performance wise, since I can control both CC and CV from one surface. Now I need to look for some nice faders and joysticks and LFOs to hook into this beaut!

I know this was just released but hoping a few folks have started using it as I am interested in their experience with how the unit is tracking V/Oct to MIDI notes.

My unit and another user have experienced the unit not tracking correctly as well as inconsistencies in the calibration procedure detailed in the user manual compared to the directions at the end of the assembly instructions for the DIY build.

Any input for other users would be greatly appreciated as Befaco has gone silent since my last email to them :hmm:

I'm looking forward to this.

Can VCMC translate slewed 1v/oct signal into MIDI note and pitch bend combo ?
Or should I use additional VCMC channel to generate pitch bend message ?

Only just starting playing around with it, but so far, it works perfectly. I am able to send it fast streams of data in a way the doepfer alternative simply couldn't handle. The implementation - where you can adjust the voltage range, attenuation, and offset per channel - is suburb. It could use more presets, but honestly, its so easy to program I just spend 2 minutes doing it at the start of a session and am away. I just wish it had a silver panel...

The issues I was having with getting accurate v/oct to midi note tracking was resolved with increasing the CV delay setting to around 8ms :party:

FWIW, I just built a VCMC as a DIY kit, and it wasn't as difficult as the documentation suggested. Granted, the way the Teensy is mounted on the PCB requires you to be careful, but once past that, it's a breeze, and a lot easier than some of the (dense) Befaco builds I did before.
What is especially nice with this kit, is that the building instructions make you test the module as you're building, rather than have you put everything together, and then find out you missed a solder spot somewhere deep down.
Very recommended!

It can't. You need to dedicate one channel to Pitch Bend to achieve that.

Does anyone know the correct settings of in/out range to get 1v per octave cv working correctly? I find that if I feed it a wide range of notes it automatically pushes everything out of a certain range to 0v, and I can't tell why...

Have you set your incoming CV values correctly? Any chance you're feeding it negative voltages but have the setting to +5V as the incoming range? Stupid question, but you never know.

I would like to double check what the incoming range should be. I have tested it various sources, both +/- and +, and all three voltage range options, but I still seem to be getting regular returns to 0v. Can you talk me through your set up when it works for you?

Yeah, I'll give it a shot later today. So your request would be to have a 1V and a 2V both fire C notes, right?

It's more to do with matching the overall range - if I send it a stream of cv values, it interprets anything outside of a certain (quite small) range as 0v. So I am presuming that the range/trim settings are wrong, or its not calibrated properly, or something. If you try running a S+H into the cv input of a channel, is it able to convert everything (or even most) into a note value? Or does your unit convert some notes, but half the time just revert to 0v?

Does anyone know if this will map CV to Midi channel aftertouch messages? Wondering if this can be used with a Vermona Perfourmer MKII to control the filter cutoff. Thanks.

Sorry for the late reply. I get both 5V and 10V working correctly with no 'clipping'. Maybe it's a calibration issue?

Does Befaco team have contact form?
I cannot find it on their website.
I have some problems on my DIY VCMC, so I want to ask about them.
