jonbstevens Posted September 18, 2012 Report Share Posted September 18, 2012 Hi, I just wanted to say thanks, I built a MidiBox CV over the weekend with Core, DINx4, and Aout NG kits from Smash TV, and powered by a MFOS wallwart bi-polar power supply. It works great controlling my modular synth, I get about 6 octaves in tune from my MFOS VCO's, and the sync output is really nice to drive a CGS Programmer/Sequencer I just finished last week. Thanks for making this project available! Quote Link to comment Share on other sites More sharing options...
gslug Posted September 19, 2012 Report Share Posted September 19, 2012 Congrats! :sorcerer: Spooky timing as I have also been building a MIDIbox CV today. Mine isn't finished yet though. Quote Link to comment Share on other sites More sharing options...
daemonik Posted September 19, 2012 Report Share Posted September 19, 2012 Congrats! :thumbsup: I love the MIDIBOX CV too, considering building another one/two... I also tried to power it with a MFOS wallwart bi-polar power supply but had considerable errors with it! The device didn't power up properly every while and then. That happend in general when turning on shortly (<10sec) after turning the suppy off. It showed, that the positive supply (core + aout_ng) had a slightly negative voltage. I've changed to a unipolar supply since I didn't need bipolar for my current setup... but with a DIY modular as future-project I'll get back to this issue. No problems with yout power supply?

shimoda Posted September 19, 2012 Report Share Posted September 19, 2012 Curious about this, can the Core8 be used for a MidiCV? More specifically, can it be used with the larger NG module? I now have the mutable Anushri which takes CV so it would be nice to have something like this. Quote Link to comment Share on other sites More sharing options...
sneakthief Posted September 19, 2012 Report Share Posted September 19, 2012 Yes, at the moment the Core8 is the only solution for the non-beta MIDIbox CV version: http://www.ucapps.de/midibox_cv.html Quote Link to comment Share on other sites More sharing options...
analog604 Posted December 6, 2012 Report Share Posted December 6, 2012 (edited) Hi ! I haven't seen too many postings of completed MIDIbox CV builds, got any of your build to share? It is in progress (got sidetracked greatly in 2011 !).. full build progress photo log: Jay's MIDIbox CV build circa 2011 with this recent set containing most recent photos: Dec2012 CV pics It works and calibrated with my bench top variable PSU but I need to get it working with my in-progress modular synth PSU.. almost there. [edit: oh yeah, this frontpanel design was inspired by Sneakthief's work, except that I made it for 5U] -Jay Hi, I just wanted to say thanks, I built a MidiBox CV over the weekend with Core, DINx4, and Aout NG kits from Smash TV, and powered by a MFOS wallwart bi-polar power supply.
