MidiBox CV as a Midi to CV unit

It was easy peasy soldering the TLV chip. I wouldn't like fewer bits for my pitch CVs, and the MAX525 is expensive, plus the shunt required is a component sourcing headache I don't need. I fail to see any valid reason to go with a lesser solution than the NG, and the MBHP_AOUT is expensive and harder to source for a marginal improvement.
I got my AOUT_NG in the kit form from Smash-TV so I avoided any sourcing. That said, there's nothing strange in there so it should be smooth sailing no matter what.

Definitely. Since you can't ever have enough, you can obviously never have too many.
My 2 cents as I'm using the AOUT_NG connected to my MB-SEQv4 in my modular: You can never have too many CV out channels!

I did my first surface mount board last week and it was much easier than expected. I ended up bridging a few pins, but solder wick fixed that. Give it a go - it isn't as scary as you think!

I've got all the parts on the board except the 7805 Regulator, the BC337 transistor and the two IC's. I also held off on mounting the large IC socket for the time being because, I see a couple of unmarked holes on the board and I was wondering if I needed to run some jumpers in them spots. The board I have is the latest Revision 4d board. On the uCapps site there is a walkthrough for the older revision 3 board, and in it there are 4 jumpers that need to be soldered in but so far, i've found no mention about any jumpers for this R4d board. Do I need to run any jumpers on this board?
Also, my kit came with an extra 1K resistor and an extra 1N4148 diode for the "CAN bus termination". I did a search for the CAN bus termination on the wiki and stuff but, I can't tell where or what it is except that CAN stands for Controller Area Network and, if i'm not mistaken, has something to do with the SID module. So you know, I got my board from AVI Showtech and there is nothing on their site about where this CAN thing is and, it so happens, there's no mention about running jumpers on their site either. Either in writing or, in pictures.
Lastly, the walkthrough I mentioned earlier for the revision 3 board has some testing procedures for that board. Basically, aplying power to the board and reading the voltages at a few pins on the IC sockets. Is there anything comparable to the R4d board out there or, should I just follow the same procedure for the R4 board?
