OSC-to-CV output?

August 11, 2008 | 9:55 pm

Hi all,

I am looking for a solution that would help me eliminate midi-to-cv
conversion from my rig. In fact, if I could get rid of midi here
altogether that would be fantastic!

OSC-to-CV is what I need. high resolution, like 12-bit and above is
preferred. This would really let maxMSP shine for me.

Is there anything like this? Loads of sensor boxes take analogue INPUTS,
or stuff like the gluion is really only digital out… The sensorwiki is
pretty barron on the output part.

Any takers?

Have you looked into IpsonLab?

There is also the Smart Controller stuff

I haven’t found anything that meets the specs I want exactly, so I was thinking about designing a 16-channel 16-bit OSC to voltage converter.

I would be interested in that. I would buy one in a heartbeat.

If you lowpass filter a digital, PWM output you can get analog voltage.

DOH, forgot about those! Thank you, I will get in touch with them – it
looks like a 1-day project for a decent solderer. Gotta love that ol’ OSC!

Not high enough resolution on the outputs, i’m afraid. It seems a bit
underspec’ed, really.

I too would buy that in a heartbeat – make that pcb small, so that it
could be mounted in modulars!

I’d second that – definitely would buy several units.

Cool, I’ll start a post when I get to working on it. Right now I have a couple other hardware projects I need to finish first so I can get some development funds.

I’ve been doing a lot of Ethernet hardware at work, so getting this done is becoming increasingly likely.

My only real problem right now is the software side. I can setup the hardware… RJ45, PHY, MAC… but then I don’t know how to handle a TCP/IP stack on a microcontroller.

I can find plenty of articles on what TCP/IP, UDP, and other various acronyms mean, but I really need a simple breakdown of how to do all the encoding/decoding from scratch. Does anyone have any tips there?
