My plan is to feed real-time brain activity data (EEG) into my Max patch at a rate of around 500Hz (sample size 24bit), and render a few channels of this data into sound. So the incoming data is going to be a rapid stream of numerical values, but what I can't figure out is how to turn it into an MSP signal. I can, for example, use objects like [zl] to scale the data into a range of float values between -1 and 1 just like a wav file. But how do I get it from this kind of numerical state to actual sound?

I guess you could say that what I'm trying to do is something like the inverse of [capture~], but with a continuous stream of values instead of a static text file. It seems like it would be a fairly straightforward process, but I am new to Max, and am having trouble with this. Can anybody help me out?

[sig~] will convert floats to an MSP signal. If you want to smooth the result (in the audio domain) you could use rampsmooth~ or slide~

...and also maybe a [onepole~] at the source
