How would you make an optimized 4 sample interpolation between 2 consecutive values ?

ps : Long time I have not posted something ! :)

If I understand well, there is no already prepared "line" external. :)

Here is a piece of code that interpolates from one sample to the next within a minimum amount of time. The interpolation starts as soon as a new signal value arrives. Also, it works like a line for new incoming values when interpolation has not ended yet.

I have noticed History does not work when it is outside of a function.

Ohh thanks!

It's probably less sophisticated that what you're looking for, but here's a pseudo-line~ for gen~:

Whoops, loadmess was firing to soon. Try this:

i thought it would be very simple to turn this into a reusable function. but it isn't. why will this not compile? the errors are cryptic. (and i think 'step' was superfluous?).

You're right, step was superfluous -- a bit of code that wasn't being used anymore.

Why it doesn't compile is being looked into, flagged as ticket #3633.
