I am using the curve~ object in order to be able to read a sample also with a non-linear increment. It seems to work as I expected except when I set the coefficient to zero because I still feel a minimal pitch variation. Then, I am going to ask you: is it possible that the curve~ object, also with a coefficient zero, is not able to produce the same result as the line~ object - in other words, a properly linear increment? Or is it just a wrong feeling by my side?

Waiting for replies, I thanks in advance.

Hello all,

I don't think it's possible. I had a patch which scanned through samples using either function and curve~ or function and line~. Even if the curve was set to 0 there would still be some pitch variation. I'd love to hear otherwise though....

Makes me long once more for a new function - with the best bits of sa.function and function but in the standard Max package.

Anyway, it's really a pitty that the curve~ object - despite it seems, in my opinion, to be a kind of improvement of the line~ object - actually isn't able to output its same result.

And so, if possible, I'd like to ask you for other clarifications about this issue: well, if I am not wrong, what is possible to be generated with curve~ is nothing than a Bezier quadratic curve; in theory, when the coefficient is equal to zero, it means that P1 is placed on the segment from P0 to P2. So the question is: is it possible to obtain a higher precision result materializing the Bezier quadratic curve equation in Max? If not, why? What are the main elements that don't allow this?

Thanks for your clear demonstration.

Is it possible... I expect so. I'd hazard a guess that you can do that with expr in gen~, distorting line~. It's a bit out of my comfort zone though, so perhaps someone else can chip in here.

Then, I will try to make a simple patch during the Easter holiday. If it seems to work correctly, with pleasure, I will share and upload it to this forum.
