As I've probably said before, I like the "ugliness" of the way that is
done personally. For me, the orchestra is only the "how" component of
music, and giving it such an opcode seems contrary to Music-N
principle. As for the limit to the number of arguments you can give
linseg, I think it's the same for every other opcode.

Nice, thanks. Do you know what the limit for number of inputs is for UDOs?

Hi Richard

Thanks for your answer, but that's not what I'm looking for. I think I wasn't clear enough earlier.

I often control parameters in my pieces in a separate instrument that is on from beginning to end and only consists of linsegs and expsegs with lots of parameters. Usually, I want to specify what certain values ought to be at absolute times in my piece, and then interpolate between those values. Here's an example:

0 at beginning of performance

1 at 5s   into the performance,

2 at 30s into the performance,

0 at 1:30min into the performance

Using linseg, I always have to calculate the differences between the absolute times and use those:

kvalue linseg 0, 5, 1, 25, 2, 60, 0

Not only is this tedious (especially if there a many control points), but it is also prone to errors, as changing one duration changes everything that follows after it.

Alex

P.S. Is there a limit on how many parameters can be specified with linseg? I remember a while back I got some erratic behavior with a linseg that had a couple hundred (IIRC) parameters.

By the way: Is there a limit on how many parameters linseg can take?

Actually this may be an idea for future development.

An alternative to GEN27 that takes in x values in seconds and internally normalizes them to fit within the table. I don't suppose that this will be too difficult to implement right?

So this:

f 1 0 8193 (-27) 0 1 10 0

would be internally converted to:

f 1 0 8193 (-27) 0 1 8192 0

Then using an oscil with 1/p3 as frequency value should reproduce the bpf.

Best,

Peiman

Correction:

Then using an oscil with 1/10 as frequency value should reproduce the bpf.

I'm adding a linseg etc based on breakpoints, which is very easy to do. Will report when done.
