Hi,
before I start programming wanted to ask: does anyone knows / has made any
patches to populate an array with values? something like "make 10 values
between X and Y", being at a constant rate, or following an exponential
curve, or with (more or less) random deviations, ...
Thanks,
João

Here's an example that fills an array with a tanh curve, you need to enable audio for [phasor~] to do its job, then hit the bang to fill the table.

[#for 0 10 1] | [# something...] <- put function here | [#to_list] | [list prepend 0] | [s $0-myarrayname]
or
[#for 0 10 1] | [#to_list] | [list-map]x[something...] <- put function here | [list prepend 0] | [s $0-myarrayname]
and so on.
if you want random distributions, then those are defined in many more parameters than just an average value and an average deviation from that value. there are as many kinds of randomness as there are kinds of everything else. You can generate independent randomness (each sample is separate from each other) or you can make them related (random walks, markov chains, and more). First, you need to know what kind of effect you'd like to achieve or what you'd like to imitate, and after that, I can help you some more...
simple random walk in gridflow :
[#for 0 10 1] | [# put 2] | [# rand] | [# * 2] | [# - 1] | [#scan +] | [#to_list] | ...
first two boxes do the same as a «10 # 2» message in this case, because we just need to send the value «2» ten times to the randomizer, to flip a coin ten times...

do these objects have a counterpart in Pd? I wanted to avoid using still
another version of the program.

I'll try out several distributions and envelopes (increasing/decreasing
envelope, etc.). There are already several random distribution objects
around, which I'm thinking of using.

what other version of pd would you need ??
If you use pd-extended, then it's just a matter of downloading an extra package of externals from http://gridflow.ca/ ... it could take 2 minutes.
