nice random

[human fly]

thought i’d share this little script for randomizing
a list of parameters with different values ranges.
(the seeder is by Possemo, and the min/max property
was from something by dnaldoog)

function randVoice()
-- This variable stops index issues during panel bootup
if panel:getRestoreState() == true or panel:getProgramState() == true then return end
-- -----------------------------------------------------
	local t=os.time()	--[random seeder]--
	local c=os.clock()
	math.randomseed(t*c)
-- -----------------------------------------------------
	local param=nil 
	local min=nil
	local max=nil
	local rnd=nil

	for i=1,21 do 
	param=tbl_voiceParam	--[Voice Edit params]--
	--[any value range]--
	min = param:getProperty("modulatorMin")
	max = param:getProperty("modulatorMax")
	rnd=math.random(min,max)
	param:setModulatorValue(rnd,false,false,false)
	end
end

i also tried to shorten it, but for some reason, the following
does not seem to work (bad argument):

--	for i=1,21 do 
--	--[any value range]--
--	tbl_voiceParam:getProperty("modulatorMin")
--	tbl_voiceParam:getProperty("modulatorMax")
--	rnd=math.random(min,max)
--	tbl_voiceParam:setModulatorValue(rnd,false,false,false)
--	end
--end

There is a better randomseed:
math.randomseed(Time.getMillisecondCounterHiRes())
The other one does not work correctly when using 32-Bit Ctrlr.

You aren’t using i anywhare in your loop. This will set the same parameter 21 times?

[human fly]

ok, i’ll check out your new seeder if you say the other
one has problems – working great here with 64bit.

sorry, that’s the forum omitting square brackets without
the space, i thought that was fixed because it appeared
ok when i posted. should read:

	for i=1,21 do 
	param=tbl_voiceParam[ i ]	--[ Voice Edit params ]--
	--[ any value range ]--
	min = param:getProperty("modulatorMin")
	max = param:getProperty("modulatorMax")
	rnd=math.random(min,max)
	param:setModulatorValue(rnd,false,false,false)
	end

hope it reads better now.

[human fly]

so this should also be:

--	for i=1,21 do 
--	--[any value range]--
--	tbl_voiceParam[ i ]:getProperty("modulatorMin")
--	tbl_voiceParam[ i ]:getProperty("modulatorMax")
--	rnd=math.random(min,max)
--	tbl_voiceParam[ i ]:setModulatorValue(rnd,false,false,false)
--	end
--end

i tried (tbl_voiceParam[ i ]) ,regular brackets, as well, and figure
it ought to work (?) so i don’t know how to do that. it’s just to skip
a stage, thought it would do that.

[Possemo]

Ah ok. I have seen this too. In some cases you have to put it in a variable first.

[human fly]

confirming that your new seeder is working fine.
thanks! (hope it isn’t producing pseudo-random?
s’pose not, if it depends on system clock)

i like your comment ‘in some cases’ LOL
would you like to elaborate?
(‘coz i’ve found some other interesting ‘in some
cases’ with some other stuff. i’ll have to get
together a post for those – found workarounds though.
like: you do *exactly the same thing, in the same context*
and in one case it works, but not in the second… wdf…)

[Possemo]

The newer seed uses a high resolution time counter. I guess it will produce a small number with many decimal points. This seems to work better on 32-Bit app than a big number randomseed. On x64 it doesn’t seem to make a difference. I saw the hires counter on a demo panel from atom. You can learn a lot when you check all demo panels carefully.

“in some cases”: I would say you have to use “interim” variables in some cases when you are accessing modulators such as panel:getModulatorByName etc.

[human fly]

interim variable, makes sense.
(think i figured out why the other thing wasn’t working)

[human fly]

ah: discovered something interesting…(change of topic, really,
this should be over on RX7 topic) …
i am checking my data reference lists with ‘print jobs’,
because i have to match 1,100 lists to 1,128 lists, for the
purpose of assigning voice numbers to midi note numbers.

i’m printing stuff out in a format that i can copy and paste
from the console into a table directly.

so i’ve discovered that i cannot have """ because it just
leaves the apostrophes open, …of course. i need to do this
because i’m displaying numbers concatenated with text, and
then concatenate a comma in apostrophes, so it’s ready to
just paste where i want it.

although it is not ‘recommended to mix " and ', i found
that i can do it for this purpose and get the result wanted.

ie: " ' "

anyway: that’s it for the random topic. i’m over on the RX7
thing now. 😉
