Thanks for the reply marcos! This doesn't vary the random seed though, so the condition would always be one of 10 values.

hagagogu's original question about the random seed hasn't been addressed. The random seed is different from a random number.
Since hagagogu has not clarified their reason for wanting to set the random seed, it has been difficult to respond.
Typically each time you run pianoteq, and click the dice, you get a random set of parameters. I assume that this series will be different each time you run pianoteq (although I haven't tried it recently). This is typically what we expect from random. So if you start pianoteq, and click the dice once, then you get a setup that you haven't seen before, and when you run pianoteq again later, and click the dice once, you will get a different random setup.

Setting the random seed is typically for purposes that require repeatability. For example, you click the dice three times, and you get three unique random setups.
Then the next time you run pianoteq you wish to get exactly the same three setups for the first three clicks.
You would accomplish this by setting the random seed to a known value, each time you start pianoteq. Typically if you do not set the random seed explicitly, then the system clock will be used to initialize the seed to a value based on the clock and which will therefore be different each time you run.
I am not sure if hagagogu is trying to get repeatability. If not, then I am not sure what they are after, or perhaps they are using the term 'random seed' incorrectly. It would be good if they can clarify their use case.

In any case I am not aware of a way to explicitly set the random seed in pianoteq, but such a feature likely exists because software testers will often find this useful. They may want to achieve repeatability when running tests that involve random numbers.

Since English is not my native language, maybe I didn't understand correctly what a random seed is. In any case, the possible values the script gives are 0, 0.01, 0.02, ..., 9.98, 9.99, 10, which are taken pseudo-randomly.

I asked Bing AI... in Windows this could be done by the following commands in the PowerShell:

The description is as follows:
cd 'C:\Program Files\Modartt\Pianoteq 8\': change the actual directory to Pianoteq's
$random_number = Get-Random: gets a random number between 0 and 2147483647, which is 2^31-1
echo $random_number: just prints the number to the screen, it is not necessary
$divisor = 214748364.7: 2147483647/10; in order to get a number between 0 and 10
$condition = $random_number/$divisor: this calculation will 'normalize' the random number between 0 and 10
echo $condition: just check the result
& '.\Pianoteq 8.exe' --set-param Condition=$condition: runs Pianoteq with the condition

All this can be run without typing each time by saving it on a text file with the extension .ps1 (the extension of the Windows' PowerShell).

I have also asked the AI for Linux, but I can't post it here since I don't know if the answer works (I must confess with shame that I have stopped using Linux lately, and at this moment I do not have the devices on which I run it on hand). But if this is what you need, you can try and post the results here...

Thanks for the reply marcos! This doesn't vary the random seed though, so the condition would always be one of 10 values.

I assume you are running Pianoteq from the command line. If so, run "pianoteq --help" and see if there is an option there for what you are trying to do. If not, there is likely no solution, but you could contact Modartt directly to verify.

Of course you can remove the "print" stuff.

For some reason, the same script does not work under Windows 10, this slighty modified version does work (again, I believe the culprit are the /, spaces and "" usage... in fact I first wrote it under windows and then noticed it did not work under Linux, so this is the original version):

I hope it helps,

A separate question, is it possible to use the randomize (dice) button on the command line?

Thank you!
