testers for random chord sequencer

how would i make the names readable? i’m on windows which doesn’t have address sanitizer but i could try to run rack in a linux vm for that.

I think there is a way to use standard tools that you already have to “un mangle” the names. There might even be a web site that will do it - but I don’t know myself

Yeah, ASAN. In my experience it’s easy to use on mac, possible to use in Linux, and I have never tried on windows. It’s enough of a pain to try on linux that I can’t with good concience recommend that, esp if you don’t already have a Linux VM set up. I have done it twice when I had mysterious crashes, but… It would probably be much easier to get all the free plugins required to load @rsmus7 's patch and try to report.

Totally unrelated, if you stay in this “business” you will want a linux VM, for a variety of reasons.

I just had the Audio-8 module loaded and just when I want to load the RandomChordRecorder VCV crashes.

So, from my last log file:

I use the FL Studio ASIO driver on my WIN10 Ryzen laptop

There’s a known issue with random number generator seeding in windows using time. I ran into it and it was a pita to figure out.

Look at some of my (frozen wasteland) modules that use probability (and there are a few) and see how I do the seeding

thanks, i see you use srand(time(NULL)); in the constructor, i’m not sure if that will work with what i was doing though, because i’m using random_device

Yeah, don’t use random device

I was using random device because the discrete_distribution function uses that, do you know if that would be usable with srand? I could just write up my own function to get a weighted random distribution but i don’t want to reinvent the wheel if i don’t have to.

I think you may be over complicating things - you can still use std::random, you just need to change how you seed it (as mentioned above). Most other random distributions are derived from that base random function, so you should not need to do anything very esoteric unless you really want to

Hoping this helps.

I’ve run into this issue with building (I build nearly everything myself) some plugins on Windows. One of the latest is a Pull Request I’ve made for SilverMoss (yet to be released.)

This PR shows how I’ve fixed this issue. It’s to do with what version of GCC one uses to compile the code. The background, if you’re interested, is linked there as well.

Like Eric said avoid random device. You can however seed using time; in this case use time(0) as well as the necessary #include <ctime>

I’ll submit a PR to your repo for review.

thanks! i had released it already on vcv library but i intended to fix it. i just want to double check by building it on my computer and then i’ll approve the pull request and change the version so it’s not broken in vcv library.

No problem, glad to help.
