I think I found a bug. What should I do?
Send me an email at [email protected] and I'll fix it! Include information like what happened, a crash report if you have one, the operating system you're using (GNU/Linux, Mac OSX, Windows), if you're using the plugin version or standalone and any other info you think is useful.
I'd like to help out! What can I do?
Besides paying for Helm, testing and reporting bugs is very helpful. I'd also really love sound samples, songs and any patches you've created that I can distribute with Helm.
