The Arduino forum really sucks. There are consultants who, instead of clear help, give you riddles - for a person who is confused enough, this is not much of a help. If you try to explain something and ask some stupid (in their opinion) questions, you will be slapped in the face and eaten by the community when you try to argue. A fantastic experience. I recommend to everyone.
As for open source. I don't know. I would rather share this software with a person or a team who would involve to further development. But I would need a proof of involvement in Fruit Machines community growth, and some programming skills. I do not want to give away this software to anyone without any control of the source code. It was a lot of work for me. I had to learn a lot of things to make it working. You know, this small piece of software has a big value for me. I don't wat it to be spoiled.
And maybe some day I will get back to it by myself? Who knows...
