Feature Request - Minimal change option

[dege13]

I love using your AutoTracker as background music as I work. Sometimes I noticed that the next pattern is very different and it can be startling. I would love a feature to enable an option to change less per new pattern.

For example;
You start with no seed provided and it generate a seed of [0x020102A4CD0887CB0B]
When that has played, if the option is checked, only one digit changes therefore making it sound like the same song but only changing one thing. The seed is now [0x050102A4CD0887CB0B]
Once this one has played, the next change is again minimal, like [0x050102A46D0887AB0B]

To make it more usable to more people, you could even make it a slider to choose how much 'randomness' to include in the next pattern.

I would try to make this change myself in a Fork but I am not much of a software developer.
If you do not want to do it, I totally understand. I love your program either way.
