It has code that could potentially generate negative values, for example:\n```go\nMutate is:\ni.baseValues.attack += frnd(0.1) - 0.05\n\nRandom is:\no.baseValues.attack = cube(rndr(-1.0, 1.0))\n```\nOne kind of fix would be to *abs(add 0.5)* to anything \u003c 0.\n\nThe fix for Random would be to check what the range is and use that instead of hardcoded (-1,1)\n\n# Menus\n- Generators\n- Wave Forms\n- Volume slider\n- Save\n    - sfxr\n    - wave\n- Load\n    - sfxr\n- Sample Rate\n    - 44 KHz (default)\n    - 22 KHz\n    - 11 KHz\n    - 5.5 KHz\n- Sample Size\n    - 16 bits\n    - 8 bits (default)\n- About\n\n# Tasks\n- ☑ Settings sliders\n- ☑ State management.
