I wrote a program to generate sweeping up and down tones, with user controls.
What I wasn't able to do was get this code into executable form for simple installation.
So, you'll need to install Miniconda (Python 3.8, 64-bit), then go into the uncompressed directory and type
conda env create --file scalar.yml
Then, to run the program:
conda activate scalar
The GUI should be self-explanatory.
If you have any questions or issues, post them below.
