A Python commandline tool to convert wavetables exported from Vital/Vitalium to a format suitable for the Korg modwave. Written with no platform-specific code, so it should run fine in Windows, MacOS, and Linux.
Vital's wavetable editor exports wavetables as 16 integer-bit-per-sample, 2048 sample-per-wave, 256 wave-per-wavetable .wav files. The modwave doesn't support these directly and they cannot be imported by the modwave librarian. modwavify converts this to a float32-per-sample, 2048 sample-per-wave, 64 wave-per-wavetable .wav file, which can be imported by the modwave. It also always normalizes the wave amplitude.
> python modwavify.py wavetable.wavwavetable.wav: 88200 samples, Max excursion 0.371002197265625wavetable_mw.wav: reduced by factor 4 to 64 waves
This produces two files:wavetable_mw.wav and wavetable.png
wavetable.png is a waterfall plot, generated by default, that displays the wavetable.
Example wavetable plot:

The simplest way is to install the dependencies using pip
> pip install -r requirements.txt
