Adding new waveforms to the list

[GIBA-BDV]

Hi,

I'm Giovanni from Brazil, then sorry for my poor English. I'm not a developer too.
I'm new on asking thinks on GitHub. Correct me if I'm wrong, please.

Does have any simple way to add two new waveform in the Organ?
I would like to add a triangular and a 9 step piramid waveform to the organ.

The ideia is to imitate a Vox and a Farfisa organ. I tested it on Helm Synth and it sound like good to me.

Thanks to the support.
