Here are some of my better first attempts at using sandify. I think I shared them with the link befow. You are welcome to mirror them on your public dropbox aswell and I hope everyone enjoys them.
I'm not super good at forums and file sharing so let me know if the link doesn't work.
Welcome to our forum, Doug! And thanks for sharing these. We are phasing out of using a Dropbox folder for public tracks, now that we have opened our Community section of the app (at long last!). All you need to do is log in at webcenter.sisyphus-industries.com, and then upload your tracks. Thumbnail images of the tracks will auto-generate, and so people can get an idea of the what the track will look like before downloading and running them.
Also - a nice feature of Sandify is that it allows you to view track files - just click on the Code tab, and then the "Click to load" under the Theta Rho Input heading. The track will be drawn in the black field, and there is a slider at the bottom which steps you through the path's course.
