Loopi is growing some nice features.
Loopi is a radial sonogram paint program.
It's a whole lot like RGS, even sharing its color scheme for the sonogram.
You can make up to 30 second samples by drawing their sonograms.
Many of RGS' "pens" are available.
Right now, I'm trying to get the recording/heterodyne filter part to work on the device, which works in the simulator. With that, you can record
audio and turn it into a Loopi radial sonogram and alter it.
Loopi will also be able to save its songrams, parameters and sounds and allow sharing of these entities.
