I wrangled my externals into one library of sorts. You can grab rfpg from Deken for macOS for the moment.

Includes:

• audio-rate ambisonics externals
• time-domain granular sampling external
• tonal pitch space model for an incoming sequence of MIDI pitch data
• tape delay synth
• fibonacci rhythm generator
  
  More later!

Pushed intel as well for macOS. Here's the lib for those who want to try it out now.

Do you have screenshot or demo of your external - patches in action?

This video is kinda old but it gets the point across. I need to make better helper patches.

Added a little [cipher] external to the rfpg library to allow you to encode and decode plain text against a keyword. v0.2 should be available from Deken shortly. Enjoy!
