Ornament and Crime Optimized With Teensy 4.1

Check out SynthDad's What's New and Improved video for demo of O_C T4.1 capability.

While porting the Ornament and Crime code to run on Teensy 4, the question kept coming up "what can a 600 MHz processor let me do". Turns out the extra memory allows Phazerville firmware to support all applets in a single image. But the original hardware designed for Teensy 3.2 limits what Teensy 4.0 can do. The necessity to share a single SPI…
