I finally got round to making a video showing the filter in use. I programmed the front end to play the intro to “Fox on the Run” by Sweet forever – that’s my personal idea of synth heaven, by the way – and also allow me to twiddle knobs at the same time to save you suffering from my ham-fisted ‘playing’ – enjoy!
The live sound here is half DI into my Mac, half the sound picked up by the camera, partly so you can hear fingers pulling on controllers, and partly so that it’s obvious it’s a real live recording. Unfortunately the camera has introduced a pile of hiss and background noise as well, but you can’t win ’em all.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
