My interpretation of the Moog Bode 1630 Frequency Shifter. This uses a Teensy 4.0 with the Teensy Audio shield. Note that this is a frequency shifter, not a pitch shifter.
The open source software is programmed using the Arduino IDE and is based on the Teensy 32-bit floating point audio library:

On the video there is a slight audio glitch when moving from up to down shift (and vice-versa), this has now been fixed.
The sound file excerpts used are from the Teensy Audio library website:
