2x 10kΩ resistor
1x 100kΩ resistor
1x 1kΩ resistor

2x 10kΩ potentiometer (4.7 kΩ or 100 kΩ might be Ok too, for the range and bias controls)
This is an updated version of the first shot of this project. Thanks to all the people from the Look Mum No Computer forum who helped me to correct the mistakes made in its early version.
Also, a big thank you to first_blursed on Discord who helped me to “beta-test” this version.

You can find the thread on the LMNC forum here : https://lookmumnocomputer.discourse.group/t/arduino-arpegiator-module/2581 (Thanks to Sound Bender for posting this project in the forum).

I didn’t put it here, but maybe using an Op-Amp buffer at the Pitch Output could protect the analog out of the MCP4725.
