Hi,
Nice work with the sequencer, i'm going to make a 16 step version of it.
I'm a newbie in electronics so I have got a question : what's that thing that comes out of pin 3 of the TL071 and go in a 10k resistor "sensivity" ? what does the "sensivity" means ? also, what about the transistors just before the output jack ? How are they linked ?
Thank you for answering, it'll be helpful !
