sure 8) The 4 identical circuits on the right side are oscillators that produce a triangle wave. The frequency/pitch of these oscillators can indeedbe adjusted with the 100K pots. (the way they are...

would it be okey to use Power Supply Adapter 9V DC with this circuit or should I change something? I'm asking because it uses a virtual ground, and have my doubts about when you can replace battery...

yes just leave the capacitor in but I would reduce it to 100nF..1uF since there is practically no load anymore which is the nice thingwhen using an opamp and the reaon it works. The problem with just...

if you add a pot after the capacitor you don't need the resistor anymore, but you could add an extra resistor in series to limit the maximum level.The 1nF will work as a low pass filter making it a bit...

Thank you for sharing the layoutsI like the combination of logic functions you chose for your Analog Logic design.Wanted to check that the inverters are separate from the logic not serial. So logic...

Although it might not be its intended use you could run it at a high frequency and use it as a custom wave shaper.Can be nice if you use a VCO as the CLK but keep in mind that the output frequency will...

So you do need to have a positive voltage on the accent in when you send a trigger. And as you see it's not tied to that -12V rail. When you're ready to come back to it, I would start at the trigger...
