The diode to the end out is to prevent triggering until the cycle is over. Without this you will be able to retrigger while the slope is falling. I’ve always wanted to try it out but for a basic bui ...

hi gang,
after finishing the sequencer thing (i need to post the schemo, sometime), i have layed down the soldering iron, and the friendly little voice in my head told me that it is time to quit.

Great!

This circuit has a special place in my heart -- it was the first thing I ever breadboarded, along with a simple trii-square oscillator, when I first got into this stuff.

This folder des ...

Great to see your progress -- I had been wondering what was happening! Good luck with the rest of the construction.

hope this helps

It really does. Thank you!

As luck would have it, I'm reading Horowitz and Hill The Art of Electronics at the moment, in my quest to understand and build some synthesizers, and ...

Thanks for the reply.

The 4066 discharging to ground, I think.

That was what I thought, but I still can't see how it works. When the triangle wave output (i.e. voltage at the lower plate of the ...

This is the VCO circuit that I am using.

Sorry to be a pain... I can't understand how that circuit works at all. Why doesn't the op-amp integrator just ramp up forever i.e. to saturation and stay ...

That is thoroughly marvellous. The sound file you posted reminds me of the opening titles of TV science shows circa 1981. This is meant as a compliment!

Outstanding work.

Clearly this is an old post but perhaps still worth responding...

I've been taking a look at these mods in the last few days as I learn about electronics and build some synths.

From what I unde ...
