Reducing capacitor click without lowering output current

[ExpAnonColin]

So let's say you've built a metronome based on an RC circuit...  How would you destroy the click's without lowering the total output current, and while maintaining the same frequency?  Id've thought that a high value resistor to ground from the outboard side of the cap would do it, but apparently not.  Anyone?

Can you explain more? Do you mean that you want a more bassy, less trebly click out of the metronome? Or something else?

No, I want no clickat all-I swear I knew how to do it, basically I just want the circuit to attack the click so it's not there.

I did it with the EHX small clone, to make the tremolo not click at the top of each square wave, but this just isn't working.

A metronome with no clicking?  :?

? ?

That's like airline food.

Well, I'm not using a metronome (just a good example), I'm just using cancelling out capacitor outburst voltages while still using them for timing.

Ahhhhh.... OK, that makes more sense....

You need a low-pass filter, A.K.A. and integrator.

Try putting a resistor on the 555 output and then a cap from the other side of the resistor to ground. Take your signal from the junction between the resistor and cap. The real trick is to find the combination of values that still gives you the proper level to do the switching you want over the whole frequency range you want to be able to use.

As the 555 changes state, the cap will resist the fast transition and the resistor will limit the charging current directly from the chip. The end result is a slower rise and fall of the square wave.

Another option to think about is to use a triangle wave osc. instead of the square. That will be more consistant over a large frequency range, but the circuit you're clocking might not like it (esp. if it's CMOS).

Any clues about what the clock goes into?

I'm not using a 555.  It's just an RC circuit.... and I swear to god I did it with resistance in the small clone, no lopasses involved... I really don't want to have to pull an extra lowpass for this.

I'll try the resistor-dual cap idea, thanks for that, I tried a cap to ground and a resistor to ground but not another combo.

Nope, still isn't working.  Oh well, no big deal, I'll suffice.
