So I wanted to test circuitlab's simulation capabilities and I keyed in Ken Stone's ADSR circuit (http://www.cgs.synth.net/modules/cgs78_env.html). Here is the circuit in circuitlab:

However, I can not seem to get a 100pt time domain simulation to finish. It gets to about 2% (3hours remaining) and then just stops.

@akrylik,

Welcome to CL.

Hmmm.

Try reducing the size of your time steps.

Have a read of:

Replacing the rail-less opamps with those with power pins might help.

Your initial conditions may be upsetting CL if it's only getting a far as 2%.

For help and ideas, search for tags:

In particular, see:

If all else fails, see (d) in:
