What are you using for probes? I have a real scope but it doesnt record and it's very difficult to lock on complex waveforms, so this might actually be useful...

Yes, I'm really enjoying using it! I've had access to nice scopes from my girls dads work at home in NZ, but they are finicky things to use, this just works :-)

Because it's only 5V and audio signals can be that high, i just have it interfaced directly. The input impedance of my card is about 100k Ohms, and it is capacitively coupled.

The software hasn't changed in about 2 years or so. I did see a few bugs, but nothing worth fixing.
