hey Pete
A new soundcard (or line6 toneport) will just reroute the signal away from GT3 and only avoid the issue. It does not fix the issue. It has been noted as a suggestion so please do not rant and rave about this.
huh, this is bollox. the soundcard/driver merely takes an analogue signal, converts it to 0s and 1s, feeds that audio stream to the software host (GT3 in your case), and takes the audio stream out of GT3 and converts it back to electrical pulses. Whatever soundcard you use, this is what it does. now, some cards can offer you mixing options which takes the A/D part out of the round-trip equation and merely splits the input straight to the output to meet the D/A stream from the software - and halve the latency. or some of us use mixers to get hardware near-zero monitoring. whatever. the point is - efficient semi-pro or pro cards and drivers are the answer.
yes i know the whole sorry sordid history of your threads.
now, this means that clearly the efficiency of your soundcard driver is crucial, ie the time it takes to convert your Analouge data to Digital and vice-versa. So, your onboard soundcard can do this, but slowly, whereas your dedicated pro soundcard does it that much more quickly (to say nothing of quality)
