Who knows what he wants.

My MAudio Transit USB soundcard actually does really well.

But if it is internally digital why in the world are you changing it back to analog and then back to digital within the soundcard. You want it to output digital. In which case he does not want a line input either. He wants a digital input ( possibly just a usb line). Weirder and weirder. > > > [1] At least, I think it does contain all those effects.

Possibly. ;) I am still wondering if he ever bought that ATI video graphics card or an Nvidia video graphics card instead. <http://www.keyongtech.COM/5521089-radeon-hd-5570-on-linux> I fear that we will never know ...

That's pretty much it, with the sole exception that the POD x3 isn't exactly small nor battery-powered. It's a desktop effects processor and the successor of the PODxt and POD 2.0. The one which is battery powered is the pocket POD. Rui Maciel |
