hi Jeffrey, I ll try and post some pics next week. My setup is nothing special: - a Dell laptop (core 2 duo, 1,6 Ghz, and 0,9 GB of RAM) - an EMU 0404 usb soundcard - Fedora 12 with a rt kernel, JACK and Pd-extended - an electric guitar, and some custom foot controllers based on a cheap usb gamepad.
I get about 5ms of latency, maybe 4.5. I don't do anything too fancy in Pd, because it needs to be playable (i play in a rock band), but i can process both my guitar and my voice in real time without dropouts (and i use some rather cpu-intensive patches, based on fft analysis and stuff). The only tricky thing i was faced with when trying to put this setup together was the output impedence of my soundcard, which had to match that of my amp's input (i bought a shure impedence matching transformer and it solved the problem). Hope it helps.
