Sure is Lo-Fi. I assume you're the same Lo-fi_Masshkah from the electro-music forums? :) I should be getting all the parts I need for a MIDIBox SID over the next couple of weeks. Can't wait to put it all together. I just finished the Soundlab DIY analogue synth, and the sound is great. It's amazing how you can get such good quality equipment from DIY'ing. Just a quick question though, can I ask where you got your SID chip from? Did you just get an old C64 or something? I've seen the link to the place that sells 6581's for 25 euro's, but that seems a bit steep... you can get a second hand C64 for that much!
