audiocommander, Hope you had a great holiday. I got my pic 16f already programmed with V1.2 from smashtv. I hope that's the latest version. I only have one a couple of questions, which pic do you recommend for the core the 18f4620 or the 18f4685? Does the firmware only access the speech or does it also give access to the synth parts of the SJ when using the hand tracker kII? If so, can it be user selected? I purchased some IR sensors form acroname. Do they interface directly to the analog inputs of the core? if so, can you tell me which pins to which sensor (assuming the diagram you posted before). Thanks, James
