I can only say YES, yesterday I've played around with a PIC16F84 for the
first time, I surfed around and found a neat schemo for a serialport
interface that consists of only a few resistors and diodes. Hell the guy
has done a small pcb 
of about 4.5cm x 4 cm. Now I'm thinking about some applications like a drum
trigger sequencer (a la 808.) Or hook up a TLC548 as 8-bit ADC and read the
values from a row of 16 pots and store them. I imagine one could have a
rotary switch to select one of multiple "virtual" rows and modify them in
realtime with the row of pots. Finally output them on some DACs. A nice
thing about the PIC is that you can easily download the onboard EEPROM
memory, since all you have to do is to dump the memory back into a
HEX-file, and store it on a computer.

I'll be doing some projects with these. I'm sure. As for copying it, there
won't be more than downloading a HEX-file to a PIC, and building a cable
for the programmer.

What CPU are you using for it?
