Just getting a single pitch (base-freq) is not too hard. You can use the 'fiddle~' or 'sigmund~' ugens of Pure-data. [There's also code floating around in various languages that do similar (eg. zita-at1 in C), or various filters that you could hook together.., but Pd is probably the easiest to start with. Once you have the frequency, just convert it into a MIDI message or feed it into a synth.] It's easy enough: just open the 'fiddle~' help in pure-data and connect an 'adc~' to the 'fiddle~' input. The first output (printed to console in the help-example) shows the detected midi-pitch. Well, if you're new to this; maybe start at http://en.flossmanuals.net/puredata/ If you're lost I could whip up a simple example Pd-patch. or just ask follow-up questions on the list... have fun, robin
