The processor in the Pronto isn't fast enough to capture very high carrier frequencies (455 KHz and 1.125 MHz). When you're trying to keep the price under control and make the batteries last, something has to give :-)

We'd actually like to get our hands on some of the older Pioneer remotes with the 1.125 MHz carrier. If you are willing to donate a Pioneer remote (an older one that Pronto can't learn obviously - all the current Pioneer models work fine), please let me know by email.

We'll do our best to capture the codes, and make them available to ProntEdit users. Though Pronto can't capture those codes, it should be able to reproduce them without problems.
