Tuner preset question

Does anyone know of a way to set presets on the tuner outside of the car? Perhaps there's an file that can be edited so I could go in and specify the desired frequencies and such while I have it connected to my PC?

Er. No. The radio presets are stored in the same place as the EQ and persistant playlist. There's currently no way to edit these with the supplied software.

I wasn't necessarily refering to supplied software. I was just asking if that information exists on the player in a format that makes it possible to edit, perhaps with other tools.

Hmmm..would have been a better post for the technical forum, I guess.

Right.

No, it's not a file.

No, the format is not public. (Unofficially) you can reverse engineer it if you feel like it. The format will change in v2.0

We don't provide any software to edit it. I don't know of anyone else who does, either.


Roger - not necessarily speaking for empeg

To elaborate on what Roger just said...

The information is stored on what's called the "scratch" partition on the player. It's not in a standard file format and can't be accessed in the normal way. It's proprietary to the Empeg.

There are those who have been begging for a way to edit/backup/restore the equalizer presets, which are stored the same way, but no one has yet tried to reverse-engineer a way to read/write from that scratch partition.

Roger... can you drop a hint? Is there anything in the Emptool sources that will allow a program running on the PC to send and receive data from this partition? Or must you be a piece of software running on the Empeg in order to access it?

Is there anything in the Emptool sources

No. There's currently nothing in the protocol to allow reading the scratch partition. This has two implications:

1. The format is undocumented.
2. You'd have to play with it on the empeg, rather than the PC.

Couldn't you just use 'dd' to copy the entire partition to a file? What other stuff is in that partition? I'd imagine that the current song, or similar is also stored here.

Yes you could, but the original question was how to edit the presets away from the empeg.

Yes. The next step towards reverse engineering it would be to copy it with dd to a file, change a single preset in a minimal way, then copy the partition to another file and compare the two files. Doing one change at a time in this way would probably tell you where most of the information goes.

I don't have a tuner yet so I'll have to pass on this for now.
