What can Tonto do that ProntoEdit can't do? I'm trying to decide if it is worth the learning curve to learn to use Tonto.

Tonto is based on PE, so I don't think there will be much of a learning curve. Some of the big differences are

1) written in Java, so works on any platform
2) better comport use
3) you can open multiple CCFs at the same time (and copy from one to the other)

Overall, in my opinion, Tonto is more intuitive and user friendly.
The learning curve will be minimal.

Tonto supports Theme Mastering and Tab Mastering (wish I'd checked this before doing my own CCF!) which are handy features. It is also more rigorous in learning codes - requiring a number of repetitions (which you can set) to ensure that you really get a clean code. The downside is that it does appear slower with screen redraws (probably a Java issue) and the learning process involves rather a lot of button clicking.

Tonto works smoother.
I have less problems when downloading into the remote (RU940) when using Tonto.
I love the copy paste feature (merging sucks, as you have to remember which file to open first etc...)

Learning curve is very steep (if you have used PE before) Both programs work in a similar way.

If using Tonto, remember to insert the path for the emulator (it uses the PE emulator)

Tonto can open files of Marantz, Pronto and Yamaha types.

I have found that if I make a Pronto ccf and open it with the Marantz program, it will work (I don't use timers).

If I open a Marantz ccf with ProntoEdit, the codes are gone.

Could it be that when you open a file with Tonto, you can convert it to another type without losing the codes? You would of course lose timers going to Marantz, and the larger Marantz screen size would affect storing a Marantz ccf as a Pronto...

anybody know about this?

What I like most about Tonto is the ease of button management. Actions can be copied and pasted between buttons/panels without opening windows (by drag 'n drop or right-click), icons can be easily swapped, panel buttons can be wired as aliases to IR panels by just copy and paste (rather than choosing them through scrolling dialog lists).

The amount of effort required to build a complex ccf (or customize someone else's ccf to your own setup) takes far less time.

Tonto also does a fair job at adapting one ccf to another (screen sizes, and Pronto <--> Marantz conversions).

Give yourself an evening fooling around with Tonto and you'll never go back.

I disagree with buxe (though perhaps I misunderstand), since I found the learning curve for Tonto to be fairly straightforward if one has used ProntoEdit or Touch Screen Setup in the past. Note: I would definitely not recommend learning how to do ccf programming with Tonto since it assumes one has ProntoEdit skills. Learn PE or TSS first then graduate to Tonto when you have the basics down (i.e., use Tonto for your second ccf project).

How and where does one insert the path for the emulator?

Under "File", then "Preferences", and "Helpers".
