MIDI micro controller

I am looking for suggestions on good microcontrollers that can
withstand tuff temperatures and are able to do midi properly. I have
tried the atmega48 and it is not stable. Any solutions / ideas?

I can't answer your question but I'm curious: are you talking about MIDI as 
in music? If so, what kind of musical application needs to withstand tuff 
temperatures?

What do you think is hard temperatures ?

I am just returning from a very nice social event tonight, in which we
spent quite a while in a sauna with temperatures of 90 .. 120 C and
then went swimming into a hole in a frozen lake (0 C) despite the
minor blizzard today. I didn't carry any electronics with me, since I
did not expect that it would survive that treatment.

If you really need products that works with a large temperature range,
I would at least check that the product supports the military -55 ..
+125 C temperature range.

   The Industrial Temperature part are more affordable.
without the OPs input it is just a guess.

All of it that's ever used live on-stage.  Temperatures on a crowded,
lighted stage can be quite a challenge.  You stand in the focus of a
couple dozen kilowatts of lights for a while, you'll immediately know
what I mean.  Not to mention issues like tube amplifiers for guitars
being plugged in carelessly, electrocuting the first person to touch
the wrong piece of equipment, fritzing all unprotected electronics
encountered while at it.

Equipment that's supposed to survive your average band's tour for more
than a month has to be *tough*.  From an engineering point of view,
the whole activity is just a massive practical realization of Murphy's
law.

Even if all the snow were burnt, ashes would remain.

Use an external crystal instead of relying on the internal R/C oscillator
