I wanted to ask what experiences people have had overseas with the voltage conversion issue? Has Max/msp and MIDI acted unpredictable? I would like to compare notes.

in between japan, US and europe, with different versions of macmsp 

jitter, on various mac powerbooks, i've never experienced anything 

most of the time the sound card was an RME, also with a power supply

I tried that as well... and all my audio came out an octave too high.

If you're on Mac (why, why, why don't people ever say what hardware 

they're using???), the built in power supplies have accepted 100-240V 

50-60 Hz ever since the SE came out in 1985/86.

The only thing you need is an appropriate adapter for the plug. You 

can pick one up at an airport drugstore for a few bucks/quid/euros.

After showering MSP with 'Axe for Men' the audio returned to its 

usual octave range, but only if I used the abdul~ object.

Which reminds me: does anyone have a spare fuse~ ?

Not true - there's at least a generation of US-market G4 towers which 

accept 110V only (and, I think, at least one generation of "white 

monolith" G5 iMacs which is the same). European Mac hardware is 

universal voltage; US Mac hardware is perhaps not.

OK, I've not checked every model that's come out of every factory. 

Apple first started using universal power supplies in SEs (US built, 

also). It is a cost point and Apple's US-based factories may have 

been more inclined to scrimp on this than Cork has (what red-blooded 

American would take a computer outside the country anyway?-)

So the most reliable thing is to buy your Mac in Europe in the first

With a Powerbook and a bus powered interface there should be no problem. 

I just soldered some additional connectors to a small universal 

switching power supply to get rid of my collection of transformers which 

used to power my faderboxes (all 9 V). Works like a charm, runs from 

100v - 240 V and is so much smaller and lighter...

This is another advantage of a computer only setup, easier to run it

Here it is, it's a modern one, you don't need to replace it if its 

blown, just send a 1 to the left inlet. But it's set to 240 as default, 

in the us you should give it an argument of 110, though 120 doesn't seem
