re: MAX/msp and international voltage

    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. Jeff

      in between japan, US and europe, with different versions of macmsp jitter, on various mac powerbooks, i've never experienced anything voltage-related. most of the time the sound card was an RME, also with a power supply accepting 110-240

      recently we tried the 110 Volt version of jitter with the 220 Volt version of MAXMSP, and what i should i say, only half the picture was displayed!

      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 place.-

      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 from switching powersupplies...

      Yes, but this happens only if you mix them, usually only possible half way between europe and us. I'd note, that the other way round will lower the volume... If Jitter and Max run with the same voltage it will level out, but if you mix the 50 Hz/60Hz as well, you should have noticed that the crashing frequency goes down, the crashreporter is probably confused and doesn't know wich cycle to count and seems to miss the points of crash... Recent research assumes its because the beating frequency will have only a Max at 10 Hz, which fits to our observation of the relationship between power cycles and cycling74 crashes. Probably a some sort of cycle jealousy. If you rename the cycling74 folder the crashes go away, but then Max has other problems...

      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 to hurt...
