Bramson" Subject: Unplugging MIDI cables J R III mentioned unplugging serial cables. Can you / should you plug and unplug MIDI cables into equipment which is switched on? My experience with other equipment is Apple keyboard/mouse yes Apple Local talk net yes PC RS 232 yes PC thin ethernet you can unplug a cable from a station as long as you don't break the net PC parallel centronics avoid Mac SCSI definitely avoid On a connected subject, my MIDI setup is Yamaha Clavinova -----> PC with MPU 401 clone -----> Roland Sound Canvas (the sound canvas audio out is fed to the Clavinova audio in) I find the MIDI thru default connection may not come up depending on what order I switch on the kit. I try to stick to Yamaha, then Roland, then PC which works Any comments Steven Bramson sdb@jet.uk sdb@jet.uk ------------------------------ Date: Thu, 15 Jul 1993 18:11:00 EDT From: John Rossi III Subject: Re: Unplugging MIDI cables I have yet to find a problem with plugging and unplugging MIDI cables. Since the things are connected using optoisolators I would think that any kind of damage would be very unlikely. Also, they realized that the MIDI spec was for musicians (electronic musicians especially) who are very used to plugging and unplugging things while synthesizers are on.

You can not afraid to do it, because MIDI is optocoupled. Until no message is actually transmitted, there shouldn't be no unexpected effect too, because the current loop is unactive at idle time (take care on the 'active sensing') Maciej ------------------------------ Date: Thu, 15 Jul 1993 18:32:34 -0600 From: Mike Bishop Subject: Re: Unplugging MIDI cables I wouldn't recommend unplugging Mac ADB cables. You run a serious risk of frying your motherboard. Honest. Modem and printer are OK. -------------------------------------------------------------------------- | Michael Bishop | "Any technology sufficiently advanced is | | mbishop@linfield.edu | indistinguishable from magic." | | Linfield College | | | McMinnville Oregon | - Aurthur C Clarke | -------------------------------------------------------------------------- On Thu, 15 Jul 1993, Steven D.
