Rewire (or sync) between two laptops

jnchrls · Post by **jnchrls** » Sat Oct 19, 2002 7:32 pm

Can this be done? I want to play with my bandmates using two powerbooks. Would it be possible to run reason on one laptop and rewire it to live on another laptop? If so, could it be done using airport cards? Any suggestions would be great.

Run a MIDI cable from the OUT of the Live machine to the IN of the Reason machine. Set Live to transmit master clock, and set Reason to sync to clock. This process is detailed in the product manuals.

.. and going further you most probably could run your Audio Out of your Reasonbox , into your Audio In of your Live box .... using Live as your virtual mixer for both machines ... all sync'd together ...

i've no idea how yet...but the minute max/msp is ready for osx, i'm gonna attempt to whip something up that allows rewiring between two laptops via the ethernet port. i see no reason why it shouldn't work (pun intended). this way i can use one machine for pure synthesis and sampling and just run the output over to the other machine which will handle all my i/o, eliminating the need for a second soundcard and all that 'tweaking my latency settings' to get it actually synced, and freeing up some usb/firewire ports by using the never-really-used-for-audio ethernet port. there's prolly a bunch of holes in this theory, but i've heard umpteen million times that if you can think it up, max/msp can do it. i'll let y'all know if and when i get it going.

Rewire over IP is something I'd really like to see...

i don't think it'd work very well over a regular 100Mbit connection. too much data to fast.. you'd bottleneck faster than fast. now Gbit over copper (which all new macs have

) might do the trick.

All,

I have used an app called MidiViaNet that works to send midi sync over a net connection. You'd have to use virtual midi like midiyoke but it works great, Only problem is they only made it only for win98, not 2k, xp or OSX. Do a search for it, maybe someone could hack a new version.

Wireless midi can work.

crumby, no-gigabit-havin' powerbook 400.

i think a 100mbit ethernet connection should work for at least a stereo rewire transfer. isn't 100mbit ethernet capable of 12.5 megs a second? albeit that's best case scenario, but that should be more than enough for at least a few channels. unless i'm just fuckin' retarded...

I've been looking all over the net for an open source midi over lan code. So far the only apps I've found are MIDIVIANET and MIDI2NET, neither of which are xp friendly but do work on win98 (Just search google). This link has an app for MAC midi sync over lan for anyone interested...

I'm trying to find someone to help me develop a modular virtual midi router app so that you could say use your wireless LAN, USB, or Firwire ports to transmit/receive midi data. Save the cost and bulk of a midi adapter when in an all computer enviroment.

If anyone is knowledable on this please email me.

Trying to send Audio over your ethernet connection is probably not much different than the current Voice Over IP technologies all the big networking companies are trying to create in order to have phone calls go over ethernet.

The problem comes in latency and reliability, just as in all other forms of audio/midi data transfer (audio cards, a/d d/a converters, midi actuation)

CD-quality audio transfers 1,411,200 bits (1.41Mbs) per second (44100 * 16 * 2), so 100Mbps can easily handle multiple channels of audio, even with the expected overhead over ethernet.

Peak Audio has a proprietary protocol for handling audio over ethernet but it's designed for *large-scale* systems.

The best bet for seeing audio flowing from computer to computer with low latency is probably Yamaha's mLAN technology, which is essentially a local area network run over Firewire cables and dedicated to audio and midi data and routing. Hopefully it will catch on and be easy to use. So far it's only in a few mid to high end products, mostly from Yamaha.

I just saw this posting on osxaudio.com. There is a beta version out that does midi over ethernet. Here is the link http://www.osxaudio.com/index.php?story ... f027367eba

I'm gonna give it a try...

has ne1 tried mididvianet on xp yet? it's a long shot but hmm, otherwise this seems like a good thing to build yes???

Check out iMIDI:

Works fine within a 802.11b wireless LAN.

Ive tried MIDIVIANET on XP Pro, it seems to install and says its running once ive set it up. Ive tried changing settings in the MIDI/Sync folder on LIVE , but i dont seem to be able to sync the two computers , so when the BPM changes on one the other stays the same changes etc, Ive tried pressing the external sync button on the slave and it doesnt appear to change anything.

HELP

Will any program work with XP to link up two PCs via LAN?

have you tried musiclab's "midi over lan CP" ?
it works with any software / platform

I use it and it is brilliant.
