Hi there, If anyone is using Logic Audio and Acid/Gigastudio on the same PC or Gigastudio/Acid or softsynths on separate PC's and is interested in using midi over a network. Instead of having to buy extra midi interfaces then i suggest you try this!! MIDI Replicator Driver http://www.musiclab.com/products/rpl_info.htm Multi-client MIDI device access Communication between MIDI applications MIDI over network 1) Open more than one MIDI program in Windows 9x/ME/2000/XP! It can share existing single-session MIDI IN and OUT ports between your favorite MIDI programs. 2) Create local MIDI Pipe devices supporting fast MIDI events transfer from MIDI OUT port to MIDI IN port (the feature for example allows to direct MIDI OUT stream from one MIDI sequencer to MIDI IN port of another one). 3) Connect MIDI applications running on several computers connected together via local network. Now you can easily receive/transmit MIDI events from/to remote computers via local network to: synchronize sequencers on several computers; playback music using your sound devices located on different computers in a time; play jam sessions on several computers; record music playing back on remote computer. I have tried the demo and it works very well.You will need 2 programs MIDI Replicator Driver 2.0.2 Demo http://www.musiclab.com/downloads/demo/index.htm#128 MIDI Connection Center 1.1 http://www.musiclab.com/downloads/free/ You have to install Midi Replicator on each computer in the network and Midi Connection centre on your Logic computer.The demo only allows one input and output port but the full version £29! allows up to 10 input and output ports and 2-8 client devices. Cheers Martin B ps I don't work for them!
