This MIDI stuff is pretty good isn't it.

You can also get Guitar Pro to change the channels on your VH4 via MIDI, so you can play and have the channels change at the correct point in the song :)

How?  :)

Come on Oli, give a nice long explanation, I want to hear too.

Well, if you take a look through a small tutorial i made on it a while back: http://oli.doom-metal.com/midipipe/. If you're not using a Mac, then you'll have to grab the MIXI-OX utility that Muttley posted. Basically, what we do is: Create an additional track in GP, to which you program in when you want the channel/patch changes to occur, and what the patch will change to. By putting the correct settings into GP, it will output that data through the MIDI interface, however.... GP only transmits Note changes, and almost all MIDI capable units use either CC (control change) or PC (program change) messages. That's where that other utility comes in, to perform a transformation, so that even though GP outputs the note message, what comes out of the interface is the CC or PC message.

It sounds more complicated than it is really! I've put up a sample file here, so you can see what information has been written into the 'amp control' track. You'll see values for 2, 1 and 5 in there, and these correspond to the patches in my rig:
1 = Rhythm Distortion
2 = Clean w/chorus
5 = Lead

I'm not sure what the MIDI setup is with the VH4, but it shouldn't be anything too complicated (or too dissimilar to what i explain on the tutorial page).

It may take you a little bit of time to get it working, but once it is, it's very easy to continue (each new GP tab you want to play along to just needs that extra track, and the info for when to change).

If you get stuck, give us a shout, and i'll try and help :)

Once you get into this area it seems limitless. Look at this software and hardware controller from Native Instruments.

I've been drooling and dreaming over this. I've just got to get all my gear communicating or get a new PC or Mac.

MIDIs great when it works, but it can be a massive headache when it doesn't

[sgmypod]

yeah when two or 3 midi devices start interfering with each other

I been using MIDI for a while and find that unless you've got good sounds like reason or good plugins and effects its really horrible.

Ok, question for the crowd.

I'm using Guitar Pro to control the 670, however, the sounds are not as good as the in built drum sounds of the 670, how can I make GP play the instrument sets of the 670? Is it possible, or will GP always override the in built effects?

Not too sure but I'm assuming your using this all through a DAW of some sort. Route audio back into your Soundcard via the audio outs of the external midi unit. On the patchmix program put a send to ASIO on the strip where the audio from your 670 is. You may have to put a compressor above the send and boost the signal up.
