When we first set up some kind of studio to record our music, we just put the mic up in front of the computer while recording. A problem then was that it picked up some of the noise from the computer. Later we got a recording booth and that has improved our recordings a lot. One problem though is the distance between the booth and the computer. You have to get in and out to start and stop the recording. Not to mention that the cat also gets in and out. We seldom use the setup with the singer in the booth and the producer by the computer. Rather we record our own vocals and at a later time review it together. So it would be convenient to be able to control the computer from inside the booth.
I started to look for a solution based on the recording software that we use, which is Cubase. The developer do offer an app for iPad to remote control Cubase. First you have to install some additional software on the computer to complete the setup. For me it only partially worked, or hardly even that.
It wasn’t before later when I was working with operating panels for industrial use that I came across a more generic way of remote controlling another computer on a WiFi network or even over the Internet. It’s called VNC and it’s based on a server/client setup. You install the software on your computer and on your mobile device. Since the VNC technique is generic there’s a lot of apps to choose from, like RealVNC and TighVNC. If you’re using a Mac as I happen to be you don’t even have to install anything on the server side. It’s already there since and it’s called Screen Sharing.
