Hi everybody, first of all I want to thank for all the information. I think all the tips are great and will help to deal with reference tracks.
I’ve an absolute minimalistic setup. It’s the DAW, some analog synth stuff, and a MPC. For monitoring, I’ve to work with my studio headphone (closed) and a second one (open) for comparing mixes. My interface has just one line input – but a big volume knob which is very nice in practice. Yes, it is a bad idea to mix without monitor speakers. But I don’t have the space for a bigger setup (WAF) and I decided that mixing with headphones is better than making no music at all. In this situation a reference track is really helpful.
Tonight I will check the plug-ins you recommended. Using external sources sounds promising, but I’ve to upgrade to a reasonable interface (io) first. I will do some notes about my experiences, because it seems to be a typical rookie challenge and some information could help others, too.
