Hi again, I thought I should make this a new topic. Thank you all for your help and advice on my other topic, very grateful. I enjoy doing jingles and background music, and would like some advice as to what radio stations, advertising companies, Tv commercials, need for demos, for example, would the demos have to be mono capable, normalised to 0db, etc. I hope, eventually, after much learning from you guys to be able to, maybe someday, to send some demos to the above! Much advice needed. Many thanks for your patience. Allan.
