I have spent a lot of time lately trying to improve my midi-performance and mixing skills, Also I was trying to decide which libraries I wanted to use for my own compositions. I own lots and lots of sample libraries. It has been fun to try them all out, but I realize it has taken away from compositing time. I am NOT a keyboard player, and never have been. So keyboard playability is of zero importance to me. So my choices may not work for you. This midi-performance uses a separate instrument for each part. I tried to match the sound quality of the recording by the London Symphony Orchestra. All VSL libraries are full libraries. Woodwinds - All VSL Flute I, Flute II, Oboe I, Oboe II, Clarinet I, Clarinet II, Bassoon I, Bassoon II Brass - All VSL Dimension Brass 4 horns, 2 trumpets, 2 trombones, VSL Bass Trombone. Timpani - VSL Strings - VSL plus Spitfire VSL Orchestral Strings, VSL Chamber Strings, VSL Synchron Strings and Spitfire Symphonic Strings Spatialization MIR Pro - Teldex + Miracle Additional reverb for brass and timpani Altiverb 20th Century Fox Soundstage. I would have thought that using four different rooms; Teldex, Synchron, Air Lyndhurst and 20th Century would end up a mess. But I am really very happy with the result. I think the complexity added to the sound by the different rooms actually helps it sound more realistic. I look forward to your comments.
