  • The next generation of string legatos

    Infuse your music with more passion than ever before with the best-sounding, most alive string legato sound available today. Ushering in the next generation of highly-detailed string legatos, Spitfire Appassionata Strings has been recorded using our new "Impulse Legato" technique – the culmination of years of intensive research and development at Spitfire Audio HQ. Delivering flowing and emotive lines, these new legatos offer perfectly balanced vibrato, enabling composers to intuitively write in a beautiful, soaring melodic style in stunning detail.

    Referencing the aesthetic of classic melodies from the scores of composers like John Williams and Thomas Newman, this medium-sized string band (8,6,6,6,4) delivers a highly sought-after style of performance, with stunningly-realistic rebowing. Crafted from years of sampling experience, Spitfire Appassionata Strings is your ultimate companion for writing with intention, emotion and – most of all – passion.

    Crafted from years of experience

    The legatos found inside Spitfire Appassionata Strings are the result of 15 years of research and development, from our earliest bespoke instruments right through to today. This library benefits from and is informed by those years of learning and expertise, a time in which Spitfire Audio have been crafting samples, creating a custom UI, collaborating with AIR Studios and fine tuning the process of capturing the intensity of a performance, through hours of research and development and attention to detail, culminating in a market leading finished product.

    How does your dedicated plugin work?

    Our dedicated plugin libraries work as standalone instruments in your DAW, meaning that no serial number is provided and the authorisation process happens during your download. We provide an AU, VST2, VST3 and an AAX, so as long as your chosen DAW supports one of those plugin formats, you’re good to go.
