The sound of Japanese strings is both captivating and highly unique. What makes it so distinctive? Smaller ensembles recorded in focused studio spaces lend themselves to more agile playing, and a focus on perfection leads to incredible accuracy. These strengths make Japanese ensembles equally capable of delicate nuance and sweeping emotional performances that move listeners to tears. For many of us who have admired Japanese soundtracks for years, this sound has long been a source of inspiration, but it’s been out of reach for most composers outside of Japan — until now.

Our goal with Tokyo Scoring Strings is to give you the orchestral string sound featured in so many world-famous Japanese productions. This project has been a dream come true for all of us at Impact Soundworks, and we’re thrilled to have worked with some of our musical heroes to bring it to life. But we weren’t satisfied with just capturing this remarkable sound; we also sought to deliver an outstanding, inspiring UI, flexible editing, beautiful legato, and recording depth to rival any other industry-standard string libraries.

Our Japanese Partners

We are honored to have partnered with an incredible team of musicians and collaborators in Japan:

  • Koichiro Muroya Strings, led by Koichiro Muroya. The most in-demand session ensemble in all of Japan. Their exquisite playing can be heard on many of your favorite soundtracks.
  • Mitsunori Aizawa, Japan’s top engineer, responsible for mixing and recording hundreds of world-famous scores.
  • Sound City, an incredible recording space with over 60 years of history. This choice of studio gives Tokyo Scoring Strings a tighter, more focused sound that lends itself extremely well to more agile playing and mixing with external reverb.
  • Renowned anime & film composer Masaru Yokoyama, who brought his experience recording scores around the world through his companies Plugnote and MiracleBus.
  • Crypton Future Media and SonicWire, our Japanese distributors who have helped with the project from the very beginning.

Tokyo Scoring Strings features five independently recorded sections (Violins 1, Violins 2, Viola, Cello, Bass) in a typical Japanese ensemble size (8/6/4/4/3) suitable for small and large productions alike.

Tokyo Studio Strings includes a well-rounded set of articulations recorded in superb detail. We have paid particular attention to delivering outstanding legato as well as the agility and crisp short notes that are such a strength of smaller Japanese string sections. You’ll be able to easily write and mock-up sweeping melodies, intimate legato, and aggressive agile passages.

Note: All articulations below are true, unique recordings, not created by re-pitching or processing other samples!

Console: Modular FX Rack and Mixer

Console is a fully-featured mixer, modular effects rack, and pedal board, designed to give you full control over your mix. Effects include multiple EQs (digital and analog-style), compressors, spatial FX, modulation FX, amps, distortion pedals, reverbs, and more.

Each mic channel can be loaded with up to 8 FX in any order, plus another 8 slots on the master channel, with support for send routing as well. The new “Galois Reverb” added in Kontakt 6 Player sounds fantastic as an alternative to our included custom IRs.

Testimonial – Hiroyuki Sawano (Attack on Titan, Kill La Kill, Seven Deadly Sins)

“I was curious about TSS because my work friends, Mr. Muroya and Mr. Aizawa were involved in the project. It was recorded in a studio that I often use for my string recording. I have enjoyed using this library as its sound presence and moderate ambience is unique and different compared to overseas recorded libraries that I usually use. I think it can be used effectively in a wide range of genres, not only for epic sounds, but also for rock, pop and dance music.”

Testimonial – Yasunori Nishiki (Octopath Traveler)

“It sounds exactly like what I’m used to hearing, Muroya Strings x Sound City x Mitsunori Aizawa! The staccato and pizzicato reverberation in particular gave me a sense of Sound City’s unique reverb, and I felt like I was in the Sound City control room. The sound definitely has the sense of Japanese strings and studio, making it easy to use for any kind of music. I believe this library delivers the sound of Japan to the world!”

Testimonial – Satoru Kosaki (Lucky Star, Monogatari, Beastars)

“I feel proud that a library made by close representative members of the Japanese soundtrack industry will be released. I played back MIDI data from one of my past compositions which was eventually recorded with the exact same team, and it sounded astonishingly similar. I was also impressed by how easily I was able to produce their sound without having to adjust or mix any details such as the space size, instrument balance, and legato speed, etc. I would absolutely recommend this library to anyone who wants to replicate the sound of Japanese soundtracks, and personally, I feel it will prove to be crucial in my arrangement process as it will be so much easier to imagine the final recorded result.”

Tokyo Scoring Strings – Kevin Kuschel

“But when it comes to smaller section-sized string libraries with a great legato, TSS has become a valid, new contender here that also brings a whole lot of workflow power to the table. If you want that JRPG tone with a smaller, focused ensemble size, for telling musical stories in a big context, then TSS is for you.”

Kevin Kuschel (12/21)

Tokyo Scoring Strings – StrongMocha

“Tokyo Scoring Strings is the answer to any composer’s dreams of having a world-class strings library in their arsenal. It’s also perfect for those who’ve never used such an instrument before because it has everything from deep-sampled playing techniques and expressive scripting that will take care of all the work of creating the perfect sound for you…not limited to just movie soundtracks or anime themes, as they could also fit well with anything from jazz, rock & roll, or even heavy metal!…The library is so much more than I ever could’ve imagined. It does seem like a magical palace, and it’s perfect for people who love to compose and produce.” (5/5 stars)
