Some of its instruments include a tenor flute, a G soprano flute, grenaditte flutes and a new C flute design called a Tocco flute.

Contrabass flute by the International soloist Matthias Ziegler, for multiple Low Flutes and orchestra. Numerous composers have written for the contrabass flute, including Wil Offermans, Robert Dick, Thomas Seelig, Andrew Downes, Catherine McMichael, and Günter Steinke, to name only a few. Furthermore, the contrabass flute is being utilized more in the flute choir with most newer pieces including a part for the instrument. Though for many pieces, the part is either a duplicate or simplification of the bass flute part, some of the newest repertoire includes an independent contrabass flute part. Composers of such pieces include Peter Senchuk, Toby Caplan-Stonefield, Lawrence Ink,
