On 1 October 1928, the Capella was chosen by the People's Commissariat for Education to work with bandura specialist Hnat Khotkevych to form a special experimental studio for the development of bandura technique and repertoire. The members switched over to diatonic Kharkiv instruments made by Poltava bandura maker - Hryhory Paliyevetz. The Capella had its name changed to the "Exemplary Bandura Studio of UKRFIL".
