According to Hungarian-American piper and pipe-maker Ferenc Tobak (*ca. 1945), this is "an old name for the Hungarian Duda in Moldavia (RO)", where it is pronounced Sip [i.e. without the acute "í"]; NB: I wonder if the Romanian (Moldavian) spelling would be Şip, which would correspond with the Hungarian pronunciation (in Hungarian orthography the Latin letter "S" is pronounced like the Slavic "Š" (IPA: ʃ ), whereas the sound of the Latin "S" is represented in Hungarian by the digraph "SZ".
