gramophone2 binary package in Ubuntu Noble s390x

 GRAMophone is partly based on an idea of Jon McCormack’s, who invented
 the idea of a virtual player (virtual musician). The player in question
 is associated with a MIDI track, and interprets instructions telling it
 what to do. Generally, they say play notes (send MIDI messages).
 GRAMophone’s players together make up an orchestra, which plays a
 composition. Any number of players can play a composition, but in practice
 the hardware used might impose an upper limit. In general every player
 plays an instrument and each has a different set of grammar rules.
 An individual player is characterised by a set of parameters which are
 shared by the whole orchestra and/or a personal parameter set.
