−'''a real-time software synthesizer based on the SoundFont 2 specifications.'''
+One of zynthian's primary instrument weapons. It handles sf2 sample files which can contain a range of samples. Fluidsynth itself doesn't have a graphical frontend but it's designed specifically to allow other software to control it remotely which has lead to a range of control surfaces, of which the early use in zynthian demonstrates the flexibility of this approach.
+'''Pianos, organs, strings, harpsichords, marimbas, guitars, bass'''
+So you have access to the many sf2 files that are out there providing ranges of samples to impersonate almost any instrument one could model from a western 12 note scale!
+Most people will simply load up the appropriate files and use them exactly as is and the zynthian parameters

+===Other uses===
+But it doesn't have to be a full range of sounds ...
+For instance I have 8 church bells in a sf2 file allocated to the keys of the F major scale which plays the appropriate sound when pressed.
+There are also some Mellotron & it's antecedents sf2 files out there ( I bought mine) that allow the features like the foxtrot and a lead saxaphone to be played in single finger fashion....
+===Polyphone===
+[https://www.polyphone-soundfonts.com/ Polyphone website]
+If you do wish to get creative with SF2 files then you will arrive very quickly at Polyphone.
+This is a truly wonderful tool for preparing and treating audio samples for use in sound fonts.
+It used to be a bit of a pain to load on a Pi but there is a package in the Pi package manager for it now. There are MAC, Windows versions available from the Download page. Can't recommend this highly enough. Fantastic for soundscape work...
