There are a few instruments available, but they have some caveats to keep in mind:

• Mandolin (GDAE)- this will be the default instrument as that's what I practice most
• Ukulele (GCEA)- tabs for ukulele are still something I'm trying to get my head around as there's several options for each note, and I'm not sure which ones are the best. which is why you will see the options like this

• Bağlama (Saz) (A2A3 G3G3 D3D4D4 -19 frets) - still figuring this out, frets and tuning seem to vary quite a bit, but the tabs should be for the most common layout (I hope?)
• 4 hole ocarina is in C
• 6 hole ocarina is in C
• 12 hole ocarina is in C
• Recorder is in C, + sign marks the thumb hole
• Whistle is in D, + sign means upper octave
• Hurdy Gurdy is in G - I didn't add anything about drone strings and trumpet strings because I've not yet figured those out
• ABC - I use this for melodica, not sure if it's useful for anyone else but it's there
• Kalimba - set up for a 17 note instrument with the lowest note in C

Instruments in a different tuning can have their tabs show by transposing the music, which isn't ideal. If you want a specific instrument added get in touch and I'll see what I can do.

Transposing is done via semitones and the tabs should try to fit themselves into whatever instrument is selected by transposing the entire tune. If you don't want the entire thing transposed because of one or two wayward notes, you can squish everything into place:
