SF2 NRPN implementation test files

[spessasus]

Hi,
So fluidsynth supports the SF2 NRPN implementation and I'd like to add support for it to my own synth too, but I've never seen a MIDI file that uses those. If anyone has some test files that use that functionality (for example, back from when this feature was being worked on) I'd really appreciate it!

(For the record, I have never seen such files. IMO, there is a portability problem which originates in the design of the NRPN: it's additive to the default generator value written in the Soundfont's instrument / preset. I.e. if you're a composer and used NRPN in your MIDI, it would only work for a particular (sets of) Soundfont(s).)

I made a test for AWE32 filter cutoff and filter Q NRPNs, available here. There is also a lot of information and some useful test files contained in bug report #1473.

Thanks, but while this is useful for implementing AWE32 NPRNs, I meant the SF2 NRPN's (section 9.6 of the soundfont specification)

I don't have any such tests, unfortunately, and no time to make them at the moment.
