Description
Hi,
I've found a bug in Neothesia's builtin synth.
The bug
Using the built-in synthesizer, interrupting the playback mid-way does not seem to properly reset the registered Parameter Numbers.
For example using RPN coarse tuning results in the next MIDI file being detuned.
Reproduction steps
I'm using the Flatpak version.
- Make sure that "Buildin Synth" is enabled. The soundfont shouldn't matter.
- Play
test-rpn-00-02-coarse-tuning.midand press escape on the 7th note. - Play
test-c-major-scale.midand hear the detune. - Restart Neothesia and play
test-c-major-scale.midagain. The tuning is correct this time.
If this is oxisynth's fault and not Neothesia forgetting an RPN reset, then I'll post the bug there too.

Research direction
Start by reproducing the problem with test-rpn-00-02-coarse-tuning.mid and test-c-major-scale.mid while the built-in synthesizer is enabled, interrupting playback on the seventh note. Trace the built-in synthesizer's playback interruption and RPN state handling; done means the second MIDI file plays in correct tuning without restarting Neothesia.
