Changes in VST parameters reset to defaults when generating audio from MIDI about pedalboard HOT 2 CLOSED

I see there is a floating-point precision problem because when I input -12.0, it saves it as -12.03 but it seems to be unrelated because I also tried changing the osc1_amp value (where both the direct parameter modification and the editor changes output the same exact value) and the problem persists

from pedalboard.

Just saw there is a reset flag that resets the internal state of the plugin before the instrument generates the sample. It seems that the editor bypasses that reset somehow.

If I change the code to

audio = instrument(
    [Message("note_on", note=60), Message("note_off", note=60, time=5)],
    duration=5,  # seconds
    sample_rate=sample_rate,
    reset=False
)

The problem is solved.

I'm closing the issue and leaving this as documentation in case someone has the same issue.
