For a wavetable intrument (pti) a preview would technically already have the settings, that would apply for all types of instruments, unless it changed recently they always play the sample right?
But that’s probably a different wish then, more of an Instrument Preview Mode (maybe there’s even already a wish for that?)
Are we talking specifically about raw samples that are wavetables? Or both those and wavetable instruments?
Another thought, would it be OK to dedicate Shift + Preview to wavetable preview? Where if we want other preview modes, for instance granualar preview? Should it instead be an Advanced Preview Mode with different options?
