Quality of Sound of instruments and stability/reliability question

[naushad-jamil]

I have just started using this awesome library. I have a couple of basic questions.

1. There are several categories of instrument packs like SplendidGrandPiano, ElectricPiano, Soundfont, Mellotron etc. Each have a collection of instruments. From my quick testing it seems the SplendidGrandPiano and ElectricPiano sounds the best. Can somebody explain me if that is really the case and why so? How are they fundamentally different from other instrument sounds? Higher recording quality, more samples etc.?

2. I have been using SplendindGrandPiano in the app I am building. Often the sound do not come and when I debug I see errors in console some notes cannot be loaded. E.g. M820 can't load. Something like that.

Is this because the sound files are hosted in a server that can't handle load?

If I don't want to self host the sound files and use as is - is there any instrument pack that has more chance of working reliably over others? Say Soundfont because these files are perhaps smaller or something?

Secondly, other than using browser cache (CachedStorage) what is the best way to make sure the sounds will load/play reliably when multiple users are using the app from web?

Thank you.
