QBJS Sound Demo

[grymmjack]

Here's a little demo app to show off the SOUND support in QBJS.  Thanks again to @grymmjack for the code contribution!

Thanks for sharing this! 
Pretty neat - I'm hearing polyphony pressing >1 keys simultaneously. 
So has QBJS jumped ahead of QB64PE with audio support? 
(I recall reading that QB64PE's SOUND command would support >1 channels later on, but not yet.)
If so, this would be a practical reason for me to finally jump into QBJS.

I wouldn't say ahead, as it lacks PLAY. Also there are a lot of things in QB64PE that might be missing in QBJS including the ability to play tracker modules, MIDI files, soundfonts, etc.

It's a little closer with SOUND - this mirrors actually (or is inspired by) the changes that @a740g made to SOUND that added waveform types and volume ramps.
