Summary: ScummVM PCJR/Tandy audio differs from actual Tandy 1000 

Initial Comment:
In games that support Tandy sound, certain notes (particularly the low bass line in Zak McKracken and the plinky opening in Maniac Mansion) have different timbre than they sound like on the real hardware. For example, on the real Tandy, the climbing bass line is clearly the same synth note, it just increases in pitch. In ScummVM, the initial, lowest note sounds strange and then as it hits the next pitch it changes back to sounding the same as the real Tandy. 

Since a picture is worth a thousand words, I'd say a sound file should be worth just as many, so I'll just post the comparison recordings. In the recording, it goes scummvm->tandy so the first recording is the weird sound, and the second of each recording is the original hardware. You'll see what I mean.
