Very cool! I think that LDR/LED pitch control was a genius work around. Excited for part two!

Another cool thing about LDR's is that it keeps the systems electrically disconnected. Kind of cool when you want to adjust bigger power things with little power things. :)

I've seen toys where the pitch resistor connects to two pins on the sound chip and ones where it connects Vcc to one sound chip pin. My guess is that in the former case it's coupled with a capacitor to control the clock speed while in the latter it's going to a voltage or really current controlled oscillator for the clock - in that case you can replace Vcc with a variable voltage to change the pitch. But in the former case you really need something acting as a variable resistor, such as your homemade vactrol (or the commercial one I used in my Megamodule). Nice work!

This goes for all transistors in your setup: It is probably wise to use a resistor of e.g. 1kOhm between the transistor's base and the teensy output. Otherwise if you connect them directly the transistor will restrict the base-to-gnd-voltage to 0.6 Volts and the Teensy wants to output 5 V (or is it 3V3) and one of the two might not like the voltage of the other. The 1kOhm resistor will allow for a controlled voltage drop between the teensy and the transistor's base. Geinig projectje, overigens!
