I would ∗highly∗ recommend against putting any signal into the TTL serial
input pin that isn't a serial interface from either a PC or microcontroller
that is actually sending ∗correct∗ communication to the chip. Reason
being... you will most likely really mess up your chip. Just don't do it.
The other input pins you referred to can be programmed for sounds and
triggered to play on both a high AND low signals. To get ∗true∗ analog
Voltage Control over the SpeakJet requires something like... say... well,
the only module in existence that will do it... the SynthModules PSIM-1.
