SynthModules

I've started to program my SpeakJet through my PSIM.  I've uploaded
photos of the completed module to the Photos section in the folder
"DJB PSIM-1 (MOTM format)".  I've also uploaded a couple of SpeakJet
programs to the new Speakjet folder.

One program passes data to the SpeakJet through the PSIM so I can run
the PhraseALator program on the PC.

The second program speaks various phrases selected by a control
voltage.

I've got a third program that babbles allophones with range and
offset controls but it doesn't work quite right.  It does, however,
produce some interesting output.
