Vocaltract on Hydra? Probably asked before.
Can anyone point me to a clue how to run and hear the "seven" or "monks" demo on Hydra?
(and then tinker with the vocaltract)
I tried probing pins with an audio amp looking for the sound. Maybe I missed it.
What else is different in the program besides the sound output,
and can it be edited to work? I just started to tinker with it so it may be
a while before I figure it out alone.
Also, I have "software speech synthesizer" development experience from the 1980's and 1990's.

Comments
I've attached the files source and binaries for Hybrid and Hydra.

I was able to make it less noisy by finding a bug that doesn't turn off the voices between measures
(somehow resulting in background white noise) ... a vtract[noparse][[/noparse]state]:=0 instead of ~ seemed to help a lot.
And also by changing the echo constant to 000_100_000_000 it got even less noisy.
And when I tried to change the formants to higher ones like "oo" and "ee",
it got distorted so I had to comment out one of the four voices. Still a tiny whisper of noise though.
The noise is not heard in the demo mp3's.
Maybe the stereospatializer and clock speed are a problem on the hydra;
maybe I just need an EQ on my speakers.
Maybe I'll compare the proto and hybrid code to the hydra code for clues.
Sorry, just talking to myself.
The vocaltract has awesome potential. I want to sing a song with it.
If I write anything good on it I'll post it. Thanks again.
And it does have lots of potential.
Try pointing one of the output's to the debug LED, it might be because both channels are going to the same pin.
I'm getting the noise too. I can't find "vtract[noparse][[/noparse]state]" anywhere though. Which file is it in?
By changing it, the program sings forever instead of ending with endless noise.
I downloaded the SEVEN demo ... of course it was silent.
I Changed the stereospatializer parameter from 11 and 10 to 7 and 0. Noise gone in either demo.
This apparently means that the sound will come out of just "Pin 7" instead of 10 and 11.
Before that I made it two 7's, that makes noise. (7,-1,0,-1 = nice 7,-1,7,-1 = yuck!)
...babbling on about it...
The "knobs" parameter above that represents an echo delay line and can be left alone.
Setting "knobs" to all 000_000_000_000 sounds "ok",
but all ones sounds like many rodents trapped in a grand piano.
I also changed the CONstants to xtal1+pll8x and 10_000_000 for the crystal timing for Hydra.
SevenDemo is interesting for trying to make it sing something else...
so far like "never seven heaven", based on obvious comments in the source.
It sounds like untrained People singing if you lower the vibrato rate moderately.
Lower it too much and it sounds Robotic but still a little better than Speak n' Spell.
(I only tried that in the other demo given a few comments above, haven't yet found it in the Seven source)
Thanks for the update. [noparse]:)[/noparse]
