Title: PetSynth for the PET 4032
Post by: RobertB on October 03, 2010, 02:37 PM

     How did I miss this one?  PetSynth, the first GPL playable synthesizer for the Commodore PET computer, has been released.  Specifically, it is a program that turns your PET 4032 into a musical instrument with the "finest in 1-bit sound".  PetSynth performs its magic on a stock PET 4032 computer.  For more information on PetSynth and to download the program (or to download the demo song), go to

          http://petsynth.org (http://petsynth.org)

For more information on PetSynth's developer, go to

          To be demonstrated at a future FCUG meeting,

Awesome!  I don't own a PET, but being able to play 1-bit audios sounds pretty cool... I would say pun not intented, but I think that is exactly what my subconcious wanted!

Normally I wouldn't post an irrelevant comment like this, but it just so happens that today I started work again on Media Player 128... so good timing...

I know how harsh 1-bit audio can sound cuz I did some of that back in the day on my C128.  But it is still cool to hear these machines, never designed for PCM audio, to be able play them.

Make sure you select a PET with the piezo element. Otherwise you won't get any sound at all without hacking it. I believe the cut-off is between old style 2001N/3000/4000 boards and new style universal 4000/8000 boards, of which the latter also may exist in different editions. For example my last, remaining 4032 doesn't chirp on power on but works otherwise. I understand with the help of internal or external modifications, even those slightly older models can be made to produce sound.
