Inside the Prophet '08

More images here via Stephen Jones and a shot of the voice boards here (zip of three here) via Cikira.

Update: Note the Sequential Circuits badge on this second bottom shot. No doubt, via synthwood.

  1. Is that a fatar keyboard assembly? Anyone know if those are Freescale DSPs?

  2. Forget the question about the DSP. Is looks like he's using a Microchip PIC for the digital oscillators.

  3. yah, i think its a microchip simply because he is using those RJ connectors which microchip uses for JTAG debugging (i know the "hockey puck" programmer has RJ cables)

  4. how come somany of teh traces are freehand and funny angles? Usually you lay out with 45 degree wire bends, curve wire bends, or a combination of both. There's some weird freehand point to point stuff there.

    Which digital oscillators?

  6. What's up with the sides of the TR-808?

  7. RE: 808 .. They're being used as templates to make wood replacements.

    I've got a patch I've come up with for the P '08 and I'll upload an mp3 of what it sounds like. Makes use of all 4 LFOs.

  9. Wow That looks almost exactly like my Sequential Multi-track inside.

    Weird.

  10. What's up with the sequential circuits logo?

  11. Hey Stephen ,cool from you to have take shots from the inside.

    are dsi use the same ic's as the custom analog ic's made for the andromeda?

    Sombody should open a andromeda and compare...

  12. What's with the odd order of voice labeling on the voice boards?

    1 - 2 - 3 - 4 - 7 - 8 - 5 - 6

    Just seems strange, but there must be some reason for it.

  13. The Andromeda A6 uses custom ASICs that are designed by and proprietary to Alesis.

    "Which digital oscillators"

    Sorry I meant digitally controlled oscillators. I know they're analog, but I think he's using the PIC micro for the digital control. Perhaps the envelopes are also implemented in the PIC micro as well.

    eww, I hope not.

  15. you're so racist to think a dsPIC can't do an ADSR or two in addition to digitally controlling the oscillator and generating lfo, modulations, etc. Of course, the envelopes are done in the dsPIC. do you see anything else?

  16. I agree. Nothing wrong with digital oscillator controll, envelopes and modulation. The sound of the Prophet 08 speaks for itself.
