Re: [xl7] Any interest remaining in a self-programming FLASH SIMM?

2014-07-15 by janoch23@...

I only suggested dynamically modified samples, half jokingly, to get "global single-lfo rectangular pwm" and true noise say at waveforms #126 and #127. However, with 128 MB of sample ROM, you are much better off simply using samples for those, and not worrying about some clever scheme in the address decoder.

With regards to the micro on the SIMM, I think the other view is that having an SD card slot and figuring out the data format would be more useful since SD cards are cheap and abundant, and you'd have automatic compatibility with all kinds of PC operating systems via the ubiquitous card reader. This view doesn't really hold though because you'd be forced to open up your p2k / cs every time to pull out the SD card.

Personally I'd also worry that figuring out the data format is not simple at all and you'd risk having the project die out while people spend years trying to reverse engineer it, never fully figuring out every detail.

With your (Jack Pratt's) design at least everybody could duplicate existing ROMs and have something very useful "out of the box". Seeing how designing a large waveset is no mean feat, that would probably be the most useful.

The best way to do this (IMO) is to have a micro on the SIMM that will allow the FLASH to be 'reprogrammed' via USB. With appropriate software any image (existing or composed) could be transferred to the SIMM.

Finally the logic device can be used to provide access to on-the-fly sounds. However there are plenty of limitations to this.
