I need this thing. I need it in my house. Please make more and sell them, I'll gladly pay for the cost of the organ as well as labor to modify it.

Linus,

The reason I did a "mov vscl,#100" while the video generator was reloading on each pixel clock was to hand it a vscl value, which would be grabbed immediately, which would occupy the video shifter until the user-chosen vscl values and waitvid instructions were ready to go in each cog. It just puts the initial important reload 100 pixels out, so there's time for each cog to set its own initial vscl value and get into its own waitvid before it's show-time. I agree there could be some synchronization problem on issuance of the vscl=100, but if that is synchronous across all cogs, all subsequent waitvids should be forever sync'd. It might have been my dumb luck that the FRQ values I was using never got me near a metastability point that could have caused the "mov vscl,#100" to not take across all cogs simultaneously.

Have you witnessed any synchronization problems with any of the multi-cog video drivers that I wrote? I haven't, myself, and I've never heard anyone else say so. I'm just curious.

I really liked that Turbulence demo you wrote. I hope you stay interested in the Propeller, as the next version has perspective-corrected texture mapping with RGB lighting and alpha-blending, all in 8:8:8 RGB. There's also a lot of math hardware for fast transcedentals. You would be able to make it do lots, I know. It has 75-ohm 9-bit DACs on every pin, too, so you get nice video. You can attach an SDRAM for big memory (APA graphics), as well.

Thanks.

In the prose example, White should be green like all the other adjectives. Just saying - being the proofreader I am. http://jcoud.com :)

Just wanted to say I really love your instrument, and please keep on releasing new tunes :-) Have been listening for hours now..
However I have a question to the following reply from you:


Why is the triangle generator your bottleneck? It seems simple enough; just left shift the current waveform counter value by one, and in case of a carry bit, xor the result.

BTW: I would really love to see the code for the synth module :-)

Sorry, I meant invert the result (xor by 1's). - Johnny

This is an interesting analysis. Very intriguing!

I think that the "circular" step-wise motion is an effect, not a cause. I believe that the voices move that way due to the smooth, scalar voice-leading that Part chose; but I do not believe that Part was thinking in the way that you describe: which is to say that the music can certainly be diagrammed in the manner that you describe, but that I do not believe that Part had this scheme in his head when he composed the piece. Certainly, there is a harmonic additive process being employed. But I think that he was thinking in harmony, melody, and voice-leading.

Of course, I don't know that for a fact, and again I don't mean to criticize your analysis--only to point out that perhaps Part was thinking in "math," from which you have distilled an interesting "equation."

Hi Linus,

Thank you for your great contribution to 8-bit music and SID-Chip compositions. If you should ever have any need for webdesign or webprograming just ask, and I'll gladly contribute. :-)

Have downloaded all your compositions and they are now site by site with the Lizardking and some of the other old SID-kings. ;-)

WOW...look at this. I love the chipophone! I visited your site many times, to listen to your tunes and they even made it into my car :) And suddenly there is a wonderful version of one of my favorite melodies.
Thank you so much!!!
