Re: TCDDK on 64-bit OS?

I've been using virtual box per audioartillary's advice and it works great for me. I get my USB connection to work through the devices menu devices/usb devices/ and then i just click on the ToneCore and it gets its act together.

Re: Pitch detection/octave effect

Alright, since MusicalCircuitry already offered some suggestions, I might as well get my 2cents in:

WaveTable lookup (also featured in Hal Chamberlin's book)!

It's super easy! It might take up a little memory, but seriously, not that much. All you need is a single period of a not so low frequency sine wave, say 20Hz. step through it at different rates to increase the frequency.

Re: external memory

thanks for the advice. i've had some more time to look into it more in depth lately. basically my issue was that even with the DMA transferring scheme that they show you in the example code, the destination address is in the y memory. why not use the 'move' instruction? probably cause it wouldn't work. but i can't quite bring myself to experiment with that because i am still going for the delay effect and i have a new problem:

can you use the example code they give in the Line6 manual to read from external memory as well? i'm trouble shooting my code and as far as i can tell, you shouldn't have to tweak the code outside of switching the source and destination addresses. am i mistaken here?

that sounds sweet! i've been wondering about pitch detection as I've been working on my delay effect as well. i learned about some algorithms in a class i took, but the only one i can remember is a double fft algorithm, but that seems like it would take too much time. sounds like you have this zero crossing stuff working well though!

let me know if you need any help with the sine wave generation. i've implemented a sine wave algorithm successfuly before and might be able to offer some good advice.

external memory

support@line6.com — Wed, 13 Apr 2011 03:06:50 GMT

Hi everybody!

I'd really like to get a delay effect online, but I'm having a hard time wrapping my head around using external memory. I see the example in the tonecore Appendix A that programs a DMA transfer for the routine, which I'm pretty sure I'll have to try to understand at some point. The thing that is confusing me is all this buisiness about memory mapping and the pictures in the Freescale manuals that show some of the X and Y space labeled as "External." Is it possible to do external memory transfers by just moving data to the "External" spaces of the X and Y memories?

Thanks ahead of time!

development software

What kind of software does everyone use for developing algorithms? I used to use MATLAB while I was in school and I know about freemat. But does anyone have any other good cheap suggestions?

wow, only took me a month. it worked!! thanks a lot for the idea. virtual box is amazing. after i got xp installed on virtual box i was able to download the developer program and install it no problem. hopefully it won't take me this long to get my first effect up and running. thanks again!

thanks for the suggestion. i'm half way there. had to find a copy of XP to install, but i'll let you know how it works out here soon.

thanks!

64 bit windows 7 support

Hi Everyone,

Does anyone know when Line 6 will support windows 7 64 bit? Are there any current workarounds?
