I too would like to be a Beta tester!

Hey Slacker, thanks for the catch! It is outputting now.

I implemented the changes you suggested, but I think I have to take a look at the allpass filter. The effect is now behaving more like a ring modulator, in which the ramp is changing pitch, instead of modulating phase.

Ok, never mind on that last message, I found my mistake. So I got the code to run, but I'm not seeing any output, and I'm not sure why. The code is pasted below. Correct me if I'm wrong, but shouldn't this effectively be using the lfsr register to choose a psuedo random pointer in the delay line cau...

Hi all, I decided to implement the 24 bit lfsr but I'm having an error with the skpzro command, it pops up with an error. I didn't know this OP code and apparently the IDE doesn't either. Any help would be great! ; ; Frank Thomson - OCT Distribution ; V2 of 24-bit ; 2011 ; ; reg 0 : lfsr register ; ...

Sean,

Yes, that step setting on the PH-3 is something like what I am going for.

Thanks for the clarification. I know a good amount about many effects, but phase and flange are relatively new to me.

I'll be attacking the code here after Monday, its finals week

Fantastic, I appreciate all of your guy's help. I'll implement it after finals here this week and I'll send you the results. Thanks again!

Thanks for the help guys! I did a little research and some call it a barberpole flanging like effect. I'm not so sure about that, but it seems a pseudo-random LFO is the way to go. Please see this nice article: http://www.geofex.com/article_folders/lfos/psuedorandom.htm Feel free to lay all the theo...

Hi all, Given the FV-1's efficiency at generating all pass filters and pitch shifting, I was thinking it should be possible to implement the step phase effect on it. I was wondering if anyone had any ideas on how to do this, as I'm lost to how to do it at the moment. Here is a good example of the st...

So I am working on running convolutions in the FV-1. I am pretty sure I can convolve the guitar signal with itself using some short cuts, but convolving with an LFO, it seems I will probably run out of memory. So, would it be possible to have a microcontroller actually run the calculations for me? S...

Whoa, thats cool. Will check out.

Thank you guys!

I am not a big fan of flux so I tend not to use it.

My biggest issue is having solder run over multiple pins. I think I just need a thinner tip.

Ok, so I'm new at soldering these SOICs. Any suggestions?

Thats what I was thinking. Though it still does it when attached to a power supply but the computer is still close. Probably EMF emissions from the compy. Thanks Frank!

Anyone else get a significant amount of noise testing with the development board? Even the built in programs suffer from it. Not a big deal as I will be shielding the actual PCB for the product board, I was just curious
