Build Your Own Clone Message Board

I am a computer science grad and know my way around code - but when I took a class on assembly I was thrown through a loop! The more you look at it, the sillier it seems, but I guess that's how machines know what to do haha. All I can be is thankful that we have Java, C++, etc, etc. to make coding readable

^^ I may well be calling on you to help figure stuff out. But I agree that assembly is a different beast altogether. They don't call it "bare metal" for nothing.

Yeah have to agree with you, I do almost all my programming in C then compile into assembly language. Im just lazy I suppose. MCUs can be fun be also VERY frustrating at the same time. If you are ever interested in a PIC programmer, I got you covered! Would let it go for VERY cheap. Older version of: http://store.melabs.com/prod/u2/U2BUN.html

PICbasic is also a pretty easy assembler to use.

For sure CJ, I'd be glad to help!

So i made a comment goofing around earlier inthis thread.
but now im curious... could this be programmed to work as an infinite reverb?
And if so, would it be possible to use it for more than just that on one board?
Like a freeze, multi reverb, and delay type thing?

I'm not sure if infinite reverb is possible, but I suspect that it is.

The FV-1 can access up to 8 different programs on a ROM chip, so multiple effects in one build is absolutely possible.

This wouldn't happen to be the cryptic "tigerlily" build that Bean has on the board list?
-P

I don't think so.

So far this has only been worked on as a collaborative type project. CJ obviously has taken a big interest in exploring the programming aspect of it and I'm definitely open to taking the ideas as far as we can. This little prototype is just a simple in/out wrapper with the digital stuff crammed in there....mostly to test it out and see what it's like to work with. As he mentioned, the reverbs are pretty nice and the pitch shift is great but too limited in the canned chip. The flanger pretty much blows on it...no comparison to a true analog flanger, IMO. Maybe it'll grow on me.

Anyway, hopefully there will be some more to show down the line. Like the man said, it's gonna be a while.

True dat!

It's a totally different world to do this stuff in the digital universe. I barely understand what is happening in the analog realm, and now I'm going have to think about how to emulate it with code. It's pretty daunting, but the challenge of it is appealing to me. And also, there is some fantastic open-source code already available that we can use as a jumping-off point and a pretty decent (if very slow) forum where questions actually get answered. For example, all of the built-in programs on the FV-1 have their code available. Right away, I will start with a few of those and see what happens. And there are some other cool effects available as well, including some plate reverbs, pitch shifters, EQ, and compression. So just about every effect type is available right away to mess around with.

Another note you guys be interested in is that the internal memory is big enough to run a full 1 second of delay time at 15Khz (plenty good enough for human hearing ranges). So I plan to throw a lot of my effort into various flavors of delay, as I'm sure none of you will be surprised to hear. I really want to do a delay with modulation, but using flanger or phaser modulation instead of the typical chorus/vibe. I'm not 100% sure it's possible with the FV-1, but I don't see why not.

Anyway, I'll give you guys more details once I have the dev board set up.

Youse guys is the smarts.

Dan man, can you tweak all those to have flanged verb, or chorused verb, like only on the verb signal or no it has to be like Holy Stain?

Eh, I know all those words, but I don't understand them in the way you've got them arranged.

You can pretty much do anything. The limitations are the amount of memory you have to work with. More effects = more memory, so you can only do so much. As you pack more stuff in, you start losing audio quality (or plain just run out of room).

But the Holy Stain merely accesses some of the built-in demo programs that ship on every single FV-1. Same as the project that madbean did the board for. What I and bean will be working on now is creating new effects programs to load on the FV-1. So yeah, we could do a flanged reverb. Or a phased delay.

I'm actually pretty sure all the new stuff coming out of Earthquaker Devices uses the FV-1.

Wow! Wayyyy to cool!

Awwww hell. Dev board is in full effect. Did some basic testing and it's operating just fine.

It's got RCA jacks for input and output, so I rigged up some RCA-to-1/4" jack converters using shielded wire.

Next step is to put together the wet/dry mixing circuit. Should be a simple affair. Then I'll box it all up a little more formal.

Awesome Man!! Really happy for you!

WoW! incredible, new realms of DIY!

Where do you source the FV-1, and whats the damage??

Smallbear has them:

For 18 bukkakes you get the crystal too, cool

Don't forget to pick up a 3.3v regulator as well. Smallbear suggests the larger kind with a heat sink, but madbean's board uses the small plastic type.


Salty Romance Explosion!!!

Or bromance?!
Hehe, I'm good at waiting, so I have no rush chipping up yet
