I still don't know how to do the code or really understand how it works in any deep way but I've managed to make myself a killer high gain distortion patch... I actually really like the digital distortion, it even sounds great at low gain I think, clips in a cool way.



It's the development board for the Spin FV-1 micro plus some analog circuitry to interface it... relay switching, buffer in, split for clean mix, wet goes into the FV-1, back out to analog 3 band eq like the Elements/Cleanness, volume, output buffer.

The Spin is a really neat chip, really powerful. It's designed to do any type of audio effect from delay to reverb to modulation to pitch shifting to compression/expansion to filter/eq to you name it, in stereo. You get 8 banks or patches to work with, stored on an external memory chip, that's the 8DIP beside the Spin. You don't need that whole board for a pedal as it contains the USB interface etc, all you need is what's outlined in the white box.. the Spin chip itself, the external memory, and a small bit of components to set up the chip.

I still don't know how to do the code but it's set up in a way that analog guys like me can get into it... so I'm getting into it! I love all the time based and modulation stuff and will be going there one day, but for now, I wanna goof around with digital distortion/fuzz. It's easiest, it's fun, and nobody else is doing that with this Spin chip.

With the right external crystal for the clock you can even get up to 2 seconds of delay time, so that's pretty cool too... just has a whole bunch of interesting possibilities inside of it and I think rather than take on another huge analog project, I'd like to learn some new tricks and have some fun with this thing.

That sounds awesome Ryan! Digital distortion IS rad isn't it?? Something about it that's just so neat. I'll be excited to see where you run with it!

Yeah, the end result of the Dr. Scientist Spin FV-1 experiments should be super cool to say the VERY least. Ima keep a close on on these scientific developments....

How about a quick demo vid to let us anti-nerds know what you're talking about?

Can't wait to hear what you come up with

I never saw myself needing a distortion pedal, but somehow I will if this happens.
Can't wait to hear how it turns out!

Ryan,

Feel free to get in touch if you ever need a consult on code.. I can probably puzzle through it at the very least (I code professsionally..)

very cool! I was about to order myself the dev board as well. Do you know if you can do the same Crystal trick that you use on the RRR with the Spin chip?

Music to my ears.

BRING IT

Yep... this!!!

What an offer, thank you! *starts packing for month long stay at Mathias' house*

I've made some good progress, haven't really had much time with it but I sneak in a few hours on the weekend... so far I have a great high gain distortion with noise gate. Digital pots control the gain and the gate threshold. Still have one pot to utilize.. I'm trying to learn a sustain program.

The code is actually pretty understandable given how many examples and suggestions the Spin people provide. I'm not saying I understand it, but I get what I'm doing so far, with all their help.

It's just a really fun way to experiment.. typing in changes to the programmer, hit build, test it one second later, I like it.

Yep, the crystal sets the sample rate which sets the resolution and maximum delay time. I think you can get up to 2 seconds of delay at low res.

My goal for this is to make 8 distortion patches, maybe not in stereo at first, maybe just 8 cool digital distortion sounds.. maybe extreme filtering, maybe some octave up or down, I'm not sure yet, but I'm definitely liking the distortion sounds so far.

do you know how the stereo coding work? is the a 2nd set of code for the 2nd channel, or are they handled simultaneously, or?

It would funny if Dr. Scientist suddenly became the next Copilot FX and built really wacky and cool noise-makers. I'd still be a fanboi.

You have to do left and right separately but it's easy, you just read from the left and right ADCs, do the code for each side, then write to the left and right DACs.

I should go spend a month in the Dominican with Adam... get weird with it...
