Spin Semiconductor

Cool, glad I could help. I'll just take 5% of your profits as a consultant's fee.

So, I tried something like this but I'm pretty stuck at this point since It really does nothing: ______________________________ fil equ reg0 inverse equ reg1 rdax adcl,1.0 ABSA RDFX fil,1 WRLX fil,1 SOF -1,0.999 wrax inverse ,0 rdax adcl,1.0 ; Read ADC left mulx inverse wrax dacl,0 ; write to DAC l...

Maybe sometime you can help me with AVRs...

Ok, so I tried to incorporate the dry volume, but now all I get is unaffected signal. Here is some code: equ effect reg14 ; Setting up register ;Processing rda del1+2630, .5 ;sum outputs as taps from reverb ring rda del2+1943, .7 rda del3+3200, 1 rda del4+4016, 1.5 wrax dacl, 0.0 ; Note, the increa...

No problem. I've only been at this for a couple of months, so after asking a ton of questions here, I'm happy to be able to answer one or two.

You should post your code, so we can see what you're doing exactly. But you don't need to save the original to a register, you can just read it again at the end, like: rdax adcr,1 ;read input ;do some stuff, generate effected signal mulx pot0 ;volume for effect wrax effect,0 ;create effect register,...

If you search the forum for envelope detection (or check out the Knowledge Base on the main site) you'll see some code examples to find the input envelope. Once you have that you can use something like SOF 1.9,-1 to make the envelope go from -1 to 1, then use SKP NEG to find when the input goes abov...

:D In all seriousness, Frank, I'd be willing to pay a chunk more than the price of the FV-1 for some upgraded features. I wouldn't expect anything quite as deluxe as the above, but just more expandability in terms of memory, a few more pot inputs or some kind of modularity with pot inputs, and faste...

Would the low frequency response be changed using a 32k crystal?

I guess the question would be: at what frequency does the chip's internal highpass filter begin? Could you even get a 10hz signal into the input? What do you think about this, Frank? I don't think it's a great idea to put a control signal on the same input as audio, but it would be useful to know w...

Definitely possible, but delay time for the delay section will be limited since some has to be allocated for the reverb and flanger. The basic idea of chaining effects in the FV-1 is to do the first effect, put it to the input of the next one, etc. It's pretty simple. Or if you want parallel effects...

Why don't you post the reverb you want to use and we can point out where in that program the pitch shifter should go.

I guess the question would be: at what frequency does the chip's internal highpass filter begin? Could you even get a 10hz signal into the input? You might also have some issue with banging against the supply rails, I would think. If you have a 10hz signal and your audio signal, I think you very wel...

Don, I had a chance to try your algo. First, your second equate statement: ;equ lpin reg1 ; filtered input has a semicolon in front of it which needs to be deleted for things to work right. As can be expected of this kind of thing, the tracking on a bass isn't great. Tracking a bass is notoriously d...

2 excellent posts, lots to digest. Thanks guys!
