I'm going to make my own effector, I assume to use a microprocessor to control FV-1 and control main parametr of effect by platter disc, exactly like in Pioneer effectors (Google: Pioneer FX500 or Pioneer FX1000). I want to add a second parametr to regulation and mix. That's all I can say about my c...

Thanks, I'm testing this soft now. But, unfortunately, I see your last version (#399) has some bugs (for example window with information about max used instructions that is displaying all time and can't close it). Just one more question about programming eeprom - this memory has address inputs A0-A2...

@Digital Larry - I'm talking about this:

Can I download this program from somewhere ?


BTW - is my schematic correct ?

What do you say about this ?



I think, in that way I can connect much more eeproms by adding next gates. Do you think it will work ?

You don't even need a multiplexer, you can connect the SDA and SCLK lines of the eeproms in parallel. The FV-1 talks to the eeprom at address 0, set by pins 2-4 on the eeprom, so your micro just needs to toggle one of those pins on each eeprom setting one to address 0 and the other one to any other...

What do you think about that method (eeprom switching via uC) ?

- If effect is loaded, set S2S1S0 to 000 and T0 to 0 (bypass)
- Switch EEPROM connects by multiplexer
- Set T0 to 1 and S2S1S0 to desired value

@Digital Larry, What's with your SpinCAD Designer ?

No, thanks :) It's not for me bacause I want to pack it all in one chip and, if it's possible, get stereo. BTW - this 1s delay (Fs=32kHz) is for 2 channels (500ms/chan) or 1s/chan ? And another question - about programs memory (external). In one 24LC64 EEPROM I can pack 8 effects. But what if I want...

It was so beauty to be real...
I suppose there is no way to use an external memory too, right ?

Do you know some other dsp processor like fv-1 in similar price ?

Hi. I found here a code of delay effect with 8 seconds delay. I think this processor is amazing that it can do something like that :D But there is a little problem - sound quality is very bad. Frank, you helped me a few times, I think this time you also help. Here's code: equ input reg0 equ loop reg...

I will be something like this ? ;Process Pot2 to decide 1 of 2 output possibilities rdax pot2,1 and %01000000_00000000_00000000 skp zro,LowPass ;if zero, the skip over other code clr ;clear the accumulator NotchOut: ldax notch skp run, Pend ;skip to end of code LowPass: ldax lp_dly skp run, Pend ;sk...

Thanks, I think this is exactly what I need :) Can you tell me what's the difference between 24 and 48bit version ? And I have another question: If this code makes 4-position "switch": ;Process Pot2 to decide 1 of 4 output possibilities rdax pot2,1 and %01100000_00000000_00000000 ;mask off...

Hi,
Is there a way to generate white noise using FV-1 ?
Later I want to add a low pass filter to make something like step noise, but I can't find any program to generate noise.

I have read your advice few times and I was able to properly modify the code at first try. Now it's works like I wanted at the beginning :D I put the modified code below. I use POT1 (center) to control a crushing, and position 0 is bypass. flopper equ reg0 lastval equ reg1 clr rdax flopper,1.0 ;read...

If it's a such big problem for you, what have I to say ? I think that other people will benefit from this too, if you help me with this code. This effect is quite popular. Or maybe is somewhere a complete code ? I think it would be faster if you do it for me than trying to explain it to me, because ...
