Quick update before going to bed..... The formula works as expected, and everything fine. But it took me 2 hours of dumb troubleshooting because it was not working initially... and the failure was that I copy-pasted some code and did not check that the registers were duplicated (stupid me). So, the ...

Ok, I understand what I came up with is a variation of the code above, changing the parameter of the log instruction ... ldax taptempo ;load tempo in acc log -1,-0.27178149 ; ( logbase2(x) / 16 ) * -1 + ( logbase2(8*pi/ 512)/16 ) exp 1,0 ; 2^(acc*16) WRAX SIN0_RATE,0.00 ... But I didn't test it yet....

Hi Larry

can you share your final code? I'm trying to achieve the same thing, I guess (adapting the infamous tap tempo delay to a sin LFO for a tremolo), and it would be helpful, because my head is spinning with so many number conversions....

Hi,

I'm unsure on how to translate the rate value used in WLDR (integer) to a number I can use with WRAX RMP0_RATE (in decimal)

is the range of RMP0_RATE from -0.5 to 1, corresponding to -16384 to 32767 ?

Don't convert the HEX to BIN. The programmer should be able to load the hex file directly.

in US you can get them from

But I thik there is a shortage due to some manufacturing issues.... you might need to wait for some weeks

I have a similar programmer and can confirm it works for 24LC32A. But getting the right drivers/software was a pain... good luck.

Not sure if this is the case,... but I see you are copying ADCL to DACL or DACR alternatively, but never "reset" the unused dac to 0. This may create some jumps... Maybe it would be a better approach to copy ADCL to both DACs first, .. and then set to 0 the one you don't want to hear. OR s...

If the LED is on all the time that can mean the oscillator has not started or the EEprom is empty or not working.

Is this really working? I had the impression that the ADC is only valid for AC signals.....so a DC only would not be detected.. But I might be wrong. Mat My fault.... I didn't realize he was feeding the ADC with a square wave... I thought it was just a high or low state. So, igorp, what you propose...

Wow, this one is really improved and very usable.
I love it

Thanks Igor!

- How the repeats are created ? I honestly think this block is wrong.... feedback control is not doing anything. I use the "Coarse Delay" instead. - If I want to get a 1000 ms delay can I just replace the lines 5 and 6 by SOF 0.0,1.0 ? What the point of having 2 lines here since we could ...

Ok cool. It works now but here is the weird thing. I have two of the same unit that both work with some other stock reverb code. But when I flash the 24LC32A with this code, it works in one but does not work in the other. Again, a different reverb code worked in both. But with this octave code, onl...

You might be able to do it with less code, I don't think lowpass filtering will help though the pot inputs are already lowpass filtered. You could try reading the pot input and if it's below some threshold flip the "latch" value, then have a counter to create delay before you check the sw...
