Hi Guy, welcome to the forum The table of the respective binaries for the internal effects you find in the datasheet of the FV-1, and using an external EEPROM you will use the pins S0, S1 and S2 to select the programs of the external EEPROM, remembering that to access an external EEPROM the pin T0 m...

Hi everyone, I also want to record an external eeprom with arduino, but my knowledge is minimal on this subject, looking at the code above where will I put the binary for the arduino to record in eeprom?

I know there is a possibility of changing the frequency of the Arduino, but it seems like it's a complicated job, I'm going to do some tests with an LPF, thanks for the help.

Hi everyone, I'm trying to control the potentiometer inputs of the FV-1 through an arduino, I already managed to do that and it worked, but the arduino pwm works at 490Hz, can I have problems with pwm noise with this frequency?

Hi Guys, I'm trying to create a modulated delay, at first I used an lfo to interpolate the delay value but with that I get a "zip" noise along with the modulation, now I'm trying to catch the delay signal and modulate it, but it does not work as it should: / . can anybody help me? ;------ ...

At this point, when you skip ahead, your ACC is non zero. skp neg,ENDLED In general I have found that usually the code just after any skip target label (e.g. ENDLED) wants to start by clearing ACC unless you are 100% sure it is zero in all paths that lead to that label. This is based on a 30 second...

Hi Guys, I'm working on a Delay with taptempo with pitch shifter, for this I needed to put the led indicator to be triggered by sin0, however I get a lot of noise in the audio output due to sin0, I already tested this system with other delay that does not has pitch shifter and the noise does not exi...

Hi Guys, some of you have already built the code for a LO-Fi delay, I have been researching how to build one and I have not yet found the logic of the operation, can anyone help me?

You define "filter" as 0.8 but then do "RDAX filter" and RDAX expects a register not a decimal value as the first parameter. Hi Frank, I have modified what you said and now I have a high pass filter controlled by the potentiometer, but I want a low pass filter. I changed the &qu...

Input, Filter, and K were all just used for the sake of example. "Input" should be whatever register you are using for the input to the filter, "Filter" is whatever you want to call your lpf, and "K" is whatever you want to call the cutoff frequency coefficient. In ord...

The combination of RDFX and WRAX creates a simple lpf. In order to modulate the cutoff frequency we need to deconstruct RDFX. Looking at the block diagram of RDFX: http://www.spinsemi.com/images/knowledge_base_img/INST_RDFX.jpg and assuming the input of the filter is in ACC, we see that RDFX perfom...

I really can not identify the problem, my knowledge with the language of FV-1 is low, my experience is only with C / C +

No need to apologize for asking a question! You should start by reading though the knowledge base, particularly this section on low pass filters. It explains the behavior of the algorithm and provides the formula for the cutoff frequency. You should also take a look at the instructions and syntax f...
