Sorry, Fulcrum. I can't share the code itself for several reasons: a) Much of the code will be used in a commercial product (though not octave up/down), so I want to keep it proprietary. b) It is very hard to understand, even with comments and help, and even for someone fluent in DSP and on the FV-...

Hi Alex cool code snippets. I don't have an FV1 board in the bench at the moment, so I haven't tested them, but I will as soon as I can. Thanks for the code Hello, Hi, I tried the code and it's great. However, there's a problem; I don't remember which potentiometer it was, maybe Pot1 or Pot0. The i...

Hi,So, in short, what exactly should I do, Frank?

Thank you for reply. It's something like external loop of mixer, as I shown below. So, I mainly want wet signal out of FV-1, mixing dry/wet is done by mixer. Biggest problem is with effects that normally don't make delay, e.g. hp/lp filters, bitcrusher, etc. https://obrazki.elektroda.pl/8892188300_...

Hello, I have a question. I'm currently using the FV-1's built-in effects and I'm experiencing an audio delay in the pitch shifter effect, which many people dislike. How can I fix this? If I load different effects onto the EEPROM chip, will the pitch shifter effect still have the same problem? How c...

Hi frank.Do you have a code that can do -/+1 like this octave in the demo example I sent you?

I think what is causing me confusion is when you say: I just want the note I specify to go up or down to the lower octaves, that's all. What do you mean by "the note I specify"? Any audio you play into the algorithm will be shifted, shifting is not on a note by note basis. For example if ...

Actually, as you said, the A440 note of the dry signal is like going up to A880 or down to A220. I don't want an additional octave signal to be added to the dry signal. I just want the note I specify to go up or down to the lower octaves, that's all.

I am still unclear on what you want. Do you mean you want to play a note and hear the original note and a shifted version of the note together? So if you play A440 you want to hear A440 and A880 (A440 up one octave) as an example? If this is correct then you do want a pitch shifter that you can mix...

I do not use SpinCAD so you will have to ask over on a SpinCAD forum. The native pitch shifter in FV-1 will not shift by 3 octaves so you will have to calculate the coefficients to use from AN-0001 and use 2 in series. I do not understand "I don't want a pitch shift! I just want the note to mo...

Correct, you use SpinAsm to assemble the code and save it to a hex file and use that to program an EEPROM. If you have a Spin FV-1 dev board SpinAsm can write to the EEPROM on it. Hello. How can I create -3/+3 octaves? For example, can you provide an example drawing in Spincad that will cause the n...

Hello frank.
How can I create -3/+3 octaves? For example, can you provide an example drawing in Spincad that will cause the note I specify to move up or down from the lowest pitch to the highest? Note: I don't want a pitch shift! I just want the note to move up or down a few octaves when I turn the

This is a multi program pitch shifter, inspired by commercial pedals. Its got 6 programs, selectable by pot0. the first 4 are dual shifts, that is 3 note harmonies. Crossfade the 2 shifts with pot1, and crossfade effect and dry with pot2. Fifth program is a single manual shift, with +/- 1 octave by...
