Spin Semiconductor

We have been made aware of at least one fake distributor in China. The ONLY legit distributors of FV-1 and related dev boards are Experimental Noize, Profusion and Microtips. Any other company is not an authorized distributor and should be avoided at all costs.

Please do not repost the same question, I answered that in your first post on this.

Due to the way the pitch shifter works there will always be a delay. We need to save some sample before we can pitch shift them.

OK, something odd with the assembler. On a short test program it will catch "jmp" as an error but on a longer program it may not flag it (or it drops the error, not sure at this time). In any case don't use "jmp", what to replace it with will depend on the surrounding code and wh...

This is strange, on my personal machine I am getting the same thing as you and no error. Need to dig into this a bit.

Finally got a chance to try it and SpinAsm is giving an error for unrecognized op code:
<0000>[ Pass 2] [ 1030] Line: 2 "jmp lbl1 " - ERROR:Unrecognized or obsolete opcode - jmp
Can you post the code that appears to assemble?

You are correct that there is no JMP instruction so I would expect that SpinASM should throw an error. I will try to test it this week and see if I can determine why it is assembling to the code you show.

You could wait to change the pointer until after the user stops moving it then jump to the new point but you will hear a discontinuity in the sound and the user will feel a delay in changes. So comes down to do you want to hear pitch shifting or glitches?

Open source, USB C interface for in circuit programming of EEPROM, browser based assembler/eeprom programming so works on Windows, Mac, Linux, etc. use Chrome for best experience https://sandboxpedal.com/

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 y...

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 mov...

SpinCAD questions should go to a site like PedalPCB as DigitalLarry is rarely here so he may never see it.

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.

What you get out of the "CHO SOF" instruction depends on which LFO you selected and the settings of the bits in the C field. But there is an error in your command and I see it is in the SpinAsm PDF as well, the proper format is: CHO SOF N, C, D not CHO SOF ,N, C, D this is in the example y...
