    Alternate Online FV-1 Dis-Assembler

    I have no idea how he does a Shepard flanger, but were I to attempt such a thing I'd start with: 2 servo flangers with synchronized LFOs. This might be a bit tough because the LFO probably wants to be a ramp to go linearly from 0 to 1 (or vice versa) and then snap back to the other end. And...

    Starting to use ChatGPT to write optimizer for SpinCAD

    This falls into the "may-never-finish-it-but-who-knows" category. I was working on something for work and complaining about the need for a small utility that would take me half a day to try to write because I don't do that sort of thing all the time. My boss says "see if you can get ChatGPT to...

    SpinAsm IDE issue with decimal numbers

    Let's just say that the Spin IDE was last updated several major versions of Windows ago. I did chat once with the guy who wrote it.

    Grain delay

    One method for "cheap" granular delays which aren't really is just to have some fixed delay taps and then use a multichannel mixer to fade them up and down so are you are getting changing overlapping delays, simply because it's changing from one tap to the other. Try a 4-tap delay into a quad...

    Anyone ever use the T/X block in SpinCAD?

    Well, that's interesting and it just shows to go you. Upon further analysis half of what I thought it was doing is not even there. It is like massive crossover distortion with smooth clipping on the top. If your signal is hot enough it seems okay. Well, save that version of SpinCAD along...

    New SpinCAD HEX file looks different. "invalid digit "8" in octal constant"

    For reference, I don't think I've ever changed anything about "Generate Hex". It was part of the functionality I inherited from Andrew Kilpatrick. Also, don't worry about asking questions which you subsequently figure out. This is one of the best ways to debug things. If there is no risk of...

    Anyone ever use the T/X block in SpinCAD?

    OK, this is somewhat embarrassing, although it doesn't sound like anyone else figured it out either. The "Distortion" program in the free programs area is actually based on this "T over X" concept. This is discussed/implemented in 3 different places on the Spin website with no explicit links...

    Anyone ever use the T/X block in SpinCAD?

    I spent a bit more time looking at this last week, and improved the T/X block to behave the way it is described in the Spin Knowledge base (i.e. not filtering the final stage). I also added more detail to the "Wave Shaper" block descriptions at Gitbook (the help pages). Started trying to...

    Anyone ever use the T/X block in SpinCAD?

    OK my curiosity got the best of me here. I went back to the original Spin Knowledge Base articles about the "T Over X" distortion (linked above in previous post). I took the SpinCAD block back to just one of these (as implemented, it was 4 in a row). I auditioned it in SpinCAD Designer and it...

    Anyone ever use the T/X block in SpinCAD?

    What you've done there is to replicate the MO of the crossfade 1 block. It has a 6 dB dip in the middle assuming you put the same signal in both sides. Crossfade 2 has a 6 dB bump in the middle. Crossfade 3, which I finally got working earlier this year, gets to 0 dB at the middle and ends...

    Anyone ever use the T/X block in SpinCAD?

    The 3 dynamics blocks (they are described as limiters) in SpinCAD were taken straight out of Spin's free programs and don't represent a deep understanding of the subject on my part. There's actually a fairly decent section in the Spin Knowledge Base about making an adjustable dynamics...

    Anyone ever use the T/X block in SpinCAD?

    LOL thanks CC, I think I am just going to try to fix the T/X block in place. As far as a "sustain" block, maybe there's a compressor with a control (or controls) at mstratman's Github repo, perhaps one of these days I can see about adding that, as long as I do not have to think too hard...

    Anyone ever use the T/X block in SpinCAD?

    The T/X block was supposedly based on this Spin Knowledge Base article which shows how to get a smooth overdrive. http://spinsemi.com/knowledge_base/pgm_quick.html#Distortion I've never really used it myself as I never thought distortion was the FV-1's strong suit. The other day I decided I'd...

    New SpinCAD Designer Release 0.98-1042 removes register limits

    https://github.com/HolyCityAudio/SpinCAD-Designer/releases/tag/0.98-1042 I have been talking to some people working on a programmable Eurorack module. They have developed a way to convert Spin ASM to C that can be compiled to run on this module. Since they are converting to C they do not have...

    Looking for .spn files for use in Disting NT

    I looked at the ES Disting NT yesterday, wasn't clear but I guess it's simulating an FV-1 on some other CPU. You can make larger patches with SpinCAD than will fit into the FV-1 already, though I don't remember by how much. I'm not much into opening up SpinCAD again personally but if someone...

    Any of the filter pedals feature 24 dB/octave?

    Yesterday I was visiting a friend who is a professional guitarist. He has been dabbling in modular synthesis lately and was saying that he wanted a filter on his pedalboard more like the Erica Synths filters , e.g...

    Filtering with FV-1

    You might also try the 1-band EQ for the notches. You'll have to determine the notch depth experimentally from the "level" parameter. Regarding bandpassing from 100 to 5 kHz I'd just implement those as separate highpass/lowpass filters.

    New SpinCAD release pending - I ain't too proud to beg.

    Thanks a bunch @Paul.Ruby :love: and anyone else who contributed! I know nothing about the Spatialist reverb. Generally speaking it's "possible" to combine SpinCAD generated code with ASM from some other source BUT there are also pitfalls that would be hard to manage unless you're familiar with...

    FV-1 DEV BOARD ...Now what? (noob woes)

    Do you have a way to select the internal programs? Sorry I am not familiar with the board. If you can run an internal program that would point to something being wrong with your EEPROM or circuit in that area. Also, try a bypass program in the EEPROM, e.g. RDAX ADCL,1 WRAX DACL, 0 RDAX...
