    Terrarium Polyphonic Octaves Code & Demo

    Echoing this sentiment, @keyth72 recently ported it over to the bkshepherd project so I got to play with it (I don't have a terrarium) and really am digging it! Wanted to pop in and say it is running on new hardware variants besides the terrarium so it is super appreciated and I also wanted to...

    EXAMPLE Developing a custom pcb for Daisy Seed - Funbox

    Very nice! That is what I was hoping to hear and makes sense! I will definitely be checking it out on my bkshep 125b (and using 48 for audio block size as well) when I get a chance

    EXAMPLE Developing a custom pcb for Daisy Seed - Funbox

    Awesome stuff! Considering your original amp/IR module (mars I think) is what got me started with the daisy (and porting it to the bkshepherd project on a fork of mine before finding a fork of yours doing the same thing :) ), do you have any comments on the quality/experience/results of this...

    Phase inverting at input buffer vs after effect

    To show I am not a monster and finished my build, thanks for the help all! Also got a blend pot with longer legs instead of bending them (since the pot and footswitch are on the same board, this was an oversight originally)

    PCB Track Width

    I prefer to finish it as fast as possible, very late at night if possible, get the order in so that production "starts", then the next day or week review it obsessively and find out I am an idiot and any amount of patience would have prevented a lot of future-me headaches, then wait 30 days for...

    PCB Track Width

    I don't have a ton of experience, but I wanted to limit variables for my first few PCBs and just did 0.6mm for all traces and had no real issues routing or with zones being weird, even without vias. If you are limited on space or have a complex circuit, then the smaller traces for signal will of...

    Phase inverting at input buffer vs after effect

    Well because I won't fix the board until after the holidays, I may as well post some carnage pics to show the tight fit but overall success besides the 3DPT... I also swapped out the jumpers for coupling capacitors after this pic and it seems good, so will use those instead of jumpers on the...

    Phase inverting at input buffer vs after effect

    For my ears, I haven't added the coupling caps, and the noise level on everything is totally acceptable. I may play with adding some later after the other stuff below is resolved. The build came together nicely from high level standpoint, fits EXACTLY, I don't think I will need to do a rev 2 of...

    Phase inverting at input buffer vs after effect

    Yea both effects will be quite gainy so I am not concerned about it, but I really appreciate the insight. I should do more simulating but people here are such a wealth of knowledge too!

    Phase inverting at input buffer vs after effect

    I will make that change if I need a respin for other reasons that I can't rework. Thanks! I didn't put much thought into that portion since I was just referencing 1:1 from the jmk paralyzer.

    Phase inverting at input buffer vs after effect

    There will be at least 1 buffer between the guitar and this pedal, but noted! Should I change R9, R10, R13, R14 to 1M just in case?

    Phase inverting at input buffer vs after effect

    Any recommendations on values? I was going to use a 1uf on the output of the inverting buffer and a 100nf on the input side

    Phase inverting at input buffer vs after effect

    Ok, I will use a 1uf as my jumper then (output side) of the inverting stage since I am not actually populating a DPDT, does that seem ok? What DC are we worried about in the unity gain inverting opamp buffer/phase invert section, the -VB input? I think the input side is fine because the output...

    Phase inverting at input buffer vs after effect

    I dont think I will have any issues without a coupling capacitor, but if I wanted to I could use a cap as my jumper between pins 5/6 of the DPDT :LOL:

    Phase inverting at input buffer vs after effect

    Thanks for the links! Even in my schematics, the 2nd option ended up being simpler to me, especially since I already had the IC (socket) sitting there waiting for it to be used. Glad to have some other answers/reasons though, so thanks! I probably could have added a coupling capacitor to...

    Phase inverting at input buffer vs after effect

    I have 5 boards on the way so we will see! The traces and layout are SUPER sloppy but its all connected and passed design rule checks so YOLO Pretty obvious that I am going to just slap 2 builds I have already done into a 1590xx with this I briefly tested a parallel mixer pedal, and while...

    Phase inverting at input buffer vs after effect

    Yea I think this looks a bit better

    Phase inverting at input buffer vs after effect

    I think I am going to switch IC1 to a TL072 and add an inverting stage at R2-T that gets skipped or not with the DPDT, seems a bit simpler and only adds 2 resistors. I think in my diagram above R13 would cause issues when the DPDT switch is set to not-inverting. I also will have no doubts or...

    Phase inverting at input buffer vs after effect

    I am working on a custom version (for personal use) of a blend for 2 effects based on the https://jmkpcbs.com/product/paralyzer/ that includes the ability to invert the phase of one of the signals, and also incorporates the 3DPT and led all due to space constraints. My question is, is there any...

    Any harmonizer examples?

    I am waiting for Joel to release his new Hz algorithm! Here is my frequency detector class also using BACF from the cycfi q library https://github.com/bkshepherd/DaisySeedProjects/blob/main/Software/GuitarPedal/Util/frequency_detector_q.cpp I had great results adding a...
