Multihead Tape/Drum Echo Proof of Concept using Daisy Seed & PlugData

[@flywittzbeats4008]

This project is absolutely brilliant and I hope you’re proud! I had the hardest time trying to get pure data or plug data to work with the seed. So much so that I just went with a raspberry pi. I am jealous of your mathematical understanding and am wondering if you have suggestions for understanding more math and trig functions in pure data. Thank you so much and congrats again on this awesome project!

Thanks, I got side tracked and a bit discouraged by the 1khz noise from the Daisy processor. I thought I could mitigate it with some of the analog noise filtering suggestions from various forums, but it was was always there so gave up for some months. When I psyche myself back up to get back on this project I plan on trying the overclocking solutions combined with the analog ideas that seemed to have worked for others. As far as the math, the only math I did was the transfer functions to scale the gain/saturation versus the feedback and output. And that was mostly cheating with ChatGPT. (that saturation control here for example: kzbin.info/www/bejne/lWnSdKKZe52pm80) Once I got the Daisy Seed to be recognized by my computer properly (using the Zadig USB driver tool), it seemed like Plug Data behaved pretty well. The only issue I had was I had to compile for size not speed since my program was taking up too much space in that memory. My apologies, I've forgotten which type of memory onboard the Seed is the larger but PlugData will put it there if you compile for size. I had to do it that way since you are limited to 999 or 1000ms of delay using the RAM, if I remember correctly. Eager to hear any synths or effects done with the Pi!

@@MondoJim oh man, I’m so sorry to hear that. I know exactly how that is. I lost interest after trying with the Daisy for two weeks with any free time I had and didn’t sleep very much haha. I don’t hear the noise you’re referring to honestly in the video. To me this sounds like a beautifully made tape delay, but I don’t doubt it’s there. I think what electrosmith and the Daisy is trying to do is awesome, and will continue to support it how I can, but it certainly doesn’t come without its issues. I did get a little FM synth made for about ten mins until I tried booting another patch. I think it was mostly hardware issues on my end because my computer is old and runs it’s os with legacy patcher. But none the less, even when I would get the patches to boot I would run into issues. Hopefully I can get them to work though because I bought 3 of them haha. As far as the noise, from what I’ve heard the audio chip in the Daisy is really good, I didn’t get it working long enough and out anything close to intensive on it to hear what you’re talking about. But I would then be curious about a sample by sample mitigation algorithm. Only problem is I would guess that would have to be done with the fexpr object which I don’t think is supported by heavy. Not sure if you have tried Gen~ for max for live, butI have been trying to learn some when I can and read the book Graham Wakefield wrote called generating sound and organizing time. It’s really good and I have yet to set up Gen with Oopsy but apparently it runs well on Daisy. From what I have read I gotta say it’s an amazing program with awesome sample by sample algorithm possibilities. I am very new to all this stuff and am just trying to practice pure data patching for now, I also just ordered a raspisound with in and out dac for my pi and I will certain let you know what I think. Really excited to hear how this tape/drum echo develops! Cheeers man

@@flywittzbeats4008 "Heavy" or hvcc supports setting blocksize and samplerate now. So I might be able to use the same technique that Sonic Explorer used but, hopefully, with less C++. kzbin.info/www/bejne/a5PYpHp_nKqNnJo He did something with those settings to raise the frequency of the noise up high enough that it was easily filtered out. But I believe he coded his pedal without visual editors like PlugData, etc. A little too hardcore for me. :D I considered Max/Gen~ but PlugData's ability to compile and load directly into the Seed made it too handy go elsewhere. I think I can put all of the features into the program that I want with Pure Data so perhaps with a bit of tinkering I can finish the software part and get back to the hardware. I've only designed a couple of PCB's, one boost, one fuzz so this will be my most complex attempt! An easily installable ADC/DAC for the Raspberry Pi sounds like big fun. It seems like you could do a lot with that. I'll be sure to subscribe so I don't miss anything there!

Wow!! That’s so cool that hvcc supports that now. Man I really need to get back on the seed and try it out again. It drove me crazy trying to figure out why my patches weren’t flashing. I was on the discord with the creator of Wasted Audio who took over heavy after Enzien haha. I showed him pics of my patch and I was certain I set everything up properly and even he was confused as to why it wasn’t working lol. But oh well, it is nice to know it really is supposed to work at least. Ah so you have windows. Yeah I have an old windows 10 Samsung laptop and maybe I will try flashing some patches with that! It seems like people are having a lot of luck with Zadig. Also thank you for the math tip! I don’t know why I didn’t think of using ChatGPT. I used that with a midi controller prototype a few months ago and haven’t used it since. It’s funny how you mention you used the functions for scaling because that’s exactly what I am having such a hard time with. I will certainly give that a go. I would love to send you my synth I’m working on if you’d want to check it out. It’s a wavetable/additive work in progress synth with some simple fm and and clipping capability. I’ve just gotten it to run on the pi and honestly… I’m amazed. Even with the onboard pwm dac on the pi 3b surpasses my expectations. Now, mind you, I am a Lofi fiend so my taste is certainly unconventional. I will be happy to either let you know how the dac I am getting sounds, or maybe even make a video of my own (: Also I haven’t heard many multihead tape delays so I think I will dive in soon and hopefully provide you with some more useful thoughts on the subject. I am also extremely excited to see what you do with yours!
