    Here I am in 2021, scratching my head trying to figure out how to buffer samples in JUCE while the guys in the 70's were writing DSP algorithms in assembly... truly mind boggling.

    Can you elaborate on why there’s a gap between now and only like 50 years ago. I’m thinking of pursuing a career in DSP and I’m just chilling watching these videos and I’m like man tf is going on with this “Archaeology” topic. I’d love to know more

More creatives than ever can make music and the role has switched from the artist making their own tools to the tools being made available for purchase by audio engineers. That's why there's such a large gap.

    This was amazing and so much better than the "like and subscribe" kids with their GoPro and intro graphics. It really helped me understand where reverb came from and the meaning behind the parameters that we can adjust in a DAW/plugin. Admittedly, I don't have the background to make it past the first 35 minutes but I'm sure it was just as fabulous for those of you who do. THanks a ton for this.

    Fantastic! I've watched this 3 or 4 times now. Massive respect for Sean and Valhalla. I tried to look up the Seattle Music Machine Salon to see if this was a one-off event or temporarily paused with the shutdowns, but found the website is offline. Does anybody know if this will resume? I recently moved back to Vancouver (CA, now WA) and would happily make the trip down for the next one now that borders are open again.

    I stopped doing SMMS when the pandemic came around. Sadly, I find myself too busy to think about organizing it again for the time being. As far as synthy things in Seattle to come down for, the Velocity fest Aug 27-28 will be a great event! There are a few other videos online from SMMS talks on this channel.

    Great talk! (Still going over the whole video so I apologize if some of this is addressed in the video further along) 36:30 - Jon Dattorro designed the algorithms for Ensoniq's ESP effects chips, prior to 1994 (the EPS 16+ and ASR-10 came out well before 1994, approx. 1990-1992) so it's interesting that Lexicon tried to prevent him from publishing his work, as he'd already probably done most of it already for Ensoniq (eventually bought by Creative Labs, who killed all of the IP in preference to their previous E-mu acquisitions, so sad)... I actually mailed Mr. Dattorro earlier in 2019 asking if he'd consider a modern re-release and he didn't rule it out, but was leaning towards a VSTi type release in partnership with someone who could do the actual implementation (hint, hint....). Personally I'd prefer a 'hardware' unit with plugs please :) Would you ever consider re-modelling the ESP (?) algorithms designed by Jon Dattorro (esp. the huge 'hall' reverbs) from the Ensoniq ASR-10, DP/4 etc? I have never heard another reverb that's capable of sustaining a sound for 2+ minutes(!). I have no personal experience with the Lexicon, but Ensoniq's EFX actually beats the Lexicon 224's '70 seconds' by a wide margin. I'd have to dig out my DP/4, but I do believe some parameters go to '120 seconds' and used it in some ambient tracks for exactly that reason. There are resources online incl. old diagrams and dev docs on the algorithms the ESP used, and the Ensoniq docs for those units show block diagrams that are probably useful to an effects designer such as yourself (and Mr. Dattorro filed patents, which now are likely expired and could be used for research) so hopefully it could be re-implemented in modern hardware or software. I regret selling my ASR-10 and would absolutely *love* a small modern box that could do those same reverbs.
