What a nice comment! Thank you so much! Glad you are enjoying the vids

Thanks! Would love to do more tutorials. My problem is I don’t often know where I’m going with an idea, then by the time I have figured it out, it’s finished. I might do one for this patch though as it is a very useful technique

It’s basically Karplus-Strong synthesis. I’ve implemented different audio processing for +ve and -ve signal values in the feedback loop, which creates non-linearity and resonances. The stuff from the book is only a resonant biquad filter, it’s used in the feedback loop of the Karplus Strong chain to shape the response and provide the tonal characteristics of the model. I don’t know if this is very scientific though - I am not an expert! I like how it sounds though ◡̈

You could try using a simple mix/history filter instead of the GO object, it won’t be exactly the same but it will help you to get to grips with how filtering the K-S feedback chain can affect the sound

@@ersatz_ben Thank you so much for the explanation! I finally got a chance to play around with this. Running the builtin svf~ filters into a delay with feedback seems to work about the same! This is the best drum synthesizing I've found

To show the range of sounds you can get from a simple physical model - and to provide the source code so others can play with it

Yeah the OG music is here, I later added some params and custom JSON to get it to work with Daisy pastebin.com/NUKMWHb7

@@ersatz_ben Oh yeah, familiar with the Daisy integration process. That's sweet! Thanks mate, can't wait to get mine shipped

I really don’t like doing that, cos the cords can become much harder to trace, making the patch much harder to debug in my experience!

What do you mean lol it is already pretty well organized already

@@zoljol I guess you're right! Maybe I work more neatly than I thought. I tend to straighten up the longer patch cords that run from one side of the patch to the other, if they are getting in the way of other objects

Thanks! I can’t share the whole thing but will share some of the key bits soon

Ah sorry! Fixed!

Thanks! An event is something like a message or a bang that is passed between objects in Max. Events are very commonly used for controlling things in the patch. This is like normal computer code where events are scheduled and processed sequentially. A signal is audio information like sound or a CV/gate signal in eurorack world. Signals are processed by MSP objects (the ones that end in a tilde~). Audio signals must always be processed with super accurate timing otherwise they sound wrong, but you can exploit that aspect of a signal to achieve incredible timing accuracy for other purposes, eg for accurate triggering of notes (as in this patch). This is the world of DSP and it is very powerful. Hope that helps

@@ersatz_ben that sounds so interesting thanks for the knowledge .

Thanks v much! There’s a really good book called Generating Sound and Organizing Time by Wakefield and Taylor - it is basically a dedicated gen~ cookbook and covers lots of the core concepts for working in gen~. I highly recommend it. The trick with the accum operator was my way of trying to emulate the count~ object in Max, which can be used to very precisely measure elapsed time. (Accum is covered in chapter 2 of the book!)

I will upload a schematic soon and might do a build video for the hardware which is quite flexible for multiple applications so will be useful to share!

@@ersatz_ben bravo!!

Yeah that’s exactly it, and you can connect the + of a 9V DC supply straight to the VIN pin to power it. You do have to make a custom json file for the ADC inputs (and then browse for that in the oopsy bpatcher) but that’s all easy enough. The hardest bit for me was learning to solder! Also you have to provide 3.3V to the pots/switches separately if you have more than 6 or so, but that is also quite easy to achieve with a cheap voltage regulator.

@@ersatz_ben oh wow! just going straight from 9V that's awesome. I gotta dig up the seed ive got stashed around somewhere and start working on something similar. would absolutely love to have a stereo efx box to throw all sorts of weird patches onto

@@f.botello when I get a second I will draw out a schematic! It’s got a lot of potential for bringing weird effects patches into the physical world

It’s just a prototype at the moment but if there is a bit of interest I’ll do a short run!

this is the presentation mode, you can add whatever objects you like and switch between presentation and edit mode in the bottom left on the chart symbol
