This is very cool, well done! I wonder how far we are away from the following: 1. Being able to use a GAN to be able to give a synth an input sound (i.e. a reece sound from a dnb track) and have it generate a patch that matches it. 2. Being able to do 1 but apply it to a whole Ableton project. The interesting thing about Ableton is that they're actually XML files under the covers. Even if you couldn't get close, it w…

I am not an ML expert so not sure of the details on how it works, but I believe Google’s DDSP work is similar to 1: https://magenta.tensorflow.org/ddsp

As I understand it, their system can take an audio input and “learn” how to control the parameters of a synth to reproduce that sound. I had the pleasure of seeing a demo of it from someone who worked on it and thought it was impressive!

Synths have existed for a while which can use “resynthesis” to take a sound and recreate it using additive synthesis (e.g. Hartmann Neuron, Alchemy), but I wouldn’t probably call this AI/ML.

Just unzip it and then cat the contents into aplay!

dQw4w9WgXcQ alert!! :) That is cool. It's even a valid NES cartridge according to `file`. Nice. I needed `aplay -f 16` FWIW. I shall respond with this: https://www.youtube.com/watch?v=iJgNpm8cTE8

Technically you want to increase the sample rate (to around 14.5kHz) rather than change the depth to 16, but yeah it basically works either way.

This is ultimate vaporwave thing.

It needs just two things:

1) some sanity checking on presets (to drop not working sounds) 2) javascript player on the page (there is web port of DEXED[1])

Oh, thanks. And that's hilarious that both work.

First of all, fantastic tool. Second of all, to folks that are trying to figure out how to give this a go: Open up your favorite DAW (try out Reaper[1] if you don't have one yet), download an install the fantastic open source DX7 emulator plugin Dexed VST plugin [2] and have fun. In my opinion, FM synthesis is one of the finest things in life I've ever experienced. I never understood the whole culture around an emoti…

You don't even need a DAW. When I downloaded Dexed as an audio unit for my Mac (thinking “I'll have to try this later; at the moment I don't have enough RAM free to start a DAW”), I was pleasantly surprised that it also came with a stand-alone app. The Dexed wiki says there are such apps for Windows and Linux, too. Then I downloaded a MIDI file and used Audacity to play some of its channels into the synth. Super easy…

I like using SAVIHost when toying around with VSTs in standalone mode (if they do not offer one): https://www.hermannseib.com/english/savihost.htm

Any instructions for Linux? Dexed won't run there.

Look for FM synth VST’s. There are surely loads of them.

Thanks, I ended up loading the cartridge on https://www.webaudiomodules.org/wamsynths/webdx7/, it works great in Firefox (no crackles).

I know what one is. I'm a fan of fm synthesis and dx-model synths and variants. But if I had known it automatically downloaded a patch I wouldn't click. It did this without me clicking anything.

What browser are you using? It requires a click for me on Firefox. From a quick glance at the source I don't see anything that would automatically initiate a download.
