SYNTHI-JS - Free Online EMS SYNTHI

This is pretty cool.

You can play with it here. Try loading some of the different patches. I noticed I had to turn up the volume a bit to hear the first two patches. Be careful of course. I'm not sure if any of the patches get considerably louder.

You can find the source code on github here.

Details captured for the archives:

"SYNTHI-JS is an emulator of the legendary EMS Synthi A modular synthesizer, built in JavaScript on top of the Flocking library.

Getting Started

First, open up SYNTHI-JS and take a look around.

SYNTHI-JS can look daunting at first, but creating patches with it is actually quite straightforward. The patchboard functions as a routing mechanism: device outputs on the left side of the patchboard get routed to device inputs on the top side of the patchboard.

Let's make our first patch! Click on the button at B1 at the patchboard to connect the sine-wave output of Oscillator 1 to Output Channel 1. You should hear a 440 Hz sine wave coming out of your left speaker – congratulations!

"Roland RS-505 that is in perfect technical condition (see pics). A few weeks ago the RS-505 was completely checked by an experienced technician.

Looking at the pics you undoubtedly notice that this RS-505 has got a custom paint job that was done by a previous owner. Some might say that the choice of the used colours is kind of "crazy" others might find it a "piece of art". The print job itself is certainly not perfect (means collector´s item) but really well done."

Syntronik & Yamaha DX7 - Sound Comparison Minimoog, OB-Xa, CS-80, Jupiter-8, JX-8P To SY99 & DX7

Power DX7
Published on Aug 7, 2017

"Syntronik is a sampled waveform based VST that emulates legendary synths such as Minimoog, Oberheim OB-Xa, Yamaha CS-80, Roland Jupiter-8, Roland JX-8P and Yamaha SY99.

As I can never afford (nor I have space to keep) all of those legendary synths, I bought Syntronik so that I get to play and learn more about those legendary synths.

As I’ve been making analog/subtractive synth-like patches on my DX7, I decided to put my DX7 MK1 against Syntronik with mighty legendary synths like Minimoog, OB-Xa, CS-80, Jupiter-8, JX-8P and SY99.

In this demo and comparison video, you will watch and hear sounds of the DX7 MK1 compared side by side to Syntronik legendary synths. Some sounds are close and others are different in many ways.

Although the DX7 can’t do everything that analog synths with a resonant filter can do, the DX7 can stand its own with unique sounds that analog synths may find very difficult to emulate.

I will take you thorough from very easy installation and set-up steps. I will give you a quick tour of Syntronik interface and legendary synths.

Comparison
Yamaha CS-80 with a synth brass for UK Alaska Vs Power DX7 signature patch, Alaska with a natural flanging effect

Yamaha SY99 with bell and electoric piano Vs Power DX7 signature patches, Bell X2 and E.Piano (beefed up version)

Minimoog with Resonant stab bass & Resonant Sequencing Vs Power DX7 signature patches, Resonant Stab Bass and Resonant Sequencing. As the DX7 doesn’t have a resonant filter, it needs to generate all harmonics using its FM synthesis. This produces a resonant filter-like, yet very distinctive tone with a ‘Sticky’ feel.

Roland Jupiter-8 with Resonant Unison Lead (16 Oscillators stack) vs Power DX7 signature Resonant Lead with ear piecing mid range (no unison for the DX7)!

Roland JX-8P/ JX-10 with Saw Pad Vs Power DX7 Signature Saw Pad
Oberheim OB-Xa with Rush Subdivisions and Van Halen Jump Synth Brasses Vs Power DX7 Signature Rush Subdivisions and Van Halen Jump Synth Brasses

Oberheim OB-Xa with a warm pad Vs Power DX7, Earth 1, the mother of all pads!

To finish this demo, I include a brand new DX7 song called ‘Resonance Beat’ by combining various Power DX7 signature patches, including Bell X2, Resonant Stab Bass, Resonant Sequencing, Earth 1 Pad. Also it includes a new Bell (like a small bell rolling around inside of a glass bottle), a Resonant Filter Sweep sounds and another Resonant Sequencing sound with a formant type tone when played soft (yes, you can have two different tones in a single patch for the DX7!).

Enjoy!"

"Square wave LFO (filter) comes from the MS20.

You use the CV control input on the back. You can also plug a footpedal in there, I have even tried it with audio once and it worked (only very low frequencies and you need a soundcard that doesn't block DC offset). Be careful."
