ER-99 Online Web-Based Roland TR-909 Emulator by Extralife Instruments

video upload by Extralife

Update: video added above.

"Play the ER-99 free here!

Celebrate electronic music history on 9/09 day with ER-99, a web-based instrument 🎛️ based on a famous Japanese drum machine from the 1980s. It was built to celebrate 9/09 day 2022 🎉!

All of the drums are synthesized using the WebAudio API. The hi-hats, crash, and ride cymbals are produced from sampled audio.

The complete source code is available on Github:"

Original post:

This one is in via Extralife, maker of the Super Sixteen DIY Eurorack Sequencer, featured in additional posts here.

"This year, to celebrate 9/09 day, I've built a free, open-source analog drum synth you can play in your web browser. It's called ER-99, and you can play it here (works best on desktop devices!)

You can program patches and sequences on the web interface and save them as presets using the menu below the sequencer. (I have also added MIDI input for sync with external sequences).

You can also read the complete source code on Github. It's surprising how simple many of these sounds are to make!

The original Japanese drum machine that inspired this project is an analog sound design masterpiece, and you can read circuit analysis about its clever use of noise and bandpass filters over on Network 909. I've tried to use the same techniques in the digital domain but I'm sure I can tweak them to get even closer sounding:"

LOOPZ - Batchas Pointz & Sudden Infant

video upload by batchas

"I developed this web app in 2001 and published different versions until 2009 with loops from various friend artists. Playing audio in good quality on internet and controlling volume in realtime was still quite rare and not yet self-evident. I also made a few standalone versions for PC/MAC. On the last online version I did around 2005 you could load your loops, record your mix and play a mix saved on the server. But it never passed the BETA stage, because a web agency engaged me for a larger project and I was too busy the following years."

Wednesday, December 15, 2021 - Online Elektron Inspired Groovebox with Sample Import

check it out at

Mouse over the controls for tips at the bottom of the player.

Some details via Create Digital Music

"maxjvh writes us to tell us about their creation, a labor of love inspired by Elektron’s fine groove hardware and workflows. It seems ideal for the person who adores their Elektron machine enough that they want to have some echo of it even looking back from their browser.

We’ve seen lots of these kinds of creations over the years – ah, remember the days when some folks were predicting browser tools would replace everything else? But this one is unusually powerful.

You get support for your own samples, for one, and easy secret link sharing of grooves you create means you can use this as a collaboration tool – or just a way of sending folks your feelings by drum machine pattern instead of words.

Single cycle waveforms? Yes. Powerful voice architecture? You bet. Per-step trigger conditions and p-locks and microtiming? I mean, honestly, this actually bests a fair amount of hardware. Add some sends and you could even finish stuff on this – but it also looks like a cute way of making some loops at random times that you can later load on your DAW or hardware."

The full feature list:

sample-based sound generation with support for single-cycle waveforms

almost all parameters can be modulated on a per-step basis

each track has a multimode filter, distortion, frequency shifter, sample-rate reducer, and amp envelope

three freely assignable modulation sources per track (essentially flexible LFOs that can be used in one-shot mode)

steps have micro-timing, retriggering, probability, and trigger conditions

tracks can have individual lengths and sequencer speeds (the latter can even be step-modulated, because why not)

four send effect: chorus, phaser, reverb, delay

a master compressor and soft clipper

macro controls for working with all kinds of inputs (check out the shortcuts)

pattern sharing via secret links (e.g. tahti 13)

RC-808 Re-Create the 808 Official Website Update From the Makers of the Original Roland x0x Series

RC-808 Re-Create has a new home with some updates at Click through for the new site. Note RC-808 Re-Create is from the original developers of the Roland TR-808 & x0x series. See this post for a pic of the "Analog Mafia" as they are known, along with some initial details on the project.

Regarding the new site:

"At the moment we are busy developing the VST / AU plug-in versions on Win / Mac environments. We are a very small entity with very much limited workforce, centered around Tadao Kikumoto, the project leader of the vintage TR-808. The sheer amount of parameters derived from the vast 8 partial architecture makes it a tough challenge to realize automation on DAW. Yet still, we will bring the plug-in edition to you very soon.

Again, because we are interested only in distributing our own vision of what we actually wanted the original 808 to be, and as the token of our deepest gratitude to all of our great beautiful fans of the 808, we are providing this as free of charge, still even now, as it was from the beginning of this endeavor.

The 808 is only the beginning. Create your own sonic universe, and voyage across the gulf of sound space from here.

Thank you so much for your patience.
Stay safe, stay healthy, stay cool, and please please do take good care of yourself."

Novation Circuit Pan Automation


"This video demonstrates pan automation on the Novation Circuit using the Circuit Bender web application available at

My music on Bandcamp:

The Novation Circuit is connected by USB to my laptop running the Chrome web browser. The Circuit Bender web application listens to the incoming MIDI messages from the macro controls for Synth 1 and Synth 2 on the Novation Circuit and sends the MIDI messages for synth and drum panning back to the Circuit.

Since macro controls can be recorded and played back by the Circuit, it is possible to achieve pan automation on the Circuit using the Circuit Bender web application. This web application will only work in the Chrome and the Opera web browser, since they support Web MIDI.

This is a hack with some limitations, but it works for me, and I had a lot of fun creating it. Enjoy! And let me know about your experience with this in the comments :-).

Roland TR8 vs TR-09 vs Cloud - TR909 Comparison

Published on Sep 9, 2019 Starsky Carr

"A quick look to see how the various Roland emulations of its own magnificent 909 compare with each other.

There some speculation about the different technologies and algorithms - this demo is purely looking at IF there are differences between them..

This isn't meant to be a fully fledged demo or review of the drum machines - just looking at if there are sonic differences and if so what are they.. :)

and there are!

Fragment - Abstract ambient JAM - Subtractive / Karplus / PM / Additive / Granular

Published on Apr 14, 2018 Fragment Synthesizer

You can find additional posts featuring examples of Fragment here.

"Fragment is an online collaborative additive / spectral / granular / subtractive / PM synthesizer and live-coding web. platform, the spectrum is created by a live GPU script, the generated visual is then converted to audio by an additive/granular/spectral/subtractive/PM process, Fragment is basically a programmable noise-of-all-kinds software.

This is a video of a live jam session featuring all types of synthesis (in order : subtractive / physical modelling / additive-fm / granular) supported by Fragment and the improved subtractive synthesis algorithm (Poly BLEP) which allow fast and anti-aliased subtractive synthesis, this is still WIP (problems with filter resonance) but quite usable as demonstrated with several acid-like patterns!

Renoise DAW is used in the background to output audio + MIDI out and add reverb / delay (Fragment is also used for delay effects).

4 instances of the sound server are used on an Intel i7 7700, 14Gb of RAM and a gtx 970 GPU.
