Simmons SDS7 Digital Analog Drum System (1983) / hybrid analog drum synthesizer & 8 bit PCM rompler

video upload by ohm_studi_ohm

"in the first part of the video I run a simple pattern on a Roland TR8s that triggers the SDS7, and I demo a few kits I programmed.

On the second part I play live drums over a simple kick / hat / clap pattern and review the same drum kits and finally I play the sounds alone.

I'm no drummer so forgive my playing. These last parts are mainly intended as to demo how the SDS7 handles dynamics.

recorded through a Tapco 4400A reverb. No other fx or editing.

The Simmons SDS7 combines analog drum synthetis and 8 bits sample playing.
Each voice lets you blend 1x VCO (CEM3340), 1x 8 bit sample on eprom (like many 80s drum machines ie LinnDrum, Oberheim DMX, Sequential Circuits DrumTraks etc), 1x noise generator and 1x click generator.
Then those 4 sources pass through a nice 24db resonant filter (CEM3372), which doubles as VCA. There is a simple cutoff enveloppe and vca release parameter, and both the VCO and sample have a simple pitch enveloppe as long as a lfo to pitch modulation depth. The lfo speed can go to audio range thus enabling FM tone, great for bells and fx.
All voices card pcbs are the same except for the eprom containing the sample and this can be replaced with other sound (the clap on this unit is a CR8000 clap i programmed for instance).
There is however a second type of card, hi hats card, that differs from the basic one with some more components that let the voice be controlled by the hi hat pedal (decay of the sound mainly). It's easy to modify a regular card to a hi hat card, and to build a simple adapter in order to use a momentary switch pedal to act as the hi hat pedal. You can even use a progressive pedal to mimic the opening of the pedal, this is what I'm using and doing on the video (off screen). Info on how to achieve this are available on this site (thanks to the author for sharing this ): https://www.drummachines.de/beatboxer... If you're interested in these units tons of info are available on that site (again thanks to the author for the great job): https://snw.lonningdal.no/sds7.php"

April 30th 2025 Patch Variation #2

video upload by John L Rice

"Just exploring the patch as one tends to do. Here I’m using a second Moon Modular 569 sequencer to control the first one instead of the sequential switch I used in the previous video [posted here]. The result was simpler but still interesting to me. I also changed up the synth voice a bit, using a MegaOhm LPG instead of the SSL tube VCA and processing its output with an Oakley/Krisp1 Flanger."

dreadbox Artemis Demo (No Talking) with Presets for Ambient, Electronica and Techno

video upload by Limbic Bits

"dreadbox Artemis – My 2 Cents
Artemis is a polyphonic analog synthesizer with six voices and a comprehensive effects section developed by Sinevibes. Housed in a solid desktop chassis, all potentiometers, faders, and buttons feel great, with just the right amount of resistance. On the rear, you'll find a stereo output, a separate headphone output, plus USB and MIDI connections. It doesn't offer a foot pedal input, but it supports MPE (I still need to try that with my Osmose).

Now to the most important part — the sound. It features that great vintage tone I love so much on other dreadbox devices, largely thanks to its creamy-sounding filters. Both filters offer resonance, and the low-pass filter can be switched between 12dB and 24dB slopes.

But it doesn't stop there: thanks to TZFM and filter FM (yes, noise can be a source here too), it can sound very modern as well, making it great for all sorts of electronic music. Although it offers quite a lot of modulation options, I still found myself wishing for features like key tracking for LFO rate, negative envelope amounts, noise as a modulation source in the menu, or meta-modulations. After reaching out to dreadbox about these features, they told me they are already working on them for a future update and/or will look into them. Based on my past experiences with dreadbox, I’m confident we can expect a nice firmware update for Artemis in the future.

The effects section by Sinevibes is also great — it’s just a shame that there are no external inputs like on the Typhon, as those would have made it a fantastic standalone effects unit as well. You get four effect slots (Lo-Fi/overdrive/shaper, modulation, delay, and reverb), each with several options to further tweak the sound. Here, I would love to see a bit more flexible routing, allowing changes to the effect order. But even without that, the effects section is a great addition that melts perfectly into the internal analog sound engine. I'd only recommend not adding too much, as the effects can quickly become dominant.

TL;DR: dreadbox Artemis is a sweet-spot synth that can also show its teeth when desired. Its intuitive interface and great-sounding effects unit make it an excellent companion for live performances. Definitely a highlight!"

FM Synthesis - A Practical Guide - Part 1

video upload by ChrisLody

"Here's something I've been meaning to get round to starting for ages, a practical guide to FM synthesis. In my experience FM tutorials usually over explain all the wrong things and rarely get as far as the important things like the predictable way operator ratios change the waveform and frequency responses. So I've tried to approach things from an entirely practical view point showing you how to make saw, square, noise etc with filter like responses.

Here's chipsynth MD (from which I stole a diagram :) https://www.plogue.com/products/chips...

"AS500-SEQ connected to a vintage ARP Odyssey.
It’s sending gate and CV to the Odyssey and clock to the Arturia DrumBrute. Tempo and start/stop are controlled directly from the sequencer.

X, Y, and Jump switches are triggered live to modify the sequence. CV is also patched into the Odyssey’s Pedal input for subtle shifts.

Glide from the AS500-SEQ is active throughout.
The DrumBrute’s audio is fed into the Odyssey’s External Input."

Ample Synthesizer: Sweeping Cutoff with Built-In Echo
video upload by rezfilter

"This patch on the Ample Synthesizer features a multi-oscillator sequence running via its onboard sequencer. The resonance is set high to highlight the harmonic character of the filter as I sweep the cutoff frequency. You’ll hear how the onboard echo effect adds depth and movement to the sound. I’m also using the touchpads, each preset to a different cutoff value via its dedicated pot, allowing for quick and expressive tonal changes throughout the sequence."

"Amazing reissue of a rare classic. I bought it a few months ago, somewhat on impulse, and it hasn't found its way into my setup. It is in immaculate, like-new condition without a single blemish and everything works as new. I'm very particular about my gear and always handle it carefully and take good care of it. The unit has always been stored, covered when not in use, in a smoke/pet free climate controlled studio.

This thing is built like a tank (very solid and heavy), has great connectivity options and, most importantly, sounds incredible!"

Echolocator delay on synth, drums, voice and shortwave (no talking)

video upload by Richard DeHove

"First up Erica Synths sent me the Echolocator. That's particularly good of them because I know and I'm sure they know that I would have bought it anyway. After all, I'm the man who bought the Zen delay three times. For delay pedals in general I'm up to about 25 delays bought in the past few years and about 22 sold :D

Here I use the Echolocator with the DB-01, Acidbox III, LXR-02, Tecsun PL-660 radio and the US War Department training film number 471 on triodes and tubes.

No presets are used on any of the examples, it's all live twiddling. The idea throughout is to show the range of real time 'playing' with the delay. Just like the Nightverb I haven't used the presets or programmed any myself, it's so fast to dial in the sound you want it seems better to match things exactly to whatever you happen to be playing. The only thing I think is missing (at least I can't see it) is a WYSIWYG mode where the machine instantly reverts to the current knob positions. The only 'second layer' functions you need to remember are BACK+FREEZE to mute the delay, and BACK+TAP TEMPO to sync to an incoming clock.

Despite the length of this video I've only touched on some of the interesting effects. For example adjusting the compressor makes a huge difference to the feedback; whether the filter is in series or in the feedback loop; playing with the freeze function, and modulation with pitch shifting. So more on all that in later videos. If there's anything in particular you think I should cover please let me know.

Finally, if you notice a slight difference in the video color and position between takes it's because I had to change cameras halfway through.

Reverb to Become Privately Held Again

Press release follows:

Two new investors with ties to the music industry—Creator Partners and Servco—have entered an agreement to purchase Reverb from Etsy

Tuesday, April 22—Today, music gear marketplace Reverb announced that two new investors—Creator Partners and Servco—have entered an agreement to purchase Reverb from Etsy. Once the deal closes, Reverb will be a privately-held, independently operated company backed by two investors that share Reverb’s experience in the music industry and focus on supporting musicians.

“Creator Partners and Servco share our passion for the musical instruments industry and a community-first approach, plus a deep desire to strengthen creative industries,” said David Mandelbrot, CEO at Reverb. “The musicians, shops, and brands who use Reverb have always been at the center of all that we do, and these two partners will help us support our music-making community in new and better ways.”

Known for their focus on the digital transformation of creative industries, Creator Partners is an investment company currently investing in music companies including BMI, SoundCloud, Color Studios and Mogul.

“Reverb is the #1 global marketplace for musicians, and a one-of-a-kind platform that has transformed access to quality used gear for creators of all levels” said Kerry Trainor, Creator Partners Founder and former CEO of SoundCloud and Vimeo, “We are thrilled to join the Reverb mission to make the world more musical, and grow the entire industry through seamless secondhand commerce.”

Servco has been involved in the musical instrument industry since 1937, including a long history with Fender—first as a dealer of Fender music gear in the 1950s, then as part of the group that bought the company from CBS in 1985 and now as the majority owner of the company, as well as an active investor in other musical instruments businesses.

“We are thrilled and honored to be a part of Reverb’s continued success,” said Executive Chair of Servco, Mark Fukunaga. “For nearly 90 years, Servco has been deeply involved in musical instruments and music education programs. And we remain committed to being good stewards of leading musical instrument companies, like Reverb, and supporting players everywhere in pursuing their passion to create music.”

When the deal closes in the coming months, Reverb will return to being an independent business. According to Mandelbrot, buyers and sellers won’t notice any disruption as a result of this news, but he does expect the Reverb community to notice positive changes and new innovations in the coming months as the team continues to focus on making Reverb the best place to buy and sell music gear.

“We’ve got a lot of exciting changes in the works. We’re expanding access to music-making software on Reverb and we’re getting ready to pilot a new option for selling that allows musicians to get paid faster, while skipping the listing and shipping process. Our teams are working on improving our search functionality, making it easier to ship, and shortening the time it takes to resolve support issues,” said Mandelbrot. “All and all, there’s a lot for our community to look forward to and I’m very excited about what’s coming as we move forward as an independent company again.”

"The sampler has been completely refurbished. The casing has been painted black. All tact switches have been replaced, the old LCD with a new LED and pad sensors. Additionally, I have installed the Gotek FDD emulator (32GB Sandisk pendrive included), the latest Vimana 3.15B OS, max RAM memory and multivoltage power supply. This means that it does not need step up or step down converters to work! The voltage switches automatically depending on the place in the world. It accepts AC voltage from 65 to 265V. This is probably the only such version in the world. I was going to replace the LCD window, as it has a few scratches, but I'll leave that to the new owner. The glass is available on eBay, and replacement is easy (double-sided tape). Insured shipment."
