In this video, I present a (very long) comparison of three synths from Roland: JUNO-6, JU-06A, and JX-3P. All three of these use the same legendary IR3109 analog VCF chip. In the case of the JU-06A (JUNO-60 digital recreation) this VCF chip is modeled with Roland's ACB tech. My JX-3P has about a 30% resonance boost, which brings it closer to JUNO territory. A JX-3P from the factory has very mellow resonance that doesn't really even squelch. Anyone with a JX-3P can perform this "mod" as no special skills are required (see link below to my vid where I did this).

This video will probably benefit me more than anyone else, but who knows? Some may find it interesting or useful. The goal here is to compare and discover differences and similarities between these synths when it comes to key sonic traits, such as: the sound of the filter at high resonance, filter key follow behavior, envelopes, VCA (in gate mode and envelope mode), Chorus, and Pulse Width. If that sounds boring, feel free to move along to a channel that does more lively comparisons. There are plenty of good options out there! I may do a patch comparison at some point down the road.

There is no talking in this video. I don't want to sway anyone's opinion with my commentary. Rather, it is just a simple presentation with visuals and on-screen text to indicate what's going on. I did my best to match the settings for each sound. Feel free to let me know in the comments if I screwed something up.

Lastly, any additional noise and hiss beyond the innate noise of the chorus circuit is totally my fault. I had 2 other inputs cranked on my mixer unnecessarily.

Nicholas Semrad's Sequential Rev 2 "2nd Edition" Patch Set (Demo)

video by Nicholas Semrad

"Here is a demo video for my now available-for-purchase Sequential Prophet Rev 2 "2nd Edition" Patch Set. You can purchase these patches at my website, If you've already purchased the first set, send me an email at "" with the subject line "Proof of Purchase" and a screenshot of your receipt and I'll send you a coupon code for $10 off for this set!

I've made another 50 patches (10 basses, 10 leads, 10 pads, and 20 aux key patches) for this set and it includes many patches I've recorded with and played live. For this set, I've really taken advantage of the stereo spread and some advanced modulation techniques to capture a bit more of the old-school instability of the original Prophet synths while still mixing it with many new sounds.

Thanks again to Emily Hoerdemann for the cover design!"

"The embedded youtube video is of the unit for sale here at reverb, with audio fed directly into the camera. The unit is in good condition, but operationally, the keybed has some issues, with some notes not triggering.The bushings on the keybad feel good, but a keyboard tech is needed to bring the unit up to 100%. It is, as demonstrated in the video, perfectly playable over MIDI."

Additional SYNTH CITY Listings

"The Xpander is a six-voice desktop version of the Matrix 12 with which it shares an identical voice architecture. In many ways they are the most flexible non-modular analog synths ever built. Each voice has five LFOs, each with about five different wave shapes, plus the ability to sample most other modulators.

This Xpander features the very rare Oddernmart Xpansion mod (professionally installed) which allows 6 audio inputs to be introduced to the signal as the VCO-2 Noise component. All functions have been tested in great working order, AC power cable included.

Recently serviced by our in-house technician:

"The 106S is identical to the Juno 106, but with the addition of two built-in speakers. If you wish to disable the speakers and only utilize the outputs, you just need to insert a 1/4" jack into the "phones" port. The model's counterpart outside of Japan would be the HS-60."

Shifting Shapes | Intellijel Shapeshifter Exploration

video by Cinematic Laboratory

"Here's a second session with the ShapeShifter, an amazing complex oscillator with digital waveforms and an analog wavefolder. In this video I wanted to explore some 'normal' sounds but it's hard to resist the sonic power of two high resolution wavetable oscillators and an arsenal of features to combine, sum, fold, shape, morph and mangle them. It's probably one of the most complex oscillators on the market."

"Still getting to know the Wasp again after all these years (and through something better than a cheap guitar practice amp ;-) ). I so need to sort out my workspace and up my production values a bit but stupidly busy as ever and prefer to spend my music time playing rather than sorting things out right now :-)

Vintage Synth Lab demo Eurorack modular analog synth VCO-81 VCF-74 D-ENV

video by Vintage Synthlab

"Analog modular eurorack synthesizer demonstrating the fast envelope action of the D-ENV (Delayed Envelope Generator), with the VCF-74 Mk2 (analog diode-ring filter module based on the 1970s mini-Korg 700 700s), and our VCO-81 (CEM3340 precision, high-quality analog VCO - unreleased). Our N-STH (Noise + Sample/Track & Hold) is used to provide white noise for extra snare sound, S&H routed to the HP filter of the VCF-74, and Track & Hold from another N-STH is used to slew the pitch of the CV controlling the VCO-81 (pitch) 1v/octave.

The result is a warm, analog, singing mono-synth voice, full of endless possibilities of character to dial in whether live, recording, or used as a tool for deep sound design in the pro and commercial audio industries."

Using CV to create generative ambient with the DB-01

video by Richard DeHove

"The Erica Synths DB-01 plus a single Eurorack LFO module (the Erica Synths Drum Modulator) can achieve generative dark ambient. Seems unlikely but is really very straightforward. In this example it even sounds a bit like a thunderstorm. An Eventide Blackhole provides the obligatory big dark reverb and there's also some limiting in the DAW from a Fabfilter Pro-L.

Casio DH-100 Digital Horn Spotted in Until the End of the World

This one is in via swissdoc

"I was watching this 1991 movie recently, Until the End of the World, and spotted a Casio DH100 digital horn in a brief moment. See attached screenshot. The movie has some nice music in it (as you can see on the Wiki page). They kind of "Google" for one of the guys in the story and when one special search program is used, the sound which can be heard is one of the Waldorf Microwave presets.

I was watching the film at the movies when it came out in 1991 and this sound I did remember. The DH100 I did not remember, but it could be as well, it was only in the directors cut."

Shakmat Dual Dagger

video by Shakmat

"The Dual Dagger is a double-sided weapon, carefully sharpened to chop stereo signals. The module gives independent control over low-pass and high-pass cutoff frequencies, and an assignable resonance is shared on one control.

The Link function turns the dual filter into a band-pass filter, with control over frequency, bandwidth and band edges resonance! The module is carefully calibrated to share the exact same parameters on both audio channels and thanks to the pan function, it is easy to break up the cutoff frequencies of each side up, which leads to a whole new territory of stereo treatments!"
