The caverns of hell | Prophet 08 soundscape

video upload by MIDERA

"I think the Prophet 08 is the one of the best DSI synths (my opinion is incoming). It's better than the REV2 for sure, which seems to share a hardness with the Prophet 12. A stiffness? I don't know. It has something I just don't like. The Prophet 08 and Poly Evolver seem to have been saved of this strange sensation. However, the Poly Evolver, specifically MY Poly Evolver, has been a bit problematic since I got it. First, the encoders were bad, so I needed to use deoxit on them. After 4 months, I needed to do it again. However, I decided to replace all of the encoders with 'clicky' detented encoders, the correct ones as described by Sequential via email, since they no longer had the potentiometer edition boards available. I spent about 10 hours replacing all of the encoders. What I learned was that the encoders actually take 2-4 clicks to make a change. This is frustrating because I don't think it is the correct encoders (DSI has not admitted this to me, stating that these are correct). Either they have different number of detents or something about the specifications are wrong - or it's right and they never fixed how the OS views the detents. Either way - it annoys me, making the interface frustrating.

As for the REV2 and Prophet 12, I just never got or never get tones like these. Audio Mod acts very differently in the P12 than the P08 and PE. I don't know why, but they are very different.

Anyway, I do wish I had the regular PE edition of the Poly Evolver... but I'm tempted to just sell it, because I'm too annoyed with myself and the amount of work I did to make it almost as frustrating as before and the Prophet 08 is a joy to use. I could sit in front of this thing for hours and play it. It just does a lot of things right. I wonder who on the team was working there when the P08 came out, and if they left afterwards. I thought the next thing out was the Prophet 12... I don't know.

Sequential Prophet-5 Demos by Timm Johannes Brockmann

video upload by Timm Johannes Brockmann


1. Sequential Prophet-5 | Valhalla Supermassive
This is a quick improvisation to demonstrate the majestic side of the Prophet-5, soaked in the Supermassive reverb from Valhalla.
2. Sequential Prophet-5 | Roland JD-990 | valhalla supermassive --- Glassy shimmering evolving pads
In this video, the Prophet-5 is played and sends it´s MIDI notes via the MIDI Out to the Roland JD-990. You get a beautiful layering with a shimmering pad from the JD-990.
3. Nord Piano 5 || Sequential Prophet-5 || LAYERED
In this video, the Sequential Prophet-5 is adding some notes to a repetitive pattern on the Nord Piano 5.

Recorded in Logic Pro X with additional effects.

Hacking thru the instrument for the first time.

Limited tweaking but very pleasant analog sound of all instruments.

Unfortunatley as you can see was the sturdy RITMOBOX damaged on transport due to back packaging. The shaft of the volume pot was bent. Fortunately the RITMOBOX is a solid beast with its pots screwed to the surface. Otherwise the pot would have broken out of the board. As a result of the shock 4 multipurpose button caps fell off their sockets. A hefty violent shaking is necessary that they leave their positions."

Modular Synthesizer Voltage Controlled Amplifier

"Continuing the build by adding the Voltage Controlled Amplifier and tying it in with the ADSR and GATE. The Q108 and Q158 are both listed on the website with specs etc."

Allemande (Disting EX's Poly Wavetable)

video upload by Electrum Modular

"I've been working on the Allemande from J. S. Bach's French Suite No. 4 in E-flat, BWV 815, and was frustrated that I couldn't hear all those long, held notes. Rather than select one of its cheesy organ presets, I decided to connect the piano to my (smaller) Eurorack case. It worked well with all of the polyphonic algorithms on the Disting EX, but the Poly Wavetable gives you the most options for using keyboard velocity not just to control volume but also to shape the timbre - via filter cutoff, wavetable position, etc. I set the envelope times/levels/curves so that the held notes would remain audible, but in the background.

Here is how I connected the piano to the modular: USB Midi cable - DOREMIDI midi host - 5-pin MIDI cable - TRS adaptor cable - MIDIXO breakout, which connected to the rear of the Disting via 4-pin ribbon cable. If there's a more direct way to connect them, please let me know in the comments!

New Gimme Some Snare Drum Module from BLM

video upload by flavio mireles

Modules used in the demo:
BLM Scope
Acid n SOns VCF
Braids Blue Lantern Version
Arturia Beat Step Pro for Sequences
LML VCO for modulation

Available on Reverb

MODEL: BLM GS-SNARE, Gimme Some Snare

WIDTH: 16hp

CURRENT: +107mA,-97mA

Price $245.00

What does this do?
This is a mini analog synthesizer that produces snare drum sounds. Inspiration was taken from the 5U Cor Synth DR02 module. Only the flow chart was studied and used to create this BLM product. VCV Rack was also used to simulate and test the building blocks.

Most of the circuits contained in this product are from other blue lantern module designs.

Some of the building blocks:

-2 1V/Octave Triangle Core VCO's
-2 Sine Wave Shapers
-4 Envelope Generator
-White Noise Generator
-High Pass Filter
-Tone Filter
-2 VCA's

The goal of this module was to recreate some of the more exotic electronic snare sounds.
Your not getting another Roland 'TR' module with the Gimme Some Snare Drum. All the building blocks contain
full analog circuitry, like OTA chips, and Op-amps. No vintage transistor based (Bridge T Oscillator) circuits are used in this product.

The best description I can give you inquiring what the kind of snare drum sounds this module can produce is something comparable to: an Electribe Korg ER-1, Simmons Snare Drum, and the Mattel Synsonics.

Non-Linear Memory Machine by Holocene Electronics

video upload by Stazma

"Today I'll be showing you the Non-Linear Memory Machine (NLMM for short), a stereo digital delay with pitch, freeze and granular functions. I had a great fun trying out this module, many thanks to @holocene_electronics for sending this to me to make this demo."

via Holocene Electronics

"The Non-Linear Memory Machine is an audio buffer device. Set to a short buffer length, the NLMM is capable of creating alien phaser sounds to reverb and delays. While in a longer buffer length Frippertronics / time lag accumulator style looping is available.



Controls the delay time of the signal. The delay time can span from a few milliseconds to up to 15 seconds, depending on the buffer length. Unlike analog delays like tape or BBD delays, when modulated the pitch of the signal does not drift. Instead, it compresses and expands time in interesting textures via a custom time-stretching algorithm. When activating Freeze via the freeze switch, this knob functions as the play head's position within the buffer.


Randomizes the Time/Scrub control, adding random jitters to the position of the playhead and diffuses the signal in a way that can be utilized as a pseudo reverb effect. (experiment with the Time/Scrub knob and Feedback knob to create glitchy reverbs.)


Pitch shifts the signal +- 1 octave. This knob snaps to perfect 5ths and an octave but you can dial it in between intervals. Nice crunchy aliasing when pitch shifting is applied.


Crossfades between the dry signal and processed wet signal.


Feedbacks the delayed signal back into the input. Set it up to 4’o’clock when in Medium or Long mode to experiment with TLA or Frippertronic style looping.


Switch between delay ranges according to the list below.

\SHORT – 20ms ~ 320ms

\\MEDIUM – 320ms ~ 1.6sec

\\\LONG – 1.45sec ~ 15sec


The Freeze switch acts like an infinite sustain pedal, but you can also scrub through the buffer with the time/scrub knob when activated. Red means recording, and unlit means the buffer is frozen / not recording. Great for practicing scales or droning away."

Roland System 100m 160 SN 00002

via this auction

"This is one of the rarest if not THE rarest System 100m production run module Roland made. This is serial #00002. I have no idea how this works, and based on online discussion, it is a bit of a mystery. Yes, the price is $5000USD, but the price of the 165, 172, 173,174, 182 have all gone sky high in the last few years. I figure this is worth more, just based on rarity alone. This is a collectors item, not something that I figure is actually usable in today's world. My exact module was featured in '50 years of Roland History' book."

Arturia Matrix 12 V - Sound Bank '85

video upload by Polydata

"The last great analog polysynth. The Oberheim Matrix-12 was a masterpiece of sound and engineering, and the Arturia Matrix-12 V is the only plug-in emulating this landmark instrument.

A bank of 30 patches drawing inspiration from synthesizer sounds found in documentaries and library music from the late 70’s and early 80’s. The goal was to highlight the beautiful and unique sound of this instrument. I've always loved the tone of this plug-in - it has it's own sonic character while still sounding like an Oberheim, and it's unlike anything that came before or after it.

Recorded completely dry with no external effects or processing.
