"Join Ryan Hawkins and me for an in-depth look at an extremely rare ARP 2600 called the "Blue Marvin". It was the first ARP 2600 prototype created in 1971 before the later gray faced Tonus versions of the instrument were made for sale to the public. There are a lot of quirky physical aspects to this beauty since it was never really completed for final production, but in spite of that, it sounds magnificent! In particular, there is a type of harmonic distortion that it delivers only to be found on the original R.A. Moog modular synths from the late 1960's through the early 1970's.

You'll also hear the back story about how it was found in a post office, changed hands and then how it was restored by Ryan. We'll explore the front panel by comparing it to the first production Tonus model and also give you a Hands-on demonstration of the compelling sounds that it delivers. All music in this video is composed and performed by Ryan.

ARP 2600 Blue Meanie S&H 01

Published on Jun 30, 2013 AudioCentralMagazine·152 videos

"The (ultra) rare ARP 2600 Blue Meanie/Blue Marvin is under control of S&H module: EGs are fired from S&H Clock; VCO1, VCO 2 and VCF are S&H modulated. Audio signal goes straight into 2600's spring reverb. A copy of the VCA out signal (dry) is hard switched left/right with Electronic Switch. A great synthesizer, pretty different in sound from the standard 2600 B/W and B/O."

Ambient Improvisation Using ARP Odyssey & Blue Marvin 2600 Inspired By Jean-Michel Jarre

video upload by Piotr Garbaczonek

"Thanks for watching!
Made a little improvisation piece using the Blue Marvin 2600 and the Korg/ARP Odyssey. I only have one input on the UAD Volt interface, so I am running the ARP Odyssey output through the Blue Marvin's Ring Mod Input on the VCA side. It seems to be working quite well, allowing me to still use Blue Marvin's 3 oscillators in conjunction with it, so that's quite nice. The eurorack modules are used to control both the Blue Marvin and the Odyssey. From clocking, sequencing, modulation, and filtering. I wanted to replicate the EMS Synthi used countless times by Jean Michel Jarre during his live performances as a crazy laser machine. Combined with a smooth chord drone on the Blue Marvin and a bit of its internal spring reverb, it is a pleasant little journey. Cheers!

Custom MacBeth M5N "Blue Meanie" / "Blue Marvin"

via Ken MacBeth:

"Hi Matrix! ...well to continue with the custom panel thread- a prolific german client asked to have 2 M5N synths built for him- but with a special blue color that I ordered in- this color was swatched against the color type of the very first ARP 2600s. We discussed whether or not they originals were called 'blue meanies' or 'blue marvins' - maybe the viewers of the matrix synth blog know this stuff! I am currently offering direct sales of two Process Red M5Ns (...there will be a fire in the disco!) that go as a pair-both hand built by myself, and not the factory I'm using- there is a premium for this- but interested parties can enquire- pics to follow soon. Best To All- Ken Mac."

Via this post: "The very first model 2600 was produced in early 1971 and is known as The Blue Marvin. It has mistakenly been called the "Blue Meanie" but according to Alan R. Pearlman, the Blue Marvin is so named after Marvin Cohen, head of engineering at ARP at the time."

"The Dreadnaught Factor" - Akai MPC X + Behringer 2600 Blue Marvin + ASM Hydrasynth + MINIFREAK...

video upload by Patrick Manderson

"'The Dreadnaught Factor' was recorded live early Saturday morning on January 21st 2023 using a MIDI sequencer, a room full of synthesizers and drum machines. Four analog mixers were used with a rack of outboard effects and mixed stereo. Mixing and automation was controlled by the sequencer directly to the synthesizers. The final reorded required manual muting of the of mixer channels to suppress the noise coming from some of the devices including the Korg Minilogue. The video was taken afterwards.

"The Dreadnaught Factor" was inspired by the box art of an early 80s video game for Intellivision. It featured a number of spaceships on a blue background much like the 2600 Blue Marvin featured in this music. The melody and chord arrangement originated from a short piece I created several years ago and later merged it with a small piece of unfinished music titled "Driod Mischief". I was pleased how the two sounded when arranged in this way. I look forward to finishing "Droid Mischief".

The Hydrasynth plays a few different roles in Dreadnaught, even doubling up with the BassStation adding filter modulations to the bass parts [3:23].

The Korg MS2000 never disappoints when you use its modulation sequencer and its charasmatic digital distortion. Several parts were played, twisting and swirling in the stereo field. Modulated tremolos off-rhythm and hypnotic.

Korg Minilogue XD has so much range - such a wide sweet spot of sound. Especially when you use the digital user oscillators. Resonating plucks and unnatural reverbs works well for my tastes.

The Behringer 2600 Blue Marvin and Model D is featured in the "Droid Mischief" part at [2:58].
The notes were played over MIDI. Volume modulation was controlled with CV from the *Akai Pro MPC X*.
The Model D ran through the inputs of the Roland TR8s for its Phaser effect. The TR8S did nothing else.

There are a few dark pad patches I re-use often on the Oberheim Matrix 1000 playing disonant chords throughout.

The Elektron Analog Rytm MkII provides most of the rhythms. Each of its 12 voices run on its own MIDI channel with a full complement of continuous controllers. Lots of CC modulation was used on some of the voices. The internal sequencer was not used. All notes and automation comes from the *MPC X*.

Arturia's MINIFREAK layered in a few bits throughout and is featured at the very end [6:11]. Macros were modulated from the *MPC X*.

Korg's Radias is 4 part multitimbral. On part #4 I keep a carefully curated drum kit synthesized with noise, sines and filters - mixed with some of the built in drum samples. Part #1 featured a vocal "ah-ha" patch [3:01] using one of the vowel waves, a formant insert effect and careful modulation of its dual filters.

My favorite guitar pluck patch on the Korg EX-8000 makes an appearance.

At the center of it all, the MPC X seemlesssly connects to everything and manages to keep all devices in perfect sync. As mentioned before - meticulous editing of MIDI events is a breeze and very comfortable over long editing sessions. Approximately 21 tracks were used including Control Voltage for the modulars.

Ambient sounds of outer space | Neutral Labs Pip & Nijel, Blue Marvin, Deckard's Voice | (20 min)

video upload by Piotr Garbaczonek

"Thanks for watching!
I made a 20-minute soundscape video that sounds like the 70s and 80s depiction of music from outer space. Everything is coming out of the Blue Marvin's stereo output, as I don't have any VCAs. Here is the list of modules I used and how they play into the function of the piece:
- Neutral Labs Pip (Clock and CV output)
- Instruō Harmonàig (Quantizer (random melody generator in A Phrygian))
- Instruō/Divkid øchd (overall modulation to a bunch of parameters around the patch)
- Black Corporation Deckard's Voice (Main oscillator on the eurorack side)
- Serge by Random*Source Variable Q VCF (Filter to which Deckard'd Voice is connected (VC F and VC Q parameters modulated by øchd))
- Neutral Labs Nijel (Drive effect for Oscillator 3 in Blue Marvin 2600's Sine Wave, the amount is modulated by øchd's slowest LFO)
- Behringer Blue Marvin 2600 ( 1st and third oscillators, various modulations and internal spring reverb)

In Ableton, I have Valhalla Shimmer on, Other Desert Cities by Audio Damage, and some light EQ and compression.

Rare ARP 2600 Blue Marvin Jam (w/ Cameron Graves)

video upload by Anthony Marinelli Music

"It's always fun to perform with my good friend Cameron Graves aka "The Planetary Prince". I was introduced to Cameron and his brother Taylor Graves in 2008 by Jada Pinkett Smith when we co-scored her film, The Human Contract. We've remained friends and musical brothers ever since. We hope you enjoy this music that we created right before the cameras started rolling . We intend to make more of these synth jam videos in the near future.
We're playing the solos on an extremely rare ARP 2600 "Blue Marvin" which was a prototype for the Tonus ARP 2600 that actually went into production. The rest of the synths include a later model gray faced ARP 2600, an orange faced ARP 2600, the Korg ARP 2600 M, Moog Minimoog, Korg MS-20 and ARP Omni String Synthesizer. The drums are performed by my engineer Ben Rachlis on a vintage LinnDrum the he is processing through The OTO Biscut, Bim, Bam and Boom.
Please remember to like and subscribe to these videos. It would mean a lot to me and my dedicated and enthusiastic crew. Thank you to all for your support and inspiring comments!

"Thanks for watching!
Made this interesting patch on the Blue Marvin 2600 by Behringer, and with some help from 2 eurorack sequencers: 2 Qu-Bit Blooms 😁.
The audio is just stereo out from Blue Marvin directly. Some reverb and delay in Ableton, and the UAD Pultec EQ as well as the Studer A8000 tape machine on the Master.

"EXPERIMENTAL ELECTRONIC MUSIC EXPERIENCE" - PIOTR GARBACZONEK (FULL LIVE PERFORMANCE AT BERKLEE)

video upload by Piotr Garbaczonek

"Thank you all so much for watching my performance!
Date: December 14th, 2021
Location: B54 at Berklee College Of Music, EPD Labs
(Electronic Production and Design)

This show was my showcase as part of my EP-491's final project for my major. Aside from finishing a 5-track EP in a semester, I also was preparing this set for a very long time along with all the music. I decided to pull in a few songs from my previous EP: Experimental EP, Vol. 01, to spice up the performance a bit. The songs included were: Conformity, as the first song after the modular-only section; Time, which was the song at the end of the set with the QR code to my social media links. Everything else was songs from the past 4 months.

All the visuals were edited beat by beat, a song by song in Adobe Premiere Pro, and then rendered and then put into an Ableton Session to be played in a specific earlier-defined order.

I divided the show into 2 sections: Ambient Experimental, and Glitch Experimental.

The first part included rhythm-free elements only and primarily played on various modular synths, up until the 13th minute, where modular synths were supporting all the songs played in order.

The second part included various drum elements, as well as glitch music and frequency spectrum bending polyrhythms.

In terms of gear used, I used my Zoom L-12 Multitrack Mixer, to record all of the individual inputs directly into Ableton. Ableton had different effects in the effects chain of each track depending on what was necessary for each one.

For all the weird clock-driven, laser-sounding fast atonal sounds, I used the CMS MR-15 Modular System based off of the ARP 2500. For some chords and mild sawtooth progressions, I used the Blue Marvin 2600, which is based on the ARP 2600 with built-in Spring Reverb. The Blue Marvin was sequenced by one of my Qu-Bit Bloom Sequencers running in the minor key.
The master clock for everything was the ALM Pamela's New Workout, and it was clocking the CMS, Blue Marvin, 2x Qu-Bit Bloom, Qu-Bit Chance, Moog Subharmonicon (which was doing all the background pads), and Mutable Instruments Rings.
There were various other sequenced sounds, including Mutable Instruments Plaits as a 32-step arpeggio in minor, as well as Mutable Instruments Rings, going through Clouds as a textured effect.
Cwejman VCO-2RM was running through Qu-Bit Tone's LPF, and directly out as a very low analog sub.
The E340 Cloud Generator was my analog Wavetable synth, which I played directly on the Arturia Keystep MIDI-Controller, by sending it pitch information only, and running it through MI Ripples, and out.
The Instruo Arbhar was running in stereo mode, and that one was doing all of the tapping and scratching noises in left and right channels. It has a built-in condenser mic, so I was tapping it on the spot to fill up some space in transitions for some ASMR effects haha.
That's pretty much it in terms of gear used.
If you have any questions about anything, please don't hesitate to ask in the comments. I will happily answer.

Again a huge thank you to Wiggz for doing some cool action shots while I was playing.
This is his YouTube channel: https://www.youtube.com/channel/UCItL...

And thank you to Dr.B for being an amazing professor, and leading me through the last stretch of my EPD Journey, as well as opening new doors for me for the future.

Cool Ambient Patch on Blue Marvin 2600 & Eurorack ( Instruō Tágh & Harmonàig; Elements & Ripples)

video upload by Piotr Garbaczonek

"Thanks for watching!
Made a cool experimental patch using the Blue Marvin 2600 and some eurorack modules below it on the TipTop Audio Happy Ending Kit.
The modules I am using are:
- Instruō Tágh (Sample and hold out to Harmonàig)
- Instruō Harmonàig (Quantization and gate output to MI Elements)
- Instruō/Divkid øchd (Modulation to various places)
- Mutable Instruments Elements (Main Stereo Oscillator, first out goes through Ripples and then out; second out goes through 2600's filter and then out)
- Mutable Instruments Ripples for low-pass-filtering one of Element's outputs
- 2hp Mult for splitting stuff

After going out stereo into Universal Audio Volt interface and into Ableton Live, it goes through Other Desert Cities by Audio Damage, a very cool effects processor, as well as some shimmer. I am also using Blue Marvin's built-in spring Reverb to some extent.

ARP 2600 with MIDI

via this auction

Details:

"Much of the following info can also be found at discrete synthesizers.

2600:
The very first model 2600 was produced in early 1971 and is known as The Blue Marvin. It has mistakenly been called the "Blue Meanie" but according to Alan R. Pearlman, the Blue Marvin is so named after Marvin Cohen, head of engineering at ARP at the time. It came in a bright blue aluminum case with a funky and fragile wooden enclosure. It used an entirely micro-chip based voice path but the chips they used wound up being highly unreliable, although they sounded great! Only a few of these were made (approx. 25) and they were mostly built in a garage.

2600C:
Next, the factory produced 2600C Gray Meanie (pictured above) appeared in 1971 and can be identified by the rectangular 'ARP' logo on its right speaker grille. About 35 of these were made.

2600P:
Later in 1971 came the 2600P V1.0 which featured the same metal case (housing the same electronics as the original models) now enclosed in a much more roadworthy suitcase-style enclosure (similar to the pic below). In 1972, ARP switched out the unreliable (Teledyne) VCO chips for the model 4027 and 4027-1 (National Semiconductor) VCO chips in the 2600P V2.0 and 2600P V3.0, respectively. These new VCO chips sounded weak and nowhere near as good as the originals. A new duo-phonic keyboard (3620) with LFO was introduced with the 2600P V4.0 in 1974. The 2600P V3.0 and V4.0 models are denoted by the "G-clef" ARP logo and are the most common models out there with roughly 1700 2600P's produced during 1971-1974. Unfortunately, further changes to inferior parts were just around the corner. The Model 4012 filter used in the all the 2600's through 1976 used a design that was a copy of Moog's patented ladder-filter design. This led to a law-suit between Moog and ARP which forced ARP to design their own filter for their next version.

2601:
The Model 4072 filter, a four-pole low-pass designed to replace the original 4012 was widely considered to be faulty. The frequency response of this filter only goes to about 12kHz, giving this model a duller sound than models with the Moog style 4012 filter. The early 2601 V1.0 models were still using the disputed 4012 filters during 1975-76. In 1977 ARP started using their new 4072 filter in the model 2601 V2.0 with the modern orange-on-black design (pictured below). Around 1978 ARP unleashed a whole new line-up of their synthesizers using this new orange-on-black look. These were produced from 1977 through 1980. Very late 1980 versions of this model featured un-potted submodules, making them easier to maintain (but they are more rare).

There were also three versions of the remote keyboard: The Model 3601, which is a very rudimentary version with just Portamento and Tuning controls. The Model 3604 is similar but adds adjustable scaling and was used until 1974. The duo-phonic Model 3620 (pictured at top and bottom) which adds a dedicated LFO, latching and some other very useful features was introduced with the 2600P V4.0, and used with all subsequent models from 1974 to 1980."

First Demo Video & Pics of the New KORG ARP 2600

Uploaded on Jan 9, 2020 GAK

KORG ARP 2600 FS posts

Update2: The announcement is up here.

Update: Looks like the video was changed to private. Good reminder to be checking the site often - to catch things before they get pulled. :) BTW, the video stated the new 2600 is based on the first version of the ARP 2600. That is technically incorrect as the first version was actually the Blue Marvin/Blue Meanie. You can find two videos of one here, and some pics in various archived posts. There was also a Grey Meanie. From that link: "First was the Blue Marvin about 20 of these were made next was the Grey Meanie 35 or so were made". This new 2600 has the design scheme of the first major runs of the next 2600. Thanks goes to @AzevedoAudio for the reminder!

"The new Korg 2600 Arp is here!
Luke pops in to Demo this beast."

Note the "sequencer" is a programmable arpeggiator:

"3620 Keyboard While faithful to the original design, the functionality of the 3620 Keyboard has been greatly enhanced for this limited ARP 2600 release. The 3620 Keyboard contains 49 full-size keys, aftertouch, portamento, and is also duophonic, allowing two keys to be played at once – Single or Multiple Triggering is available. In addition, the duophonic keyboard can use an optional foot switch to lock the interval between any two notes, without retuning the oscillators during performance. Vibrato can be added via a dedicated circuit controlled by aftertouch, or by the onboard LFO (Low Frequency Oscillator), using any of three available waveforms. Most noticeable is the addition of a flexible Arpeggiator that allows a user-defined pattern to be manually sequenced and played back. Still present are the original Pitch Bend knob and the Two Octave Up / Two Octave Down Transpose switch. Connecting the keyboard to the main unit now uses a secure eight-pin din cable.

Processing Powerhouse The ARP 2600 reveals its modular nature by the unique assortment of valuable, esoteric, and individually patch-able modules it contains. To begin, there are a set of parallel-wired Multiple jacks that enhance the patching possibilities – allowing the same control signal to be sent to multiple locations, for example. Three independent Voltage Processors provide scalable control voltages, or can act to attenuate any control signal. Use the Lag Generator to delay the start of any control signal. The Noise Generator is tunable to deliver White, Pink, and Low-Frequency noise, plus everything in between. A series of three Inverters can reverse the polarity of any signal. The Electronic Switch can be sync’d to either the internal clock or any external clock signal, as can the Sample & Hold rate. Most importantly, the Arp 2600 includes a dedicated Preamp and Envelope Follower for processing an external audio signal."

ARP 2600 with CMS Mods / Upgrades

images via this auction
"ARP 2600 semi-modular synthesizer, with full complement of CMS modifications and upgrades.

This auction includes the 2601 Console (s/n 26010788) and 3620 Keyboard Controller (s/n 36200788). Not only is this 2600 in outstanding cosmetic and functional condition, the numerous modifications and upgrades performed by Phil Cirocco at C.M.S./Discrete Synthesizers make this a truly phenomenal instrument. Here is a list of the work performed, with descriptions from the CMS web site:
AUDIO PATH UPGRADE PACKAGE
This mod replaces all gain stages in the 2600 console with audiophile grade components for crystal-clear highs and a deep low end, while still maintaining the distinctive character of the 2600. Upgraded sections include: lag processor, voltage processors, reverb stages, preamp, VCF mixer, output mixer, output buffers, etc. We also fix the annoying VCA thump. Noise in the reverb section is reduced by 35%. Filter headroom is increased by a factor of 2! Stability and sound improvement guaranteed. Later model 2600s (almost all wood / tolex 2600s) use inferior sounding gain stages that severely impede the true sound of your 2600. Earlier 2600's (Blue Marvins and Gray Meanies) use "high slew rate" chips that sound much clearer. Restore your 2600 back to the specs that the original ARP engineers intended! Don't be fooled by imitations from "noob techs" or DIY attempts. If the Audio Path Upgrade is not performed correctly, it can become unstable and lead to high frequency self oscillation of all the amplifier sections!

MOOG STYLE FILTER MODULE - 4012cx
The 4012 filter was used from 1971 (blue Marvin) to the middle of 1976. If your 2600 is a gray face, It probably utilizes the 4012 module. The 4012 is a ladder type filter using discrete transistors. The original 4012 made by ARP is prone to instability. The 4012 replacement filter by CMS is guaranteed stable yet uses the exact circuit that ARP used. Better quality components and personal attention to craftsmanship yield a filter of superior sonic characteristics! See the Sub-module section for more info.

VCA MODULE UPGRADE - (4019)
If your VCA module is unencapsulated, we can give it crystal clear highs and a deep low end. Also provides lower distortion and a faster slew-rate. If you have an encapsulated ARP VCA, this upgrade is not available, but improved unencapsulated replacement modules are available, see submodules page, model 4019cx.

POWER SUPPLY UPGRADE
The power supply in your 2600 is about 20 to 30 years old. Chances are that your power supply is not up to spec. This can result in excessive noise, ripple, and instability. This mod replaces your unit with a high power, highly stable, military spec power unit with remote sense regulation. The overall sound quality and oscillator purity are noticeably improved. Rebuilt ARP units are available for 125.00 (50.00 core charge).

17 INCH REVERB TANK
Ever wonder why later model 2600s have such a lame reverb. Later model 2600s use smaller reverb tanks with a shorter delay time than earlier 2600s made by ARP. The only reason I can find for this change is economic. Our brand new reverb tanks use 6 springs, counter wound and placed in parallel for a rich, full sound. This mod restores your reverb sound back to the original "Blue Marvin / Gray Meanie" configuration.

1/4 INCH LINE LEVEL JACKS
Professionally installed 1/4 inch Switchcraft jacks at line level (designed to interface with your studio mixer etc.) on both main outputs, VCA output, and preamp input. 4 jacks total.

SYNC SWITCHES
Two independent miniature toggle switches that sync vco-2 to vco-1, and vco-3 to vco-1 This setup enables dual sync (two separate harmonics) if desired.

ENVELOPE GENERATOR RANGE EXPANDER SWITCHES
Miniature toggle switches that provide 2 additional time ranges for the attack, decay and release time of the ADSR generator and the attack and decay time of the AR generator.

VARIABLE VCF KEYBOARD TRACKING
The filter tracking on a 2600 is fixed at 1v per octave. This is quite limiting especially if you are shooting for natural textures. This mod provides a miniature rotary potentiometer that adjusts the tracking ratio from 0 to 1v/octave

LED INDICATORS
providing visual feedback on both E.G. outputs (red), s/h clock (green) and envelope follower (yellow). Requires power supply upgrade.

24Db DUAL MODE FILTER - MODEL 2621
The one key element missing in a 2600 is a highpass filter with resonance and associated coupling circuitry. The CMS 2620 is a dual mode, 24Db (Lowpass/Highpass), discrete, transistor ladder filter from the CMS 9000 series modules, Installed in the left speaker section. This original CMS design features a beautiful "raspy" resonance. Complete with anodized face plate, high quality controls, 1/8 inch Switchcraft normalized patching. Special switch links both filters in your 2600 together for a truly remarkable sounding bandpass function (24Db x 24Db). The resonance on the highpass function is also very unique and distinctive. Requires power supply upgrade. Now comes with voltage controlled resonance.

VCO / 4 CHANNEL MIXER / INVERTER - MODEL 2627
Installed in the right speaker section, this VCO utilizes the same exact circuitry used in the other VCO's in your 2600 to assure exact tracking and pitch stability characteristics. All four waveforms are available as well as pulse width modulation. Low frequency mode and normalized patching are also provided. The mixer section serves as a high quality audio mixer with the inputs either normalized to all 4 outs of VCO-4 or externally patched. The mixer can also be used as a voltage summer or inverter. Requires power supply upgrade.
In addition, the following mods are present:
• The AR has been converted to an ADSR for even more CV potential;
• All three oscillators have been fitted with -1/0/+1 "octave" switches. This switch will transpose the oscillator by the amount predefined by the "Interval" pot (up to one octave)
• An additional set of multiples have been added in the lower left, now giving you 2 x 4 mults;
• Voltage Processor sections 2 & 3 have positive outputs available as well as the conventional negative;
• External trigger input for the Sample & Hold."

"Clair de lune" - 3-voice synthesizer rendition: Moog Sub37 CV, ARP Odyssey, Blue Marvin 2600

video upload by Piotr Garbaczonek

"Thanks for watching!
I split Clair de lune into 3 monophonic voices, and ran each voice through a different synth, using the MOTU midi express 128. The first voice was the Behringer Blue Marvin 2600, the second voice was the ARP Odyssey, and the 3rd Bass Voice was the Moog Subsequent 37 CV. Just a little experiment. Let me know in the comments what rendition you want me to do in the near future. Cheers:)

video upload by Piotr Garbaczonek

"Thanks for watching!

Happy Valentine's Day!

Did this rendition of 'All of Me' by John Legend on my Behringer Blue Marvin 2600. I was sending the MIDI from Ableton through the Intellijel µMIDI eurorack module. Melody layer was also modulating the PWM of the with the Mutable Instruments Marbles. If you have any questions about the patch, let me know in the comments. Cheers!

ARP 2600 Blue Meanie Funzionamento & Comandi Principali

Published on Jul 3, 2013 AudioCentralMagazine·157 videos

"Una panoramica veloce sul funzionamento dell'ARP 2600 Blue Meanie/Blue Marvin; rispetto al 2600 "normale" ha una risposta più aggressiva nei confronti dei livelli audio e manca del Fine Tune nella regolazione di Cutoff Frequency. Manca anche, particolare secondario, il multiplo a quattro vie per la triplicazione dei segnali. Una macchina spettacolare, rarissima e potente."
