12/13/23 (filter opening, pitch) Roland Jupiter 6 + Akai ME20A + Alesis Midiverb II (46)

video upload by Cfpp0

"Added the Alesis Midiverb II to the Roland Jupiter 6 and Akai ME20A window. It’s a bloom machine, but it’s great at reversed effects, like this reversed delay preset #46. The Midiverb II is being used in mono here. I still don’t really understand how the ME20A turns chords into these odd sequences in sequential playback mode, but when I switch to up mode it makes a bit more sense."

"Professionally serviced. All potentiometers were cleaned and now work as they should. Muting transistors replaced. Battery replaced. All voices tune up just fine using the onboard autotune function, and this unit sounds amazing and is ready for its new home.

Note: The keyboard aftertouch on this unit and the other we compared it to is imperfect, meaning the response can vary from key to key using its built in keyboard. (This one actually behaved better than the other)"

"This unit is from the last batch (built in 2010) by Alesis.

Serial A10806045701015

It was never gigged, only used in the studio and taken great care of.

It is truly fully functional (which appears to be rare with these).

- the ribbon works

- all knobs/buttons work

- all 16 voices work fully

It was serviced at Audio Design and Service Inc in Burbank in Jan 2022

At the time one of the headphone output amps was dying, which was a simple fix. This is the only issue I've ever had with it. I had it given a full once-over at the time.

An ex-colleague of mine was a tech at Alesis when the A6 was being sold, he pointed me to ADS as the owner/one who serviced it was an A6 tech as well and thus very knowledgeable about these.

I would call it Mint condition, except some minor paint-only scratches in the rear and discoloration of the lettering on the rear which is a tad yellowish vs how it was new."

DAWlessly Recreating Café Del Mar on mostly 90s synths

video upload by Bleeps and Boops

"Sadly I don't own any of the JP8K or Access Virus synths, so most of Ferry Corsten's output is out... as is Xpander!

Synths are the Nord Lead 2X, Roland JV1080, Moog Sub 37, Yamaha TX81Z, plus the Akai S3000XL. Sequencing is on the Squarp Hapax, reverb is from the Alesis Quadraverb."

Inside the Prototype Alesis 6461 QS6

Here are ome pics of the inside of the prototype Alesis 6461 QS6 posted here, in via Mike. These pics have been added to that post as well.

Per Mike: "Looks like a 'nearly production' version as I see only 2 hand soldered jumper cables. Everything else looks neat. Even the PCMCIA card slot is there, even though there is no external plastic guide/surround."

Note the ALESIS S6 MAIN PCB REV. x5 dated 5-23-95 printed on the PCB in the 2nd to last image below, followed by a sticker found inside dated 9-5-95. It likely fell off a chip.

The QS6 was released in 1996, per Wikipedia: "In 1996, Alesis introduced the first of their QS series synthesizers. The first of these were the QS6 61-key synth and the QSR rackmount synth. Following these in quick succession were the QS7 76-key synth and the QS8 88-key synth"

Update via Mike: "Info from one of the original Alesis engineers around the time says that this was the only prototype made. They had done tests 'out of the box' but only 1 physical 6461 was made."

"This is one of the greatest analog poly-synths of all time. 2 Oscillators, each with sub-oscillator provides a ton of thud and weight. The filters (Moog and Oberheim) are also faithful to their original namesake. If you cannot get a Moog One, this is the next best thing at half the price.

All 16 voices tune and track without issue throughout several days of testing

The LCD screen is nice and bright and contrasty, even all the way through, with no dead pixels

All knobs are free from jumpy-ness that these go through and have been cleaned and lubricated

It has been loaded with Factory presets and User banks

It has 1.40.12 the last firmware update before beta. This .13b firmware can be provided if needed.

Condition is near-mint, only due to a slight crack in face panel around all 4 corners of the screen, but is barely visible."

FVS vs reSEMble Nov 2023

video upload by Randy Piscione

"Another demo of the PM Foundations reSEMble, four of them (https://www.tindie.com/stores/pmfound....) This time, I've duplicated a patch on the FVS and the reSEMbles. I was going to do a dry video but figured I'd do a little tune. At the beginning you can see my left hand playing the FVS while the right hand plays the reSEMbles, and since they alternate for a brief time, you can compare the two instruments. Together they sound amazing! I imagine this is what it's like to play a dual manual eight voice. There are also some ARPs, a Rhodes, a Kurzweil K2600XS, and an Alesis SR16 adding support."

Tim Shoebridge: My Search Is Over

video upload by Tim Shoebridge

"My search for an amazing sounding, powerful, flexible analogue poly synth is now over. And to celebrate, here is my own little tribute to the Alesis Andromeda A6 (ASICS), long may it continue to power on!!"

First time messing with the aeles a6 synthesizer #vintagesynths #a6 #band #denver #studio #synth

video upload by Chromesthesia Music Library

Alesis Andromeda A6 of course. I keep the titles as posted for the most part as that is how it went live to the world, and to be able to search for videos by title in the future.

Alesis 6461 QS6 Prototype?

This one is in via Mike who just picked it up. I'll see if I can get some better pics when he has it. Until then, if anyone is familiar with it, leave a comment. I search for Alesis 6461 only brings up this blurry image.

Update: new pics here.

Alesis A6 Andromeda 61-Key Polyphonic

"This Andromeda is actually in very good condition and all voices function and tune perfectly, but the Potentiometer #4 for PAN near the screen needs replacement as it is very jumpy so it changes the Pan parameter,and a few other pots are pretty fiddly as well and could do with servicing."

Alesis A6 Andromeda 61-Key Polyphonic Analog Synthesizer w/ Custom Dust Cover

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"According to my information, the serial number indicates a 2004 production.

If you’re looking at this, I probably don’t need to tell you the Andromeda is a true beast of a synthesizer. It has 16 voices of fully analog synthesis signal path, along a myriad of digital FX, 16-part multi-timbrality, and so much more.

Functionally, synth is in superb condition. All of the keys, knobs and buttons are tested and working with practically no issues. It’s not uncommon for Andromedas to have jumpy pots, and while going through each knob I did find two pots that experience some minor jumping, but it does not adversely affect operation. This may be remedied with contact cleaner but I’m leaving that choice up to the buyer.

Most importantly, no dead voices, all tune up properly.

Cosmetically the synth is also in excellent condition for its age, but does show some very minor wear and tear. For the most part, the synth looks relatively perfect if you aren’t inspecting it up close. The biggest flaw is some minor damage the right hand plastic end cap. Photo included.

The synth was professionally serviced by my technician in 2020 to resolve some volume output issues. The synth has a clean bill of health now.

Included with the synth are a power cable and custom leather dust cover by Stardust.

Additionally, I have a license for the only VST editor for the A6, which I’ll transfer to you after the sale."
