"This Polaris 2 was fully electronically restored and is now in like new perfect working condition. And yes, of course the membrane panel that always breaks has been replaced with a brand new one so you won't have to worry about replacing it. We don't mess around here.

Here's what we did to this unit to make it perfect, along with some preventative stuff other sellers rarely do...because we want this unit to hopefully outlast others.

Replaced power supply electrolytic capacitors (future-proofing)
Reflowed some solder points as a preventative measure.
Cleaned unit inside and out.
Replaced membrane panel (we consider this a necessity even in the rare cases where they're fully working, as they eventually break - panel cost is $250 + installation labor, which is of course embedded in our price)
Cleaned and lubed all slide pots and levers.
Cleaned jacks.
Cleaned key contacts.
Removed original battery and replaced with new lithium battery (3v D type)
Recalibrated.
Replaced high and low output jacks.
Replaced operating system eproms with latest version 11 (originally was version 5)

This process took 11 hours of highly skilled vintage synth tech time, plus parts costs. The result is a perfectly working instrument that's ready to play, without having to pay another tech to do what we did and to wait months to years for another tech to do it."

"The K4 from Kawai can be thought of as a warm and fuzzy digital synthesizer. A sample-based digital synth, its sounds are those typically weird industrial type sounds that can still be useful in lo-fi, big-beat and trip hop music styles. The sounds are 16-bit preset PCM samples of acoustic instruments. However, unlike its predecessor the K1, the K4 adds a welcomed digital filter section. This truly makes the K4 more flexible, fun and useful for today's filter tweaking music effects!

The XD5 is an awesome drum synth module that has 256 waveforms, four of which can be combined to create a drum sound. It also has great resonant lowpass filters and envelopes for shaping the sounds and is excellent for techno, electro and industrial drums. For effects, a delay type effect is possible as well as a ring-modulator. It also has stereo outputs plus 6 individual outs for the studio pros. Mouse On Mars might use it.

The MM16 is a multi-purpose MIDI data processor with 17 front panel faders. Each of the sliders can be assigned for continuous controller information over any one of 16 MIDI channels, a "velocity mode" that uses the 16 sliders to become a "graphic EQ" for velocity data, and a system exclusive mode for transmitting system exclusive information to control individual synthesizer functions. Setups are included for Kawai K1, K4, K5, Yamaha DX7, and Roland D50. The MM16 can merge two MIDI signals, and can perform MIDI channelizing. You can also use it as a control surface for DAWS"

Moog Messenger - Ambient Sequence


video upload by Alba Ecstasy

"After a couple of 'unboxing' posts, I’ve been asked, by my friends, if it can sounds in my Berlin School style, or can make some ambient sounds.
So, here it is, on my second day with the Moog Mesenger, my sequencing style, PART ONE. I already made a few custom patches, (and updated it to the latest firmware - and now my volume knob works also for the main output! 0_o), so it’s gone rain with demos of it!

How does it feel? Like a Moog, of course: sturdy metal enclosure, no flimsy knobs, great keybed.
🎹 Want some ambient patches?! 👉 https://www.albaecstasy.ro

My opinion: grab one while the price is low, you won’t regret!
At least, Moog never drop in value!
Tell your wife, your girlfriend, your mother, that is an investment!"
