I have to admit its sat in the rack unused here in my home studio for 20 Years!!
Only problem is the two volumes sliders have broken off.They can still easily be moved using flat device and could be easily fixed.
Given how old this is I think its in amazing condition”

Crumar Stratus

“Crumar Stratus Vintage 6 Voice Polyphonic Synth/Organ. Condition is Used.

This has THE filters which make THOSE Crumar synth sounds which are behind many of the great hits of the 80’s and 90’s. All the keys and knobs are functional. this is not modified, it is fully stock like it came from the factory.

The unit has some scratches and the veneer is peeling on the end caps a bit, otherwise it is very clean (and could benefit from some more cleaning). The original carrying bag is included but will need some work on the zippers the get it to close fully.” Click here to visit listing on eBay

Crumar Bit 99 Project Machine

“CRUMAR BIT 99 SYNTHESIZER FOR REFURBISHMENT!. Condition is Used. Dispatched with Royal Mail 2nd Class.

sounds great, has one white key that needs attention, it is raised up like a pointing finger. unfortunately it will hold a note if pressed, the key to the left also feels a bit suspect . Just needs a little love .

as stated its for refurbishment and i am sure this can be done with the greater of ease to those in the know..

original patches no longer on the memory chip but this can be dowloaded and reinstalled if i am not mistaken.

Has dated flight case with no key for the lock but serves well to protect it on a day to day basis

im not looking for you thoughts on the synth model, i’m just looking to sell.”

Crumar Performer

“Crumar Performer String Synthesizer – Synth – Made In Italy. Overall in good condition. The only thing I can tell is that some slide buttons are missing and a few shafts may be cracked/broken. I would expect that it works, but I do not have a power cord for it, so unfortunately, I don’t have a way to plug it in and test. I watched a few videos online of what these things can do and what Crumar is known for, pretty neat!!” Click here to visit listing on eBay

Crumar Stratus

“This Rare Crumar Stratus is in Very Good overall condition especially for its age. Everything appears and seems to be fully working and functional although I was not able to test everything there does not seem to be any major issues. The only noted flaws I came across are 5 Dials that will need to be repaired which should be a fairly easy fix” Click here to visit listing on eBay

Crumar Bit 99

“Crumar Bit 99 Analogue synthesizer – Needs repair.

It works but has some problems.
Mainly needs to get up to temperature before resonance kicks in on filters – suspect a cracked pub track or wire
Also some note rotation oddity, some notes don’t play. but this is not a keyboard/ keybed problem. Its completely random.

All 6 CEM 3328s are good and work. So could be used as donor.

Probably needs a re cap and check all pcb traces to make working fully again,

These are awesome sounding synths, give oberheims and JP6s a run for money.
Sonically kick Junos out of the park.
Once I got this many years ago I sold my Juno as better richer sounding and much more versatile.
Has Midi, and there are midi SYSex editors for it. However the keypad entry is pretty quick once you get used to it. ”

Crumar DS-2

“Very rare vintage Crumar DS-2 analog/digital synth. In good cosmetic shape – all knobs and sliders are there and front panel looks good. Has some tape residue on the back. Does not have the lid.

**Has some major functional problems** – it will need work: Only one of the VCOs seems to work and the poly section is not outputing, many of the sliders and pots are scratchy, the VCF and filters seem to work correctly, all keys seem to work, the bender bar is hard to move, and the Pitch poly pot is a little warped. Still makes some cool weird sounds, but definitely not in normal working order.

” CRUMAR TRILOGY,polyphonic analog synt!
CEM and SSM vintage chips.
Nice condition for its age.
Sounds strong analog.
Few scratches on woodsides and front panel.
Crumar Trilogy is very collectable,the prices go to 900-1200 USD,check on internet.

This synt is not in mint condition and need some tunning and fixation to work perfect,so I set the price lower.

I checked this synt ,and will describe the issues I found on this synt
NEED SOME FIXATION,SERVICE!
1.There are preset cards inside the synts,but the preset button on the front panel stuck on preset number 6,(see picture)it doesnt move when other presets are pushed.
2.Ocilators 1 and Oscilators 2 ,VCF filter,LFO ,drawbars and pots works,few pots dont affect the sound when rotated,maybe it is lack of my understand of this keyboard or circuits isssue.
3.The envelope doesnt work althrough I found it is not dead.When I disconnect the connector on the board inside ( see picture)then the envelope start to react but the VCF filter doesnt work.Or vice versa.
3.The synt output connector on the back panel is dump ,but it works fine.
4.Jostick plastick missing,oscilator sync button accept after few pushes, and envelope release potenciometer cap missing,but it can be move up down

Generally,the synt works and produce nice analog sound but there is some circuits mess or connection issues beetween oscilattors, VCF and envelope.Need proffesional touch.” Click here to visit listing on eBay

Crumar Bit One

bitone “This bid is for a Crumar BIT One Synthesizer/keyboard in good working condition.

Comes with a hard case, lead and copy of manual.

There is a small chip on the underside of the last key on the right of keyboard ,but this does not affect the playing or feel of the synth .I Have taken a picture of this also.

The hard case is well worn but still functional, it has protected this synth well over the years.

it was used in a band when bought as new back in the day, by my friends son who used it and after a few years the band split and this synth was put into storage where it stayed until a few years ago when it was found and given to me to play with, which i have briefly but i am not really a synth player but do play piano, i havent got time to learn how to play this properly so i want it to goto someone who can better appreciate and get the best out of it cos its got a great sound and there probably arent many left in the world anymore.” Click here to visit listing on eBay

Crumar Unique DBE Project Machine

dbe “This is the Crumar Unique DBE synthesizer from Italy. It has the most 3 dimensional fat sounds I’ve heard in a synth short of an OBXa. When I got it 2 voices were out. I’ve recapped the power supply, replaced the memory battery and replaced all the filter ics. Now all the voices are working but one is less expressive as the others. I suspect the one of the filter chip holders might need to be cleaned but I haven’t investigated it any further accept that it’s more noticeable when playing some voices than others. I think it is quite useable in the shape I am sending it, however, this is being sold as is, for parts or repair, to be clear.” Click here to visit listing on eBay

Crumar Stratus Project Machine

stratis “Here’s the first of two (yes two!) Crumar Stratus Polysynths that are being sold as spares or repairs units. The unit had been working apparently and then after a period of no use no longer functioned. It has had it’s CEM chips removed from the voice cards I’m afraid, though these do not contain the oscillators. This is a divider oscillator synth and so shares the waveform generation with the organ section. Check out any of the online demos of these if you need to know more of what these machines are about.
The wooden endcheeks are showing signs of considerable wear and some of the graphics are a bit thin on a few functions.
Would suit someone looking for a keybed, some donor parts or a project maybe” Click here to visit listing on eBay

Crumar Bit One

bit_one “Im not going to go thru the specs. The Crumar Bit One is a bit of a rarity and oddity. So, if you are still reading – you know what it is. There are none currently on eBay in the UK.

Its capable of some weird and wonderful sounds when programmed. Thunderous basses and wonderous effects abound. It is fairly unique in that certain parameters (not just amplitude and filter) can be affected by key velocity. The presence of a second LFO is also interesting.

It is in very good shape considering its age. I have had it a relatively short while but am looking to buy an Alesis Ion or Korg Z1 with the proceeds. I would consider a direct swap for said synths.

It has a few minor issues:

1. A couple of keys only play when hit hard or wriggled. Obviously a contact issue and I have confirmed this by using an external MIDI keyboard.

2. There is some very light scratching to the fascia on the right hand side.

3. Three of the keys look to have either burns or melting. Again – they are fully playable – its a cosmetic thing.

Everything else is working fine – LEDs bright, sliders clean and audio output good. Both pitch and mod wheels are working. Note to buyer – you MUST use both upper and lower outputs on the rear. The weird architecture means that the 6 voices are shared across the two outputs.

I shall be sorry to see it go, regret it in 5 years time and be looking for one on ebay again. Such is the life of a synth head.” Click here to visit listing on eBay
