OSCar is now regarded as a classic in the synthesizer world. OSCar is a highly-versatile vintage workhorse, suited to many musical genres, but more recently has found particular use in Dance, House, and Electronica. It is an analogue-sound digitally-controlled synth using the classic subtractive but also additive synthesis models to produce its sounds. The OSCar is also a performer's synth, direct and immediate access to its sounds makes playing an intuitive dream

If you've lusted after a vintage MiniMoog synth - don't bother! The OSCar has absolutely stable oscillator tuning, massive programmable dual-oscillator sound with separate modulation LFO, and has been built to take on the road if needed.

This OSCar is 240V 50Hz (but can be internally set to 110V) and doesn't require a separate power supply. The rechargeable internal memory battery may need to be replaced soon (but currently is working OK).

*Operating manual - the cover has come loose from the pages through age (but this is an easy fix), my name is stamped in small font on the front cover, and there is some highlighter on some of the text. Also, my name is written in ink in small discrete font on the OSCar's lacquered wooden base (this can be easily sanded off by the new owner).

**Factory presets - currently not stored in memory. I have put around ten of my own sounds into memory and the rest have been left 'blank'. You can load the factory sounds in if you want to, but I recommend that you make your own sounds and store them in memory, it's very easy to do.

Note that if sounds are 'lost' from memory (through memory battery failure), it is possible on power-up (depending on the random position of the control knobs) to have no apparent sound, or at least a 'nonsense' sound, on key-press. This is not a fault and is resolved by setting the control knobs to appropriate positions and saving patches, or loading-in a set of patches - check the manual for details.

Vintage Arp 2600 Synth synthesizer

via this auction
"Vintage mid 70's Arp 2600 in great shape. Although cosmetically average this particular Arp 2600 is a beast; has had a complete overhaul by Phil Cirocco of CMS. Has the added modules: filter and extra oscillator(more details on Phil's website), power supply upgrade, envelope mods, osc sync(this was done prior to Phil's work but was inspected /serviced by him), audio path upgrade etc etc. I have spent over 3K in rehab and upgrades and this Arp as Phil told me "rocks". I agree and I hate to let it go but this economy is...Phil worked on this arp less than 2 years ago and is functioning as it should but with any vintage synth general maintenance is necessary every year or two so it is likely due to have a good internal cleaning/calibration. The 3620 keyboard's electronics were serviced by Phil while the bushings were replaced less than three months ago by EARS in NYC so this keyboard is good to go."
