Roland MRS-2 ProMars 70's/80's Vintage Monophonic Analogue Synthesiser - 100V

The ProMars was unique largely in part due to its introduction of microprocessor control, hence the term, "Compuphonic." It used an Intel 8048 processor to control the all-analog VCOs, VCAs, and VCFs. This also allowed it to store patches, making it one of the early few analog synthesisers that had patch memory. 

The ProMars CompuPhonic has 10 preset sounds and 10 user programmable patches. The preset sounds include Bass, String, Clavi, Piano, Voice, Trombone, Sax, Trumpet, Synth I and Synth II. A very standard and well laid out set of knobs, sliders and edit controls give you the power to create some really cool sounds.

Designed as a partner to the polyphonic Jupiter-4, the ProMars is often considered a monophonic version of the Jupiter 4. However, whereas the Jupiter 4 had only one oscillator per voice, the ProMars features two oscillators (that can be de-tuned). Also found onboard are a nice VCF (filter) with its own ADSR, a typical VCA envelope section, a nice LFO and a pitch/mod wheel that can effect the LFO, VCF or VCA. It even has a noise generator. Nice wood end caps add to its vintage appeal as well. (Vintage Synth Explorer)

The ProMars has been used by Aphex Twin, Vanglis, Venetian Snares, Isao Tomita & More!

Fabric is wonderful - and so's everything else!
Size: Medium, Color: White
First off - amazing fabric. It's really flexible and - well, expands as needed - with a really great feel to it. Light fabric, which is just perfect; I'm the conductor of a symphony orchestra, and often like to wear this in white or black with a mandarin-collar jacket. Look is great, comfort is terrific. The sizing is spot-on and I hesitate to say that the price is ALSO excellent...just in case they see my review and conclude that they're charging too little for a really great shirt! Currently, I've purchased two each in white and black for professional use, but will probably get a few more in other colors for casual wear. A-OK!

The Look I Wanted.
Size: Medium, Color: White
I wear mandarin band collar shirts for semi-formal and/or holiday ballroom dances. This shirt was noted as a blend of 63% cotton, 35% poly and 3% spandex. The shirt is shiny and does not have the cotton feel. It is also so sheer that it shows my V-neck undershirt. It seems more of a women's blouse than man's shirt. The neck and sleeve lengths are good, but the body (Medium) is snug since what I rec'd (but did not want) is 'slim'. The seller's description stated the shirts are 'regular cut', but the package for this shirt said 'slim'. Disappointed in that I think the regular cut Medium would be a good fit. I have purchased this style shirt from several Amazon sellers, and all of them have different size issues, ie too tight, too large, long sleeves, etc, etc. I've returned ALL of them, but I have not decided to keep or return this one. The size charts shown on the sellers' webpage(s) are meaningless, so it becomes a situation of 'buy, try and then return'. I think that is why the webpages call out that these are items that are frequently returned!

Quality at your finger tips
Size: Medium, Color: Burgundy
Excellent choice... Price was "on point", material feels good and durable, size fit great, and most of all the colours were great. Actually purchased several. It's nice to receive a product as it is stated and I did. Recommend very much. Oh and, can be worn at various times of the year. Wash and hung to dry is recommended to preserve quality.
