Selected MIDI Accordions

New 37 and 38 keys accordions - light weight, compact size, hand-made reeds


The Super Quattro Artist was inspired by some legendary accordions like the 1960's Scandalli Super VI and the 1980's Guerrini President as well as 60 years of combined experience of Ivan Stanojlovic at Siwa & Figli and Guenadiy Lazarov at Accordion Gallery.

The 6-row B-system chromatic model sets the quality standard for the new chromatic Balkan accordions made today. If you play this type of instrument we invite you to the Accordion Gallery to try one of these special accordions. Chances are you will bring it home with you.

Ron Oswanski is a recognized talented musician, performing wide range of repertoire spanning from jazz (Hammond B3 organ and piano) to polka and fusion (accordion). He has been an Accordion Gallery friend and customer for years. Recently I had the pleasure to work with Ron and Siwa & Figli on the design of a custom-made  accordion suitable for all different polka styles from Slovenian to Cleveland. The challenge was to select the right reed configuration and tuning while keeping the instrument compact and ergonomic. 

In Ron's words "The Siwa Schumann custom made for me with the help of Guenadiy and the Accordion Gallery captures everything I was looking for in a musette instrument.  The accordion is custom designed from the ground up with a reed configuration of MMMM.  The appearance, tuning, size, and midi capabilities are as good, if not better than anyone can expect out of a high end accordion in a compact design.  The custom musette tuning was exactly as I asked, and Guenadiy was more than happy to help map out for me.  The Schumann, on top of it being a power house instrument, has the bonus of wireless midi built in.  The setup allows me to not only run built in sounds from the internal sound card, but gives me the ability to WIRELESSLY run Mainstage at virtually no latency.  With a series of volume pedals, I'm able to mix my acoustic accordion with not only multiple bass setups, but combine those options with various synths all in real time and again,...   all wirelessly!

Thank you Siwa and Guenadiy!!
