CRUMAR CORDATRON (1974) Castelfidardo

This is an accordion string machine with organ section, a brass synth section with filter controls, trigger-able analog drum sounds and chord and piano presets on a Stradella button board.
Crumar made a few different models of this type of instrument but this is the very first.
Unicorn rarity is the order of the day regarding the control key- and button board - the serial number 3 of allegedly 10 units ever put in production.

Crumar had just started producing keyboards after mainly producing accordions, and around this time they launched the three COMPAC models that definitely inspired the sections of the Cordatron: Compac Strings, Compac Brass and Compac Piano.

Most of the CRUMAR CORDATRON specifications are in the video as text already so please watch the video and read the text - but a quick roundup would look like this :

The instrument consists of mainly two separate units connected by a huge, hardwired 3-piece connector : the main sound generator unit with power supply, audio outputs, tuning and volume pedal, as well as the control unit - basically a butterflied accordion with a Stradella button board for the left hand and a regular keyboard for the right hand.

All the sounds are analog and are generated by the very first generation of divide down technology - no eproms or other intruders of vulgar modernity is on hand.
The sound generator weighs 23 kilos and is literally crammed with sandwiched layers of massive circuit boards of transistors and capacitors.
