i found the eko super junior a for 5 euros THIS morning. it seems to be HARD to FIND, moreover there are few informations about it on the internet. we get a polyphonic preset synth FROM 1979. wooden and black plastic. black and white, KOLD WAVE BABY !! eko is an italian guitar company, it belongs to the SIEL or crb's sound. analog and COOL. not great but NICE.
there are 4 preset sounds which can be cumulated. for instance, if you put HORN and string, you obtain (in the BASS notes) the synthpunk BASS sound of the BAND the screamers
. there is ALSO a vibraton (on/off ONLY), quite useful. the presets don't sound as instruments, but as electronic noises, GOOD point.
there is ALSO a rhythm section and an accomp. 6 preset. WARM sound. you can easily MAKE one (ONLY one) track WITH it. concerning the accomp., the keyboard is seperated in 2. on the LEFT you HAVE the BASS arpeggio, at the right you MAKE the manual SOLO.
before i forget, there is no LINE out but an inner loud speaker and an headphones LINE. i'll try to add a LINE out by myself WITH a solver. voilą !
