Quick impro and functionnal demo of the underated Roland RS-09 MK2 polyphonic synthesizer. The Roland CR78 is mainly here to gather your attention :-)

Sure it would not be my first choice, and even not my third, when it comes to string synth but the RS-09 has some tricks up it sleeve that makes it worthy of interest. The main one is it's ensemble FX which is a 4 BBD stereo chorus with 2 modes. It's give a very rich sound, especially since it's stereo, and keeping with Roland's tradition of ensemble FX, it sounds quite different than your typical string synth triple chorus.

Next best thing is there is an audio input so you can run your favorite synth through the ensemble FX (and through the filter). Works very well with analog polysynth's pads.

The organ section on its own is not very interesting if you compare it to an actual organ. It lacks the percussive attack and bite of combo organs for instance. But if you consider this section as a way to build harmonic pads it can sound very sweet. And of course you can route it to the ensemble FX which dramatically changes things. Last but not least of its quality is its dimensions and weight !"

via this auction

"Analog polyphonic (paraphonic) poly synth with organ and string sounds.

It has a very nice sounding stereo ensemble fx, based on 4x Panasonic MN3004 BBD chipsets, just like in the VP-330 or the Jupiter 4 (which only has 2 of those). And most importabtly it has an audio input so you can run any source through this great stereo chorus. The audio input even goes through the filter ("tone"). Another very nice feature is its weight and dimensions ! You won't find many strign synth and/or organ you can carry so easily around.

Unit was serviced and is in full working order. The organ "ensemble" switch can be a bit temperemental but nothing major.

Cosmetic it has many scuffs and doesnot look so nice so that's why you can grab it for cheap. "
