 In details 

patch selection

VOICE classic full analog synthesizer based on master oscillator S10430 with octave divide down AY-3-214.  
The RS-09 is mainly based on 2 layerable sounds:  strings
& organs.

The sounds have 4 common sound controls:

1. Transpose

lowers both section to 1 octave range.

2. Tone filter adjust

A simple filter emphasis cutoff. Just a knob, no resonace. More like a little EQ.

3. Vibrato LFO

A volume modulation with variable frequency, depth and delay start.

4. Envelope 

A shared control for the release with 2 retrigger modes.

Organ Section

Feeling like Bach? well this section sounds absolutely not like a church organ... not even a B3... Very retro sound, the Organ section feature some individual tonal controls:

Octave mixer

Organ have different octave feet that can be mixed: 8' 4' 2' 1'

Organ I -II / Tone

2 different kind of organs.
Organ I-II (later version)
Tone I-II (early version)
First one  is more bright.


Turns on/off the chorus effect.

Organ Tab

Only on early version! a kind of mono mode, sound goes out from the dedicated out.

Our Verdict 

"Very lush retro sound, like it! not really a professiona Roland RS or VP, but you can achieve some good sounds out of it (if you like string-like stuff). These are getting everyday more expensive. " 





Quality / 



- limited
- getting expensive
- some rare IC (like early reticon)


- lush sound 
- vintage strings
