Roland JUNO-106 by Prahlad
This is a 6 voice analog synth with digital envelopes and built in MIDI interface and chorus section. Every function has a dedicated knob or slider and it even has preset memories!
The Roland Juno 106 was one of the first analog synths I bought and I am so happy I did. IMO it's the perfect synth to learn synthesis on as everything is right in front of you and it's easy to get a wide variety of sounds out of it.
The on board full MIDI interface (all parameters can be recorded, but not edited! Sys ex) and and very useful chorus FX section make it a great all rounder.
Then synth is built solidly and weighs a lot for its size.
Fat funky basses, luscious chords and punchy leads are just a few tweaks away.
Unfortunately used market prices are ridiculous at the moment, but I would say if you can find a unit around the 5 or 600 Euro mark go for it (test the voice chip by playing 6 notes!)
-Very easy to use and learn on
-Possible to record MIDI parameters
-Prices these days are ludicrous
-Envelopes are digital, but still funky enough
-Voice chips are known to break but can be replaced relatively cheaply
-No unison detune
