Prophet 6 : 100% analogue heaven.

Great for leads, pads, percussive sounds (even bass drum), bass lines. You can play Bach or Debussy, or Jazz, it will add a certain vibe for you playing. Very versatile synth from the legendairy Dave Smith. You can't go wrong with it. HIGH PASS filter: I would like to point out a unique feature only possible in P6. Make a slow attack, slow decay filter amp, no velocity, you get an organ or accordeon-like sound. Then make LOW pass filter POSITIVE env mod, and HIGH pass filter NEGATIVE env mod. Resulting sound opens up gradually in both direction: a true miracle. I use this for slow Bach fugues. My other favourite feature are the SPRING reverb, apply to any short attack short decay plucky sound. I like it and use on stage, even though I have a pair of real spring reverb.
