Korg Prologue 16 by rotundness
This review will focus on the analogue sections of the synth since the Multi-Engine is still mostly an unknown.
If you want to be able to modulate everything under the sun then grab a DSI Rev 2. I did and I love it. If you want beautiful, alive sounding VCOs that don't need much modulation...The Prologue is your synth.
Menu diving is minimal and intuitive. Fast to edit on within a few hours of use. Sounds like real VCOs because they are. And they sound glorious. Drift for days. It was so refreshing when I first heard these oscillators. Everything else I own seems very/overly controlled to be in perfect tune all the time. (Rev 2, Sub 37, even the OB-6 could be a little less controlled imho) The Prologue definitely isn't and I think we will see more synths behaving like this in the near future. Korg shows some guts here and I applaud them. You also get Crossmod, Ring Modulation and Hard Sync between the analogue oscillators. The arp can be pointed at either layer or both layers.
One thing I keep reading is that the price is too high. Well, VCOs cost more to produce then DCOs. The keybed is very high quality if you can live without aftertouch. The knobs simply work as they should every time and they feel proper. Very precise control over things like oscillator pitch. There is no center detent on the pitch knobs but Korg have managed to make it very easy to zero out the pitch controls. They just magically lock into "0" when you get close. Detuning by 1 cent or 2 or 10 is very easy and precise. If you want even faster more precise control, press shift while adjusting the pitch. This locks the changes down to exact semitones. Super fast to set up perfect intervals with no guess work or listening fatigue.
The filter is a 12db Lowpass affair but this one will self oscillate. Apparently that isn't very easy to do when designing a 12db filter. The cutoff does enough to remove all the high end if desired. This filter has a sound unlike any other synth I own. There is no loss of low end or volume when the resonance is increased. This filter is special in my opinion.
Korg has some issues to resolve here.
At the moment the arpeggiator has no beat division control. It is stuck on 16ths when in external clock mode. Also the gate time only shows up as a mod destination for the mod wheel.
The knobs can be a little slippery but I adapted to this quickly.
No aftertouch but you knew that.
1 LFO per layer but you knew that too.
The Multi-Engine is still an unknown quantity.
There is a lot I haven't mentioned...Voice modes. Duo mode adds a second layer to the sound and can be detuned quite a bit. Your voice count will be reduced by half in this mode. You get 2 octaves of sub oscillators in Mono Mode with a mix control. This can get too big real fast. Too big? Is there such a thing? In this case yes. A little goes a very long way. Chord mode has predesignated chords in memory. All the usual choices are there but you can't assign your own custom chords. Unison Mode is as massive as can be.
The digital fx sound great while offering 10 different types of Reverb, 7 different types of Delay, 8 types of Chorus, 8 types of Flange, 8 types of Phaser, 3 types of Ensemble. The chorus section also includes a handy vibrato setting. Excellent move by Korg there.
Well that's it for now...Until the Mutli-Engine becomes more robust anyway.
