I was really excited to hear about this.
First lets look at the positives...
1: Someone other than DSI is making a well built, true analogue synth with VCO's and bags of polyphony for under £2000!
2: it has 3 oscillators including one that can be user assigned.
3: It's bi-timbral
4: Voices can be layered and split, effectively giving you a 6 oscillators to craft a sound...nice.
5:Two displays (LED & OLED) for navigating the synth.
6: Analogue compressor on the 16 voice model
7: Two effects (1 mod effect, 1 delay/reverb) per voice
8: It's built using aluminium & oak and looks the business!
So far so good - but now for the negatives...
1: To get 16 voices you must buy the 5 octave synth - there's no way to upgrade an 8 voice model to 16 voices like there is with the REV2.
2: No aftertouch on the keyboard!!!! I mean ffs - really? That's an unforgivable omission on a supposedly 'flagship' analogue synth IMO.
3: Only 1 LFO. If I could change anything about my beloved Prophet 12 & Rev2 it'd be to have more LFO's and they already have 4, so offering only one LFO feels like a serious limitation to me - even my Studiologic Sledge has 2!
4: Despite being bi-timbral the Prologue has only a single stereo output, it does not have separate stereo outputs for each sound like the Rev2 & Prophet 12 do.
5: Voice spread and compressor only available on the more expensive 16 voice model.
6: Did I mention no aftertouch...I mean seriously...wtf!!!
7: No auxiliary envelopes
It's such a shame that Korg chose to impose needless limitations on the Prologue.
Sure it'll still be a good synth, but with a little more thought it could have been a great one.
Include aftertouch, more LFO's, a couple of aux envelopes and separate stereo outputs for the voices would have made a world of difference IMO
As it is, I'd be thinking I've paid £1700 for this and there's not even any bloody aftertouch!!!
Good to see Korg throwing their hat in the ring though - over to you DSI!
