I like the Monologue because of its sequencer and the one-knob-per function. I don’t like that it is so aggressive-sounding. But I still own it regardless (for now at least).
Every time I go to the music store, I play the Minilogue. I love the sound of it. I also like the voice depth modes and that it has an arp and delay. Of course it’s polyphonic too. It just feels more musical to me than the Monologue, unless I want to go off into glitch/dark/IDM-ish mode, then the Monologue is great for that.
But that Minilogue motion sequencer is a turn-off in comparison. From what I can tell, you can’t manipulate the motion sequencing in real time like you can with the Monologue. So you can’t turn on/off the motion sequencer steps individually or p-lock the steps. Also you can’t transpose the sequencer in the Minilogue like you can with the Monologue via the key trigger mode.
Honestly, I get sounds/rhythms out of the Monologue that I haven’t gotten out of other synths. I just have to decide if I like those sounds enough for the table space it takes up. I’m not sure I do anymore. It is a lot of synth for the money though.
