16 analog filters make a massive difference to the sound of the oscillator section. They are noticeably different than the digital filters (which are very good anyways, if you've never played with a Q you'd be surprised).
In addition to the 16 analog filters, the Q+ gives you 100 voices (the standard Q is 16 voices, or 32 voices with the rare expansion)
Add onto that an arpeggiators and a sequencer per voice.
And wait till you check out the Xphorm function that allows the morphing between two completely different patches, assignable to things like key velocity and the mod wheel.
The Waldorf Q+ is topped off with 8 effects processors (2 per sound that include Chorus, Flanger, Phaser, Overdrive, AM, Delay, Reverb, etc.), oh, and add on a very nifty random function, plus drum mapping for dedicated percussion sounds and you have one of the most powerful synthesizers ever made.
From a physical perspective, there’s 58 knobs (all send/receive MIDI), lovely keyboard and pitch/mod wheels, 2 analog audio inputs, 6 outputs and 1 S/PDIF output (44.1kHz / 48kHz switchable), CV control, and of course Midi In/Out/Thru
The power supply is universal, so wil work anywhere in the world. with no need to worry about step up/down transformers."
