Not to mention most of the functions have a dedicated control rather than calling up a page for each function. If it comes down to a certain vintage type of sound then this may be a factor in favor of the Xpander.
i totally disagree, the Xpander is massively capable, and allows completely free-running modular style madness without a note-on trigger. and i've always thought it has a brilliant user interface, it is efficient & non-cluttered despite it's huge modular archecture, it is completely logical. 24 years down the road and it doesn't have an aged, faulty contact keyboard attached to it nor does it superimpose a keyboard as a controller.
from an old post:
5 LFOs per voice, waveforms for each are selectable from:
Triangle, Square, Up Saw, Down Saw, Random, Noise, or you can have it sample ANY modulation source at a user-defined rate for the LFO shape, which is unreal modulation possibilities. all waves- including the Sampled waveshape- are lag-process-able by their own dedicated lag processor or one of the general modulation lags. all LFOs can be freerun (modular synth style!) or retrigger-able, with a single or multi or external retrigger mode, and you can define where in the wave phase it will retrigger to! you can independently modulate the speed and amplitude of each LFO by any modulator, up to 5 modulators for any given destination. you can use all 5 LFOs (five distinct waveshapes at once) for any given destination. oh, and the vibrato modulator is a 6th LFO, but it is global to all voices
Oberheim Xpander/Matrix-12 has the following modulators available per voice
5 DADSR envelopes
3 five-point tracking generators
4 ramp generators
keyboard (key number as controller data)
velocity (number as controller data)
release velocity (number as controller data)
pressure (any MIDI controller can be assigned to this)
VCO2-VCO1 FM or VCO2-VCF FM
2 pedal inputs (any MIDI controller can be assigned to this)
2 MIDI control "lever" inputs (any MIDI controller can be assigned to this)
also, you can modify the Xpander for 6 external inputs (they disengage & replace the noise source when a cable is connected).
the filters have 15 modes, it is basically capable of infinite sounds, so the idea of it as having a "vintage" sound is strange. like the andromeda it's a powersynth and capable of a massive palette of sound.
... and everything in pea-green on this pic can be modulated by ANY of the modulators:
classic Xpander sound:
