it should be noted that if the polyphony of 64 notes do not correspond to current standards (128 notes), this polyphony is very respectable in view of the date of this machine.
Use of this expander is relatively simple in principle for who knows how to handle this kind of machine (oscillators, pitch, filter, envelopes, LFOs ...). However, when we do not have editing software, since there is very little front-panel controls, that is to say 9 buttons and a scroll wheel, editing, yet once simple in principle, can be quite long and arduous.
I do not even talk the way combination that allows stacking multiple layers of sounds, for except to take the sounds existing in the wave table, it should first edit the sounds one by one, which is already quite long, and then edit the combination as such, that is to say basically choose the sounds to be stacked, and their output level.
In summary, editing simple in principle, but perhaps a bit painful in its implementation.
It is quite difficult to give an opinion on the sounds. Overall I would say that the sounds of this machine are quite suitable in a mix, since the sounds are not intended to include "first". However, the use of sound in solo or "first" is much more difficult. Indeed, the sound quality of this machine is relatively far from the current standards, even if overall quality is not bad, far away, to an expander 90s, some sounds out of the same batch.
I think the filter is not very pleasant, nor very effective. The resonance is almost zero, it would indeed have been preferable not to put any resonance to avoid ridicule. The slope of the filter on it seems relatively low and not adjustable (6 db / octave, 12 dB / Oct?), Only a low-pass filter is available.
<div> In fact, the case sounds, the expander can leave things very interesting after a few hours editing and giving himself a little trouble, and use the combination mode by stacking multiple sounds (excellent pads), but such use is quickly consuming polyphony. </div>
I own this expander for about 10 years, bought used. In fact, I bought this machine to increase the polyphony of my set, and in order to have a good general-expander, able to produce extra sounds correct. He made me so many services.
For this purpose, the quality / price of the machine is very good (it was also when it was new ...)
Now if you want a machine with big sounds good solo, a real synthesizer rack, I think it is better to turn to newer machines, even occasionally (and even if they are more expensive) a Triton or Motif (Fantom to not be jealous ...) rack always sound better with editing capabilities much more interesting and important.
