I have a synth for sale in excellent condition, it is the Alesis Micron. It is actually the exact same synth as the Miniak by Akai but Akai was merged with Alesis and they decided to rerelease the Micron as the Miniak which are both a rerelease of the much larger but older Alesis Ion.
If you are looking for industrial sounds and dark themes, the Micron is pretty good at that because it has pretty decent FM Synthesis features which can be used to produce harsh tones and screaming synth sounds if you know what your doing.
The Miniak/Micron is also a built in step sequencer and drum machine and has an advanced and useful display i found much more visual and helpful than the mininova, also it has normal sized keys and i believe 39 of them.
Contact me for more information, i will give you a good price way below $400. I am selling it because i want to buy an MS2000
