The AN1x can produce impressive and fat sounds because it has two oscillators (both with pulse width modulation), feedback and unisono mode. Furthermore FM, Sync and Ringmodulation are intergrated. With its effects on board you can make it sound pretty expensively. Using its cool 16 Step Sequencer you can compose lines you donīt get in a software sequencer that easy way.
With this package the AN1x is really a good and cheap solution compared to other virtual analog synths eg Roland JP 8000 or Access Virus.
