My new (used ) Alesis Ion Virtual Analog synthesizer. A very underrated and flexible machine that earns high marks from people who love their true analog sounds.
This is the first synth I buy that isn't sold in a toy store, and will likely be the only one for a while so it had to maximize value for money.
I love all the knobs and how you don't have to really dive into menus until well into the patch. I'm just learning how to tap its abilities but the interface is very intuitive, even the modulation matrix made sense right away.
The hard part is learning how to make good programs from scratch, which is also the fun part. :) I'm just glad I won't be fighting the tool.
