The Aira range is fairly affordable and beginner friendly. The S-1 is no exception, but there is a lot more to it than may seem at first glance. This is a very capable, highly-customisable 'analog-like' synth. I've been using it for several months, and I can't think of any flaws, it's that good! If you are looking for a particular sound, you can also just plug it into a multieffect pedal. In short, if you need a classic analog-era synth, start here!
