First synth purchased for my 80's cover band project.

Great sounding virtual analog portable with full size keys. I love how much power it has but programming is a pain. I love the horizontal pitch wheel but the mod sliders are crap and the buttons are too small and over time can stick requiring lots of pressure to make them work. Most Microns have output problems and mine is included. Luckily it's only the right out so I don't have to fix it right away. Also my headphone jack has a high pitch hum and should be replaced. I got this for $175 on ebay.

Like this guy

I got this while on tour and our other rig broke down. Sturdy as HELL. Survived several US tours and a particularly drunken European tour. Tho I can now clearly say I have definitely not been exploiting all the great lil' noise makers I've got. I have yet to really dive into this as I essentially just needed something that could to the 3-4 sounds we needed for our sets.

Maybe my favorite thing about this website- I drag every thing back out and revisit it. This was under a end table. Da fuck?

Anyone with clever isights on this guy please drop a comment. I'll be putting this guy thru the paces now.

A great first synth!

This was my first keyboard synth and has been very reliable and durable over the years. On top of that it has a strong user base and decent vst editors making it a great synth to build new sounds with. the latch memory looper function is awesome when making your own arpegios and not needing to be frustrated with quantizing.
