For those that don't know... Arpeggiators are THE BOMB! Few things are quicker, more fun, or easy than holding down some keys and having 'instant melodies' come flying out of one's speakers. My first synth had an arpeggiator and it was intoxicatingly good fun! Any time I have a synth without one I often feel it's missing something essential. Change the keys randomly and you get all kinds of cool stuff you'd never play on your own.
There are tons of cool arpeggiators out there - but here's a really nice one in VST form for $12 US called ARPG8R.
ARPG8R - VSTi MIDI Arpeggiator.
I'm considering getting this. I really wish the developers of NanoStudio would add one to their devices - it would make their software indispensable on the go! Most of my hardware synths had them and I practically consider it an essential tool.
What do you think?
