This simple little plug in can really be a workhorse if you allow it. when I'm just starting a track I will usually start with this. It's just so easy to work with. The sound can be very limiting so you have to know when and where to use it. It's good for basses and leads of course, but use it with effects or layer it with a more substanicial vst and there is when you see it's value. The filter, as with all Muon products is very nice. The sound really cuts through in the mix, which is why it's good for layering. It's very stable and the cpu usage is the lowest I've seen. Like I said, it's always in my rack.Read Review
You can still get this classic freeware plugin dating back to 1999 over at Wayback Machine. The main difference between the 'Pro' version and this one, is that the Pro has 12 note polyphony and supports pitch bend and mod wheel. The free version has 8 note polyphony and does not support those MIDI features.
Not a bad synth, but super limited. No pitch bend or LFO means something like vibrato wouldn't be possible, nor pitch slides. But it's oscillators and filter are way better than on Neon for example. And all parameters are open to automation. Good for old school sounds.
