Vanguard from reFX is a VSTi for your DAW that reminds many people to the favourite VSTi Sylenth1 from Lennard Digital. The downside of Vanguard is that it is a 32bit only application. So, if your DAW is 64bit only, the VST instrument will not load.
There are a couple of solutions out there and the solution we have chosen is the usage of a tool called jBridge. You can find out details here.
Vanguard can be purchased from the reFX website and is for download only. Seems reFX have removed Vanguard from their product range. I actually asked for a demo version first to see I can hook it up with jBridge and make it work. It worked like charm and somehow feels even better integrated to eg Logic Pro than Nexus2 does. The plugin will set you back some 80 USD, pretty heavy if you consider its 32bit only. However, registered owners will have access to a planned 64bit version upon release.
Upon installation of Vanguard your DAW will automatically recognise the new plugin (32bit DAW only) or in case you require a middleware like jBridge you may have to confirm manually the load of an “invalid” plugin or even manually guide your DAW to the “right” plugin to have it working.
Vanguard will present itself like this upon selection as an instrument from your DAW:
