Is the kick made with Synth1??heres the angry side of synth1. dont piss it off
Synth1 is that kind of tool that should be unknown just as some other plugins (doesn't matter if they are freeware o payware), but unfortunately KVR does the job of let it be used by unexperienced hands.
I think that the only problem to reach everyone is that handling banks is not really easy (fxb's doesn't keep the full bank) and it only manages 10 (x128 presets) banks that is a poor offer to people used to work with presets.
But once you know what's going to happen tweaking each control before touch anything presets are only a fast way to the sound you're trying to get, and Synth1 has a clean interface that accelerates the understanding of it's synthesis engine.
Of course, without some free plugins like Synth1, some vstdevelopers wouldn't better benefits, because this synth is the starting point for a lot electronic music creators.
