Many thanks for the hint. First thing I see on the list is ModulAir by Full Bucket Music. I used other synths from him and they are really cool and efficient. So there is already something to check out at the first place of the list.
Modulair was used for a recent KVR One Synth Challenge. Here you compose and make a track in 1 month using the synth of the month. ALL sounds MUST be made with the synth. See here for the tracks for your listening pleasure!
