the onboard synths are nothing special. they do the job, its a basic 2 OSC subtractive setup, and the sampler can do about ~2 sounds per key (streams from SD though, so no weirdly low limit.)
@icedquinn@blob.cat can you link a video that has representative sounds of that device? I'm listening to one of their playlists but i am unsure what sounds are deluge "patches" and which are external.
@genewitch best to think of its onboard stuff as sketching gear. it *can* do a decent job, but the thing also plugs in to a studio fine if you decide you want to redo your song with something else.
