Nice one ! I like the synthi acid sounds about 5 min. in.. Can you tell me what filter that is ?
yeah, its just the MFOS WSG filter slightly modified. the complete schematic is on my blog if your interested
What are these things originally and where can i get one, or is it something built from scratch?
its a generic toy keyboard from the 90"s. it came in many models. most notably the "tandy elephant keyboard"
