I also did the same with a Yamaha EZ-30 I think is the model, it’s a really nice plastic keyboard, has like 670 voices. And now I’ve tried using an Altura with a Behringer TD-3, and learned that you don’t have to use the sequencer functions, you can just use the nice midi controlled synth, which has a lot of cool voices. And this evening I’ve been playing a Yamaha PSS-795, a really old model that really works well with the Altura and has a lot of neat features. I’m making some mad sounds over here.
