Yes, keyboards: piano, organ, synthesizers, samplers, etc.

I enjoy mimicking other instruments (especially guitars and solo wind instruments) on synths, using technique (!), programming and layering, and controllers (wheels and joysticks, switch and swivel pedals, touch pads, the keyboard's velocity and pressure sensitivity, etc.), to bend pitch, vary modulation depth and rate, vary amplitude, frequency, or filter parameters, and crossfade between different patches etc., etc. It's interesting what you can do, and how good it can sound--but it's never as good as the real thing. Quite fun though.
