MIDI sequencer?

[Barry L Klein]

I'm curious if anyone is familiar with a the application/design of a
sequencer to send program change commands as well as note commands for
each step to create a Wavestation-like sequence out of a K2000 or whatever
synth?  Is the program change handled by the synth in a fast enough manner
to prevent audible delays?  Does one of these smaller rythm sequencers
allow you to do this?  Software program?  User-friendly enough to just
turn a (virtual?) dial and scan through the synth's program sounds?
