Step sequencer plugin like the one in retrologue

Does anyone know about a Good step sequencer plugin like the one in retrologue 2?

If you have an issue of computer music magazine 234 or newer they have a good step sequencer free, the only difference between that and the full version is you can only run a single instance in a project, it only costs about £30 for the full version anyway.
