What you need is a Synthstrom Deluge, it doesn’t have any limit on the number of steps and bpm up to 26624.
I get out my Tracker and Play when I see something new to try but my Deluge always goes back on the desk after a day or so because it’s so versatile and can achieve all that the other instruments can do and more.
I can transfer the resultant sounds from the Deluge onto the Tracker or Play once I have ironed out any wrinkles.
