Ah, that's great news! I won't be in your way.
The more steps the merrier for my part ;-)
A multi-channel one for starters, designed with the 'run away ideas' in mind, it will be than!
You have my full support.
Keep up the good work you two wizards ;-)

Nina and I are still working out what would be the best interface for it (digitally controlled tempo, pattern length, pattern selection and copying/pasting/transposing/rotating, and entering notes, rests, slides and accents). I don't like the idea of scrolling or layers of menus, so it'll either be buttons and LEDs and potentially up to hundreds of steps, or buttons and a single big LCD and up to 16 steps, all visible on-screen at once.

I'm hoping to eventually work my way up to a fully fledged multi-channel step sequencer with a few different channels of pitched notation, drums and tempo synced LFOs... but I tend to run away with ideas quite a bit!
