> I use a Roland SH-101 as keyboard and sequencer.

i also heavily use an sh-101 with doepfer. it's my favorite keyboard
controller and great for sequencing basslines and stuff to a clock.
i love the simplicity of playing in patterns and like the fact that
you can't save or edit them - creative limitations.

sometimes i use a csq-100 with my synthesizers.com system, not as fun
and simple as the basic 101 sequencer but it has a few nice tricks

i wish the if the FR mobius allowed you to input notes via midi
keyboard - that would be nice
