Yes, you can pick up a kenton pro solo and will be able to send midi note on and note off information to the 202.
Note that the 202 will also hiccup, as previously stated. The CV/Gate Ins on the back are made for inputting data into the sequencer via a CV/Gate keyboard, not for fast live playing. The microprocessor will quantize everything - ie slides will move in semitone increments.
If you wanted to sequence via midi and cv/gate, and not have to worry about note hiccuping and quantizing, you have to modify the board by cutting two traces, and wiring in switchjacks.

Vintage sound comes with a price.
and really, half the fun and funk comes from that sequencer. Input 8 notes, set all notes to 16ths, add a couple slides and accents, set the accent to control the vca and vcf, and turn on looping

== better 303


Read the manual on it, it's not hard to grasp really.
