Actually, I think this might be a stronger end-result:
Notice that it retains a proper touchplate controller now, with a LOT of functions that were missing (like sequencing). Plus, this is a beefier controller than the usual LEM 218. Then for the open slot that left, I put in a 257e which gives you some CV processing as well as a trio of slope generators that can act as a more complex modulation source. This seems to me to be a lot more solid, especially if you were to add Northern Light's O&c card for the cardslot.
