Just a general tip for those using the Eigenharp with Reason.
I find that I get better performance from the Reason instruments if I raise the overall decimation level (in EIgenD -> MIDI Router setup) to 50 instead of the default 10.
At 10, EIgenD sends more data than Reason can handle and this results in some random note cutoffs. At 50, this sends enough data to properly affect modulation and pitch bend to control the synths well.
Hope this helps.
