"The phillip rees gives you provision to control two CV controlled synths at the same time (not independently). Extensive gate tailoring including s-triggering, Velocity and pitchbend range. The SH101 has a jack socket on the back for modulation of the filter using velocity messages from a sequencer, this enables filter control from your sequence. This is a mod i have added myself and adds a new dimention when sequencing."
