The V1.50 software features the following compared to V1.40: 1. New Factory kits (F.27-F.99) based on the ddrum4 SE Signature sounds. 2. The output signal level has been raised by 6 dB. 3. The ddrum4 SE module responds to (and sends) MIDI Volume (CC#7). This is global for all kits/sounds. 4. You can Mark entire sound groups for deletion, dumping etc with the Shift-Mark function. 5. You can "disable" the DYN curve to get a non-dynamic sound (75% of maximum level). 6. 9 selectable sound variations for MIDI SDS samples. (the same voice will be retrigged for every new trig signal) LOWER SHIPPING COSTS FOR MULTIPLE PURCHASES When buying more items, do NOT use the eBay checkout, it could calculate the shipping costs too high.
