#1. Sensing times below 1ms while maintaining reliable volumes/impact force.
#2. Impact sensing that goes to 4 times below current thresholds and 4 times more than current thresholds.
#3 Network (RJ45) midi transfer for under 1ms transfer of MIDI to DAW.
#4 Update to the drum/MIDI format to allow for rim and head to have separate levels for use with blended samples (One for head, one for rim)
#5 high hat with controls blending 4 inputs. Start with VH-12, add the KAT FSR strip under the pedal, use a mixture of the two for hat position. FSR trigger with pizio (or better) position for the trigger level.
#6 General update to midi for 4000+ levels vs.128. and 256+ controller signals for aftertouch signals on every sensor/note. up to 8 vel levels/drum. The first three would be head rim bell. Im sure we will come up with uses for the the other 3, especially with a snare once you get side stick/brush involved.
#7 FSR mesh heads
In general, the triggers are the weak link of Edrums.
The problem is to many patents. No one company will be allowed to make anything because Roland will sue the hell out of them. And Roland just milks 30 year old triggers without really upgrading the concept. One good example is Hart. They went away because Roland put them out of business. Roland Tech support is useless or very time consuming to get the response......figure it out your self.
Oh yeah, you want a set of mesh toms of more than three sizes......nevermind DIY.
At least they came out with an 18" cymbal. Should have been 21"
