A bit of background on my experience with E-drums
Back around 1994 I was asked to build a system that would facilitate a 5-piece cover band traveling in a C21:
There is not enough room in this plane for a decent acoustic drum set. Some sort of nesting kit might work. But IME serious drummers tend to hate nesting kits as well.
The drummer in the band at the time proposed some sort of suit that you wore that had pads you played with your hands. He also proposed something like this:
My impression is he made what I considered "unserious" suggestions in order to increase the chances that he would be able to play his regular drums most of time.
I rejected these idea as I thought it was important to have something that any drummer could understand and play more like real drums, even if they hated it.
The solution I chose:
A big part of my decision was due to how quickly the TrapKat can be set up and how compact it was when packed.
The original drummer wanted to send me a single stereo mix and control everything through the user interfaces of the TrapKat and Roland TD-7 sound module. The first tour did not go well because the drums sounded awful and were out of balance. I did what I could to help him make the adjustments, but everyone in the band was complaining, including the drummer. Eventually I told the drummer to STFU because it went exactly as I predicted and it could have been avoided if he would have allowed me to break the sounds out in a sensible way from the beginning.
When we got back I rewired the system to break the individual instruments out as much as possible. We still used one stereo mix because the mixer only had 16 channels. I think I had cymbals panned across the stereo mix. Bass drum, high hat, snare, and the toms had dedicated channels on the mixer. This set up worked way better, especially after I helped the drummer dial in some of the MIDI parameters so the sounds responded more intuitively.
After that, the original drummer made do and tolerated the TrapKat. However I suspect it may have been a factor in why he left the group. In particular one of the things he repeatedly brought up was the potential for repetitive stress injury from playing on pads. I acknowledged his concern and suggested that he use a light touch.
The second drummer loved the TrapKat and had a lot of fun with it. I had to teach him a bit about MIDI and how to access and adjust various menus. One of the things he really liked was that setup and tear down only took about 5 minutes. When he played real drums we frequently had to wait for him to finish tearing down, because he would wind up talking to audience members.
Audiences loved the TrapKat. They thought it sounded good and were curious about it. We had many top-brass military officials and high-level dignitaries from different nations come up after shows to discuss. We frequently invited them sit down and play around on the TrapKat a bit, and they had a blast. I don't ever remember DVs showing that sort of interest in real drums, but they seemed irresistibly drawn to the novelty of the TrapKat.
Problems:
The TrapKat did not do well outdoors in direct sunlight. The pad surfaces would get noticeably loose and cause problems with triggering.
On occasion part of the system would lock up and need the firmware to be reset, meaning all of the presets and MIDI parameters had to be dialed back in. This led to some stressful moments but never delayed the start any shows.
As mentioned previously, some audience members said we sounded too much like a CD.
