As someone who has purchased a MKII Pro, I have a few tips.
I love this kit. It's fun to play, the module isn't bad out of the box, and the playability is great. Getting a kit this size at this price point (~$1200-ish) is a pretty good value. This is my first e-drum kit (after being an acoustic player off and on for 30+ years), and first Alesis product since I bought a midi sequencer way back in the late '80s. It does what I thought it would, and exceeded my expectations as to the sounds, responsiveness and possible expandability.
That's the good news. The bad news is that the build quality of the mesh pads is awful. Well, the wiring is awful. tiny filament wires with brittle insulation that readily breaks under normal usage. Perhaps I've been particularly unlucky, but after going through two kits, I feel they missed out on some quality controls. The first kit to arrive worked perfectly for about a month and a half. Then the snare trigger started to fail. Eventually only the rim trigger was working. So I cycled through the other 12" toms, using them as snares, until I had "broken" all the 12" pads. They all failed in the same way, ostensibly from the same cause.
The way they failed is the wiring either breaks (the wires are brittle), or the solder/glue connection fails. The cause of the failure seems to be hitting the pads with a stick (I assume that's something of a product feature with drums). So due to my purchase through Amazon Prime, I received a whole new kit, as well as two auxiliary 12" pads (a nice touch) and returned the old unit. This was a hassle, as I had to rebox everything and take it to UPS. But it was all free, so at least that wasn't an issue.
Fast forward to last week. Another pad failure, and yes, it was the snare. I am NOT a basher! I don't hit these things with baseball bats. Since I knew where to look for the point of failure, I took off the head and there it was, a broken red lead. So far, this is the recurrent weak link in this kit. Either one or both of the wires leading to the main center trigger break. Since I received two extra pads, I figured I would try to fix the malfunctioning one with a more robust setup. I ordered some new transducers (triggers) from Goedrum to replace the factory-installed ones, and this is where I find myself right now. I might try to upgrade the wiring alone with a more sturdy gauge and keep the Alesis triggers, but I haven't decided that yet.
Now, despite my displeasure with Alesis and their build quality, I did decide to keep the kit. I couldn't justify returning it again and "upgrading" it to a Strike or some other manufacturer. Cost, wasted resources and no guarantee that I wouldn't end up with another problem has resulted in a DIY mindset, and I will learn everything I can about using the base kit as a template and "pimping" it out to my liking.
If I find I'm not happy with the way that's working out, I plan on moving on to Laurin pads and integrating them into my kit as I move forward.
I'm happily adding a VST to the mix, bypassing the module sounds altogether. I think I've decided on Addictive Drummer 2, though EZ Drummer was pretty cool too. It lacked a few functions that I feel are useful, and I couldn't fleet up to the Superior Drummer from Toontrack at this time. Steven Slate was another option, but they don't have a demo to try out, and the SSD5 is coming out soon, so that might be a purchase down the road. For now, I will be getting to know AD2 and paired with my Behringer UMC404HD, I think I have my latency solved on my Macbook Air.
All in all, the DM10 MKII Pro is a decent kit at a good price point. There are some build quality issues, but they can be fixed if you're willing to learn a bit about your kit, and especially if you are buying one that isn't under warranty. If you know what the issues are going to be ahead of time, you can plan for them and get an even better deal. While I don't think selling a brand new product with what seems to be a perennial manufacturing error is a good business model, the work around isn't terribly complicated, and for the price, it's likely worthwhile.
Happy drumming!
