“The UW Machinedrum models feature a sampling engine. It allows you to incorporate your own samples in the Machinedrum environment and to capture samples in real time. The UW MKII models feature 2.5 MB of sample memory.”
The UserWave version allows you to use samples instead of synthesis for any voice you chose, and to re-sample the internal tracks for some crazy rhythm mangling
The sampling engine is far from being as capable as the Octatrack, but even then, you’ll be capable of producing music with the MD SPS1UW that you can’t do with the MD SPS1 combined with the Octatrack…
I had the exact same choice a week ago (A4 & OT owner, looking for a drum machine by Elektron).
I didn’t want to wait 3+ months before incorporating an Elektron drum machine in my setup.
Eventually went for the SPS1-UW+ last week (right after the AR announcement) and I’m very happy about it.
I don’t think the AR is a superior machine to the MD, btw, just the analog version, 13 years later.
I, for one, will also get the AR when it’s available (and my pockets are full again ).
But for sure, the MD SPS1 (UW or not) is a very nice drum synth !
I think most of the price difference between the SPS1 and the SPS1UW+ sits in the +Drive, allowing one to use 128 snapshots just like on the Analog Four with OS 1.1.
Wether you “need” all that is up to you…
3 TYPES one machinedrum with no UW , next is a machinedrum with UW - this machine have the same pattern/kit memory and have a fast Ram memory for realtime record samples ( you must save many things in your computer )( … ). the greatest machindrum is with UW and +, then you have the samplefunction uw and a big memory with 127 placess to save a machinedrum projects ( ) -per place 127 sample memory/…
