With the recent price drops on the the Elektron Machinedrum and Monomachine, I picked up an Elektron Machinedrum SPS-1UW. I did not see the TM-1 USB adapter included in the box although the online product description at Guitar Center said it would be included. I eventually contacted Elektron via email about it and this is their response.
The TM1 is not included for free with the Machinedrum UW any more. It is a separate purchase and you can get it either from GC or directly from us, whichever you prefer.
The Elektron TM-1 sells for $115 online at BH Photo.
Hopefully, online descriptions of the Elektron Machinedrum will be updated soon as not to confuse consumers and salespersons.
