Just of curiousity,I was combing through all of Korg's synths & I was amazed at the TR-61's features and it just may be the best keyboard workstation out there for a grand.
It's basically a lower scale version of my Triton Extreme,just with less program patches,no sampler,less polyphony and a SD card slot-but the sound quality is the same and it would serve as a good recording tool for guitarists who like to do the one-man-band thing who are on a budget.
I had Mario in mind when I saw this keyboard.
-64mb of rom(512 programs)
-62 voice polyphony
-89 effects
-16 track sequencer(with pattern sequencing,of course)
-Dual polyphonic arpeggiator
-Sample upgrade option
-SD card data storage
Also,Korg is offering a $100(USD) rebate until December of this year.
