Roland is introducing three new drum machines to its TR and Roland Boutique series today, highlighted by the new TR-6S. While one is a software-based version of Roland’s modernized vintage drum boxes, the other two are new portable hardware offerings with MIDI/USB connections for your Mac or PC. The TR-series has been a staple in music production for decades — arguably the series of machines that popularized electronic drum programming — and have in many ways defined the sound of some of the biggest genres over the years (hip-hop, dance, electronic, pop, and more).
