Boom, Bap, Bass Iconic drum machines have been built by Roland for decades, and Sweetwater’s production pros can confirm that the Aira Compact T-8 Beat Machine is akin to the company’s greatest hits. Hallmark Analog Circuit Behavior (ACB) technology powers the T-8’s engine, bringing you six rhythm tracks that faithfully reproduce the classic TR-606, TR-808, and TR-909 drum machines. For added "oomph," a dedicated bass track pulls from the iconic TB-303 synth, with sawtooth and square waveforms perfect for some acid flavor. Rhythmic possibilities abound, thanks to the TR-REC-powered 64-step sequencer that is loaded with onboard FX and advanced programming. Moreover, the robust suite of interoperative capabilities mean that this bass blaster is ready to rock solo or with the band.
