The pads at the bottom allow for synthesized bass playing directly through the device, and the touch-sensitive… read more drum pad and jogwheel allow you to adjust tempos. The two footswitch inputs make this even easier--one of the inputs can be used for a button that taps to set the tempo, and the other can be used to initiate the drums or other percussive effects ensuring spot-on synchronization. The back-lit LCD screen in conjunction with the jogwheel make sifting through menus a breeze.

"Great Sounding Drum Machine, Terribly Arranged Samples"

Overall:

(see rating details)

The Alesis SR-18 is a welcome update to the now classic SR-16. The sample library is very extensive, ranging from acoustic to electronic sounds. Honestly you could definitely write a full track off this unit and this unit alone with some creative sequencing and the help of a DAW. The SR-18 sounds are wonderfully editable with pitch adjustment up and down an octave, low-pass non-resonant filtering, and, probably most importantly, decay editing. The onboard compression/EQ processing options sound quite good and the reverb algorithms are actually stellar in my opinion as well. They really deliver amazing & lush sounding standard reverbs as well as more washed out or effecty type algorithms. The onboard sequencer is easy to use but a little tiresome. Sequencing from a computer is much better for getting the nuances of off-the-grid looseness. If you wanted to gig with it you could program in the DAW and then record unquantized straight in to keep your original computer programmed feel. The only real downside to this unit, and it’s somewhat irksome, is that the sample library isn’t organized super intuitively. Alike samples aren’t always grouped together so if you’re looking for which clap to use for instance, you can’t just browse all the options in series. Apart from that the samples are really quite useable and even the bass/synth sounds are pretty interesting too even if they don’t have any real-time control. I used to record full drum mixes off this with all the effects… read more going and loved my results. I’ve always sequenced from Ableton but now for finer control I record each drum sample into my DAW after sequencing and load each sound into an instance of a sampler to really get fine control of processing and EQ. Also don’t forget to check the phase of each sample if you choose to do it this way. Sonically aligning your phases will do wonders for a mix when using samples as opposed to analog waveforms which have different phases with each note. Your mix will sound fuller from just adjusting the phase of each sample. You will hear the difference. The SR-18 does so much to enhance the SR-16 that I really hope we get a similar & unexpected leap to what Alesis does in its hopeful next upgrade.
