Surgeon uses the Electro-Harmonix 45000 looper in what he calls his 'more abstract' (non-techno) live projects, like Anthony Child live and his part in The Transcendence Orchestra. > Currently this Soma Lyra-8 synth is quite important. [...] I'm using it along with the baby version of the Roland SH-101, which does arpeggiated melodies. [...] Both the Lyra-8 and the the Roland are fed into this Electro-Harmonix 45000 looper, which takes either four mono or two stereo loops. Given the steady development of these performances, it's quite effective to layer sounds up into the looper and let them slowly decay as you build in new ideas. It's like this constantly evolving story that you get drawn into. [... The looper is] vital, it's the centre of this setup really. Whatever else I was using with it, I've always used this looper. ['The Art Of Production: Surgeon', Resident Advisor, October 2019](https://www.residentadvisor.net/features/3526) In an accompanying video (0:12) he demonstrates and describes his approach: > It works a lot with the tension and release between the more melodic element, which is the SH-01A [and] the more chaotic and noisy elements of the Lyra-8, which is a synthesizer that I'm a big fan of.

Building on EHX's looper legacy, the 45000 combines the familiar controls of a multi-track digital recorder with state-of-the-art features making it possible to create complex multi-track loops quickly and easily. Each loop has four mono tracks and one stereo mixdown track. The 45000 records non-compressed, 44.1kHz/16-bit CD quality audio direct to a removable SDHC card (4 to 32GB). Each card holds up to 100 individual loops accessed with the optional 45000 Foot Controller (sold separately). Loop speed is adjustable over a two octave range, and reverse recording and playback are also possible. For extra convenience, a built-in metronome to a separate Monitor Out and a Headphone Out are also included.
The 45000 works for me, but I think some people might struggle with the fact that it lacks a screen. For many loop stations, a screen isn't necessary because their functionality doesn't go far beyond the "record, overdub, play" formula that was popularized by the 16 Second Digital Delay back in the 80s. The 45000, however, greatly expands upon that functionality by offering four monaural tracks that can be endlessly overdubbed (as long as you've got free space on your SD card), and a fifth stereo track that is used as a "mixdown", essentially allowing you to record all four phrases together as one phrase, each one occupying whatever position in the stereo spectrum you desire. Interestingly, you can even turn the pan knobs for each track whilst the "mixdown" track is recording, and that motion will be recorded as well, giving your mixdown track automated panning motion. You also have the ability to change the pitch of the loop as a whole with the "tempo" slider, which can give you some very ominous sounds indeed when the "tempo" slider is dropped to its lowest setting. "Reverse" is another useful tool if you're after a more ethereal, less-familiar sound. I find sometimes that, if I record something and don't quite like the way it sounds, or think the melody could use a little something to make it right, I hit the "reverse" button and find that I like the way that sounds better than I liked it playing forwards. Now for the downside: Performing memory changes on the 45000 is difficult without the foot controller made specifically for the unit by EHX, as you must hold down the "stereo mode" button for two seconds, and then hit "reverse" to travel backwards through your saved loops, or "octave" to travel forward. This is a little tedious, but I find it works better for me than spending $140 on a foot switch. That brings me to another feature I hadn't mentioned: the "Octave" button simply shifts the loop down to half-speed, which has the same effect as moving the "tempo" slider down, though I don't think the tempo slider allows for a full octave of pitch alteration. Every looper I have ever owned has fallen short in some way or another, and I think this one is the closest any of them have ever come to being perfect in my eyes.
