Building on EHXs 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.Includes a 4GB card delivering up to 125 minutes of recording time Import .Wav audio files from PC or Mac Auxiliary Input mixes MP3 players with the loop output Stereo mixdown track frees tracks for re-use Overdub or punch in/out recording Quantize or non-quantize (free running) modes MIDI Clock Sync as master or slave Most user parameters are MIDI controllable USB port enables backup/restore with PC or MAC Standard 9.6VDC 200mA power supply included
