"E-Mu Emax II 16-Bit Digital Sound System. This model is 2201...
The operating system is 2.14. Included with the keyboard are an OS 2.14 boot disk, the original power cable, the original manual, two MIDI cables, two 1/4" audio cables, and a padded gig bag. The serial number is 0500641.
The E-Mu Emax II is a 1MB mono 16-bit sampler. Its maximum sample rate is 39kHz but it can play back samples created at 44.1kHz. The filter is 24dB/oct and, while digital, sounds as good as analog. It is also controllable in real-time, which at the time was a major breakthrough. The Emax II also has very robust SCSI implementation that makes it compatible with many external drives (Syquest removable media, MO drives, CD drives, and hard drives with a maximum partition of 540MB). It can send and receive clock signals. When slaved, it accepts 24, 48, or 96 ppq with pulses at least 1ms wide and 1 to 5 volts. When sending clock, it sends 24 ppq at 5 volts and 6ms wide.

The sample time on the Emax II with 1MB is 26.1 seconds (20.000kHz), 23.7 seconds (22.050kHz), 18.9 seconds (27.778kHz), 16.8 seconds (31.250kHz), & 13.4 seconds (39.0625kHz).There are also some undocumented, hidden features on this keyboard, available by selecting the master module. Select it and then choose option 9. Then choose 9 again even though only 1-8 are offered as selections. When prompted for a password, enter 3629 (EMAX on the touchpad). Here are the undocumented functions. Experiment freely!
