You should definitely get the OS from the link tonspion posted above, it directly supports Linn.
No, you can't preview sounds.
No, you can't freely transfer data to and from your computer but you can follow a series of steps to have the 60 import 3000 files you have created on your computer.
You really should read the version 3 manual. Copied from the manual's introduction, below...
What Are the New Features in Version 3.1?
The MPC60 Version 3.1 software contains many changes and
improvements over version 2. The major changes are listed below.
Sound Generator Changes
• The former 4.5 second limit on new samples has been eliminated.
New samples may now be as long as available memory, up to 26.2
seconds in an expanded MPC60. Also, it is no longer necessary to
erase all sequence memory before sampling.
• You may now sample stereo sounds. This accomplished by first
sampling one side of the stereo sound, then afterwards sampling the
other side. Then, a new feature resynchronizes these two mono
sounds and converts them into a single stereo sound.
• The new Sound Compression feature squeezes any sound into ½
the memory space, at the expense of lower treble fidelity. If all
sounds in memory are compressed, this effectively doubles available
sound memory.
• You may now load all MPC3000 disk files, including stereo sounds.
However, the MPC60 cannot read the high-density MPC3000-format
disks. To read MPC3000 files, they must first be saved from an
MPC3000 onto an MPC60-format disk.
• Total sound capacity is increased from 34 to 128 sounds.
• The new programs system of sound assignment allows all sound
assignments to be instantly changed merely by changing the active
program number, instead of by loading a new SET file as before.
There are eight programs, each with a unique set of sound
assignments from a common bank of 128 sounds. Unlike SET files,
saving a program to disk only saves assignment and parameter
information; the sounds used by the program are saved as individual
sound files. This allows multiple programs to be saved to the same
disk without redundantly saving sound data as SET files did.
• New Mono Mode parameter causes a voice to restart, terminating
earlier plays. Also, any sound can be set to terminate any two other
sounds.
• Sample editing is enhanced. Now, any portion of a sound can be
copied or removed and then inserted into another sound at any
location. Also, any portion can be silenced or reversed.
• The Double Play feature has been removed. Instead, up to three
sounds can be assigned to play from an incoming MIDI note number
or pad. The sounds can either play simultaneously, switch
depending on note velocity, or switch depending on envelope decay
(to simulate the old hi-hat decay slider function).
• The Best Start feature automatically finds the point within a sound at
which the drum strike begins, bypassing any dead space at the
beginning of the sound which could cause playback delays.
• The envelope decay parameter is now switchable between two
modes: END (same as the old Fadeout parameter) and START
(decay begins immediately following attack).
Sequencer Changes
• MIDI Files are now supported, allowing you to move your sequences
between the MPC60 and an external computer sequencer.
• In Step Edit, the REWIND [<] and FAST FORWARD [>] keys can
now be used to search to the previous or next event within a track.
• In Step Edit, events can be cut and pasted by changing the function
of Soft Keys 1 and 2 from <Insert> and <Delete> to <Paste> and
<Cut>.
• The number of pad banks has been increased from two to four for a
total of 64 pad/bank combinations. The active pad bank is indicated
by a letter (A–D) at the top right of the LCD screen. Also, check the
BANK 2 light: it’s off for bank A and on for banks B–D.
• In drum tracks, drum notes are now assigned to MIDI note numbers
instead of to pads. This provides easier compatibility with external
MIDI devices and allows pad assignments to be rearranged without
affecting sequence or program data. MPC60 Version 2 sequences
are automatically converted from pad assignment to note number
assignment when loaded.
• The Hi-hat Decay Slider has been renamed the Note Variation
Slider, since it can now generate a unique value of either decay,
tuning, or attack for every note, and can be assigned to any pad.
• The 16 Levels function can now provide 16 levels of velocity, tuning,
attack, or decay for every note.
• The Copy/Merge a Track feature (renamed Copy Events )now
permits specific drum notes to be copied.
• The Change Velocity/Duration feature now allows specific drum
notes to be edited.
• The new Shift Timing feature shifts track timing independently of
timing correction.
• The new Edit Note Number Assignment feature permits reassigning
specific drum notes from one note number (instrument) to another.
• The Count In feature can now be set to activate only before
recording.
• The Punch In feature can now be set to Punch-In Only or Punch-Out
Only.
• New MIDI Local Mode internally disconnects the pads from the
sound generator. This is useful when using the pads and sound
generator with external sequencers.
General Changes
• Hard disk save and load operations are now included. (This requires
a SCSI interface kit available from Marion Systems. See appendix
for more information.)
• In order to make room in ROM memory for the new features, we had
to remove all of the help screens, as well as three underused
features: MIDI Sample Dump (SDS), Pulse 96 sync and the “data
changed” indicator above the DISK key.
