Here is a list of some of the advanced features of the ASQ10:
 
Both linear and pattern style (song mode) recording are supported.
Both "drum machine" style features and sequencer-oriented features are integrated into one universal, easy to use operating system.
60,000 note sequencer capacity
99 sequences may be held in memory at once. Each sequence contains 99 individual tracks, each of which may be output to any one or two midi channels.
The "2nd Sequence" feature allows two sequences to play simultaneously. For example, you play a short, looped drum sequence while simultaneously recording your long multi-track keyboard sequence.
4 independent midi output ports permit 64 output midi channels.
7 sync modes, including SMPTE, Midi Time Code, midi clock, midi song pointer, FSK, pulse wave, and sync to 1/4 note metronome clicks.
SMPTE chase operates without any delays.
2 record modes: "Record" (erasing while recording) and "Overdub" (add notes to existing track) may be switched between at any time.
Sequences may be looped, and recording is possible with real-time timing correction while loop is on. Also, a sequence may be set to loop back to any bar once the end is reached, not just the beginning of the sequence.
"Step edit" feature allows very fast viewing, recording, editing or deletion of any event within a sequence
Versatile editing system allows copying, merging, inserting, deleting of any sequence data.
Each track has an output level adjustment, allowing the output velocities to be scaled in real time while playing.
The velocity or duration values of a group of notes within a track may now be changed globally.
All 16 midi channels may be recorded simultaneously, allowing sequences to be transferred into the ASQ10 in one pass.
Sequence data may be "shifted" forward or backward in time.
"Edit loop" feature allows a portion of a sequence to be looped while overdubbing for fast editing, and allows changes to be "undone"
Sequences may be transposed, either in real time while playing or by altering note data.
"Tap tempo" key allows playing tempo to be set by tapping a key in the time of 2 1/4 notes.
Programmable tempo changes, in mid-sequence or mid-song, are supported. Time signature changes, in mid-sequence or mid-song, are supported.
"Auto punch" feature allows automatic punch-in and punch-out at preset times within the sequence.
2 foot switch inputs allow functions such as PLAY/STOP and
PUNCH IN/OUT to be remotely controlled.
Current position within sequence is always displayed in both bar.beat.clock and SMPTE position.
2 mergeable midi inputs
Timing correction feature maintains original note duration, providing faithful reproduction of original performance, but without timing errors.
"Shuffle" feature provides a useful method of adjusting the "feel" of the timing of your tracks.
Timing correction only affects notes- pitch bend and other controllers are recorded as played.
"Note repeat" feature allows for easy programming of rolls and repeated notes.
Midi "sustain pedal" messages are specially processed so that multiple overdubs on the same track of a sequence may have independent uses of the sustain pedal without interaction.
A specific Midi PROGRAM CHANGE event may be assigned to any track, and is automatically sent out when the sequence is selected.
System exclusive messages, including patch data dumps, may be recorded into sequences.
Includes all drum-related recording and editing features of the Akai MPC60 Midi Production Center.
Large 320 character LCD display (8 lines by 40 characters) with graphics.
Built-in 3 1/2" disk drive.
Fast, easy to understand operation provided by large screen and logical, intuitive design.
Interactive "Help" function provides a full paragraph of explanation for each data field of every function screen.
4 "Soft keys" provide one button execution of many functions without additional dedicated buttons.
The contents of all data fields and other settings are retained while the power is turned off, so there is no need to re-set commonly used parameters each time the power is turned on.
Large memory capacity - 512K bytes RAM, 256K bytes ROM.
Very fast internal 10 MHz 80186 16 bit computer.
Small, portable design - fits easily under your arm.
