Thank you for having the manual I needed for an older model Aiwa stero I had found on Ebay --- I wanted the Aiwa because I had tapes and cd's but I did not have a manual as to how to operate the system... I found what I needed and it has enabled me to set the system up for my enjoyment.
I wished detailed information of the JBL S310 and here I found it! Very happy with the service from this site!

Basic Operations
Note Latch Mode
This is a performance mode in which a selected range of keys can be set to Latch. A latched key remains on when pressed once. Pressing the key again turns the note off. Latched notes can be useful to trigger loops or repeating rhythmic patterns without having to hold the key. Any range of keys (0-127) can be speci�ed as latch notes. Therefore, you could set a range of latch keys that are only accessible with the keyboard transposed down, so as to be out the way in normal operation. Note that you cannot set a low key number higher that the high key, or a high key number lower than the low key. Note latching is independent per MIDI channel. Notes can remain latched on a given channel while you switch to a different channel, either via direct channel setting change or via patch load. Additional notes can be latched on the new channel. Turning Latch Mode off manually, via the Latch button, will switch off all latched notes, regardless of their channel or the sequence in which they were latched. Latched notes are NOT switched off upon loading a new patch in which Latch Mode is OFF. To turn these notes off, either return to the original MIDI channel and play the same notes again, or manually switch Latch Mode ON and then OFF.
