 I've written the article below based on the 16x8+X Novation Launchpad BLM implementation, but whichever BLM you're using, the interface works more or less the same way.  There are many other BLM options - you can build a hardware BLM, you can use an iPad with the Lemur BLM Emulator, or you could use the Windows/MAC/Linux BLM emulator software.
-You should also read the [[http://www.ucapps.de/midibox_seq_manual_blm.html|BLM Section of the Official SEQ Manual]].
+You should also read the [[http://www.ucapps.de/midibox_seq_manual_blm.html|BLM Section of the Official SEQ Manual]].  TK's Official Manual is the authoritative source of info on the SEQ and the BLM, these articles are just meant to supplement the official manual.

 =====Control Buttons=====
 The "+X" in 16x16+X refers to the control buttons.  These are located along the sides and at the top/bottom of the BLM depending on your BLM configuration.

 Since Version 1.1 of the PC/MAC/Linux BLM Emulator software, there is a second extra column of control buttons providing direct access to the START/STOP, view select and ALT buttons.  Prior to V. 1.1, the SHIFT button had to be activated to access those buttons.  Since a user with a mouse can only click one button at a time, the SHIFT button could be activated with the spacebar.
 ====ALT Button====
-The ALT Button was intruduced with V. 1.2 of the PC/MAC/Linux BLM Emulator software to address some of the limitations of a 16x8+X layout (primarily the lack of control buttons and the need to access more than one octave of notes).  It has a variety of different functions, depending on which view you are in.  These functions will be described in more detail below in the sections for each view.

 You'll notice that when you switch tracks using the buttons on your SEQ frontpanel, the track displayed on the BLM changes as well.  And vice-versa:  When you switch tracks using the BLM Track Select buttons, the track displayed on the SEQ LCDs changes as well.
 =====BLM Views=====
+The [[http://www.ucapps.de/midibox_seq_manual_blm.html|BLM Section of the Official SEQ Manual]] has more detailed information on the various views, and which buttons do what in each view.  I'm just supplementing that information here.
 ====Grid View====
+Each column on the BLM in grid view represents a step.  The most obvious use for GRID view is to edit note layers - in this case, each row of the BLM represents the pitch of the note.  When editing notes, pressing ALT+the track select buttons will select the octave that is displayed on the BLM.
+{{:mididocs:seq:gridmodeblm.jpg?200|Grid Mode on a Note Layer}}
+But you'll notice that if you select a different Parameter Layer using the buttons on your SEQ Frontpanel, the BLM display in GRID view will change to a VU-meter type of display.  For non-note Parameter Layers, the columns of the BLM can be used to set the active parameter layer's value for that step.
+{{:mididocs:seq:vumeterblm.jpg?200|Grid View in VU meter mode}}
+**Drum Tracks:** in GRID view, each row represents one of the drum instruments.  Some drum tracks have 16 instruments - if you're using a 16x8+X BLM, you'll only be able to see 8 instruments at a time.  Press ALT+track select buttons to switch between instruments 1-8 and 9-16.
+**Switching Octaves:** Press ALT+track select buttons to change the octave that is displayed on the BLM. (except on drum tracks - see above)
 ====Track View====
 TRACK View displays multiple tracks across the horizontal access of the BLM.  Each Row represents one track.  More specifically, each row represents one Trigger Layer of one track.  By default, Gate is displayed.  You can toggle the selected trigger layer on and off by pressing the BLM buttons.
@@ Line 51: / Line 63: @@
 To select a different trigger layer with the BLM, press ALT+the track select buttons.  OR, select a different triggger layer using the frontpanel buttons on your SEQ.
 ====Pattern View====
+Use the BLM buttons to activate patterns.  Press and hold ALT then press a pattern slot button to save the current pattern into that slot.
 ====Keyboard View====
+In KEYBOARD mode, each column of BLM buttons will play a note, and moving up or down will play the note with a different velocity.  Rows closest to the top of the BLM play notes quietly, and the note will get louder as you move closer to the bottom of the BLM.
 ====303 View====
 View is not accessible on 16x8+X BLM configurations.
