Updates: -------- Date | who | desc -----------|----------|--------------------------------------------------- 2005-10-23 | gnilk | Added some stuff 2002-10-16 | gnilk | negative transpose values now displayed correctly tiny information about sequencer/pattern columns Bugs: ----- - Does crash quite randomly, probably due to thread synchronization issues The source is there, change if you want, we dont anymore.. Keyboard shortcuts in trackerview --------------------------------------------------------------------------- General: CTRL-UP switch between pattern/sequencer editor CTRL-DOWN switch between pattern/sequencer editor RSHIFT-TAB switch between pattern/sequencer editor F7 start play F8 stop play In sequencer view: -------------------- HOME move to top position of sequencer END move to last position of sequencer UP move one position up DOWN move one position down RIGHT move one position right, within the column CTRL-RIGHT move one column right LEFT move one position left, within the column CTRL-LEFT move one column left PAGE-UP move 16 positions up PAGE-DOWN move 16 positions down TAB forward one column LSHIFT-TAB back one column DELETE delete data in current column ---------------------------------------------------------- In patternview: ------------------------- F1 octave 0 F2 octave 1 F3 octave 2 F4 octave 3 F5 octave 4 HOME move to top position of pattern END move to last position of pattern UP move add-num up, default this is one position up DOWN move add-num down, default this is one position down RIGHT move one position right, within the column CTRL-RIGHT move one column right LEFT move one position left, within the column CTRL-LEFT move one column left PAGE-UP move 16 positions up PAGE-DOWN move 16 positions down TAB forward one column LSHIFT-TAB back one column DELETE delete note at position CTRL-DELETE delete note and effect at column CTRL-B begin marking of block, use cursor movments to control block marking CTRL-C copy block CTRL-V paste block CTRL-K truncate pattern CTRL-I interpolate effect column at cursor in block, between blockstart fx value and blockend value CTRL-E double length of pattern, use CTRL-K to fine tune pattern length wont look nice if you extend above 255 (0xff) positions, the limit is set to 65536 note editing is classic tracking editor keyboard setting normal notes: ZSXDCVGBHNJM,L.Q2W3ER5T6Y7UI9O0P raised notes: 0123456789ABCDEF special \ note off -------------------------------------------------------------------- Short notes for the sequencer ----------------------------- There exists two types of speeds. The main speed is global for the sequencer each sequencer channel has a pattern. The pattern speed is induvidual for every sequencer channel. This might be confusing at first, but thats how it works. You set the speed for the sequencer then you set the speed in the patterns. ------------------------------------------------------------------------------ 00 | nn xx yy p1 p2 p3 00 00 00 | nn xx yy p1 p2 p3 00 00 00 | nn xx yy... 01 | nn xx yy p1 p2 p3 00 00 00 | nn xx yy p1 p2 p3 00 00 00 | nn xx yy... nn - pattern number for to be player for this sequencer position xx - Tranpose (00-7f positive transpose, 80-ff negative transpose) yy - Effect p1 - Parameter 1 for effect p2 - Parameter 2 for effect p3 - Parameter 3 for effect The zeros are for further use, and should not be used...

Pattern 0 of N in packed form... seqchannel data is stored as: 0 id of channel (which channel is this), 1 channel length (number of positions in channel) 3.. position data in packed form seq pos data is stored as: flag, indicating (bit flags) 0 no data is stored for this position 1 pattern number is stored 2 transpose values is stored 4 fx parameter is stored 8 param1 of fx is stored 0x10 param2 of fx is stored 0x20 param3 of fx is stored 0x40 param1 of fx is stored 0x80 param2 of fx is stored 0x100 param3 of fx is stored flag is stored as word.. number of bytes indicated by the flags (each type has one byte) max is: 9 bytes in the order: pattern data is stored as: 0 id of pattern, important: the sequencer will point to this number 1 length of pattern positions 3 data in packed form... each row in a pattern is stored as: 0 flag, indicating which of the 16 channels that are used... if bit=1 pos data is available, bit 0 = pos 0, bit 1 = pos 1, bit 2 = pos 2.. (bit 0 = 0x01) 4 the position data itself is not packed... if position data is available it is stored as:
