standards - error reading MIDI files into program -

-

i have midi file generated using musescore. plays in windows media player, causes midi reading program crash. i've been using following links me: midi specification , mobilefish midi guide, second 1 primarily. 

4d 54 68 64 = mthd 00 00 00 06 = header length of 6 00 01 = track format 1 00 02 = 2 tracks 01 e0 = 480 delta-ticks per quarter note  4d 54 72 6b = mtrk 00 00 00 86 = length of 0x86 00 ff 58 04 04 02 18 08 = time signature 00 ff 59 02 00 00 = key signature 00 c0 00 = program change (channel 1) 02 b0 07 64 = control mode change (channel 1) 02 0a = running status 40 02 = running status 5b 1e = running status 02 5d = running status 1e ac 78 90 = aftertouch event (channel 13, not applicable in context) 3e 50 = running status 83 5f 3e = delta time (83 5f) , 3e, not status byte (more bytes context): 00 01 40 50

what exists in midi standard i've overlooked here?

this question, wrote, flawed, , i'm sorry people tried me; must have copied output notepad++ incorrectly. however, may run same issues did, i'll write answer question.

whenever running status used, always preceded delta time. may see guides otherwise, such one, http://www.blitter.com/~russtopia/midi/~jglatt/tech/midispec/run.htm, know information on these misleading.

for example:

00 90 7f 7f 7f 00 50 7f 50 00

this wrong.

however, correct version:

00 90 7f 7f 81 00 7f 00 00 50 7f 81 00 50 00

this preceded delta time.

i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution:

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
