Program Change in MAIN window question.

Is sending a "PC: Acc. Grand Piano" command (as shown in Midi-ox), when PC is set to "OFF" in the main window, an expectected behaviour? Program change commands aren't sent only when PC is set to "PCseq ---". What's the point of having "PC :OFF" then?

Yes it is another annoyance you have to deal with in a not finished O.S

It is to toggle the sequencer sending the PC as well as from main screen. So it has OFF for no Program changes from sequencer, it ignores them, -- for sequence changes to be recognised in sequencer, and then the numbers will enable the sequence to have a PC assigned when you play that sequence.

Yes, but when PC is set to off, no PC should be sent, right? Right now, the MPC changes program number to the first in a bank every time I start playing the sequence, so it's a bug, right?

No you wnt it set to --

If a DATA wheel is turned to the right when PC field is OFF, "SEQ" will be displayed on the right of PC.
If a sequence is played in this state, the program change recorded as a sequence event will be outputted.
The number on the right side of PC field is Program Change number currently recorded on the sequence.
The program change number will be displayed if the program change is recorded within 384Tick (1 bar) of the beginning of a sequence.
When it is not found within 384Tick (1 Bar), "---" displayed.

thats from http://www7a.biglobe.ne.jp/~mpc1000/os2xl/midi_pc3.htm

So as above it says that if it is set to off then sequencer Program changes are sent if in sequence, so sounds like you have a PC in the sequence.

Sorry looks like I was wrong way round. apologies to you there, I should have double checked for you. So if PC:OFF means that no program change from main screen only ok, So if you have a Program change in the sequencer, then it will still use this. So go [MODE]+PAD 14 to see if you have any PCs in the tracks. If you hit record then I think it will have saved that program change number for that track... so yeah there is 2 places to make PCs, sequencer and from the main screen.

I did check on step edit page before and cleaning all program change messages doesn't help.

As a matter of fact, connect your MPC to MIDI-OX or any other midi monitoring software, turn your MPC on, so the memory will be clean, in the main page set MIDI to 1A for instance, and PC to OFF. Without having anything recorded, push PLAY and look at what you get in MIDI-OX.
I'm getting this message:
00067DDC 4 -- C0 00 -- 1 --- PC: Acc. Grand Piano

You cannot see this PC message anywhere in the MPC but it's being sent, though no recording was done.

It is either a bug or a very annoying flaw..

from the free O.S. as the bugs are making OS2XL not even useable right now.

Well I dont know man, I do not have all these issues and most bugs are sorted quick smart, so can not say I have any where near the same experience you have. In fact I run it 8 hours a day nearly every day so can be pretty certain that its way more stable and un-bug ridden that you make out, thats for sure. Maybe, and im not being sarcastic or condescending but maybe you should check how you updated or just reinstall again properly.
OP maybe something in your autoload ? I do not use midi ox or even a computer. None of my midi gear gets a program change ever unless i put it in. So..... to me it looks like something in autoload or that and you have Bank Select or MSB, LSB info on.
Did you check that? When on main screen and have the program change bit highlighted then [WINDOW] will light up. Hit that and you will see that you have bank select to :YES or maybe MSB info. Get rid of it and see if that fixes it. that should work for you. This is for MIDI yeah just so every one knows that its not drum program changes. Also double your MIDI gear is not sending one to your MPC of course and its just being sent through. So unplug MIDIs in just in case and to help isolate problem, though im sure you have already and that is why we are talking bout it i guess. but just in case you have not give that a go.
Also another thing is that some times you might have the sequencer window set to show note info only and not program changes ect. Double check that to. I have looked for stuff and didnt remember that I have set it to note only. but i noticed eventually. So yeah i am not giving you a hard time just trying to help you isolate the issue in the most logical way. Some one else with any MIDI interface and a computer will be able to see the same thing, so anyone?? To me it seems your end not JJOSXL as I do not have errant PCs going off at all. If I did i could not work on my synths as they would be changing all the time. So yeah hit window and tell me what it says, like I said I think it will have a MSB or LSB and/or Bank Select to :YES, and you want :NO. This is in the MIDI Program Change window yeah!
Good luck Typo. dont get too annoyed with it, and hopefully reinstall will sort you out.

I missed a few updates and everything went down hill fast.I just did a complete reinstall and have my finger crossed.The O.P. is correct that it sends a GM PC
GRAND PIANO CHANGE at the start of the sequence.How it effects your synth is determined by your synth settings. I have three synths and another sampler in my
set up only one synth responds to the command as I can not set it.Thanks for the advice Peace TYPO.

I don't have this problem with my external gear using xl 3.19 on my 2500. What version and system are you using? Does it send PC using all of your MIDI outs? Play and Play Start?
