I may have made some sense of this.
And all the Admin supplied did provide enough information to address most of this...
If Reaper is sending a value of +1 as the admin has suggested might be the case, then....
I "think" I'm sending the right commands because the Kemper is responding how I expect it too. Some of the time (and the Admin is a fool). But what I believe is happening are some circumstances that are leading me to believe I'm seeing something that I am actually not (and the Admin is not a fool after all).
So If I send...
1: C0 0C 00 [Program Change] chan 1 val 11 - I think I'm right, but what Kemper sees is a value of 12 (+1) thus recalling Slot 2 instead of 1 (UNLESS this is the ONLY command it gets. In which case it responds how I think it should. But that is just an illusion because it actually tried to recall something I wasn't expecting, I just didn't realize it. (What it actually did though is still a mystery)
1: C0 0C 00 [Program Change] chan 1 val 12 - Again, I think I'm right but Kemper sees a value of 13 which is Slot 3, which is EMPTY. (So Kemper responds differently yet again, than in the first command)
But this could explain why stuff is coming out backwards. If Kemper sees my command for an empty slot PC#13 (12+1) what actually happens? The Admin states that the command is ignored. If that's the case then the Kemper should just stay at Slot 2 (or the last Perf #, Slot # it was on). But it doesn't. It seems to default back to slot 1 when it receives the PC#13 command.
If it does default to slot 1, that would explain this backward issue I'm having.
1: C0 0C 00 [Program Change] chan 1 val 11 would then Recall PERF 3 Slot 2 (Because +1 is 12)
2: C0 0B 00 [Program Change] chan 1 val 12 would then Recall PERF 3 Slot 3 (Because +1 is 13) But Slot 3 is EMPTY. If Kemper defaults to Slot 1, slot 1 is recalled
3: C0 0C 00 [Program Change] chan 1 val 11 would then Recall PERF 3 Slot 2 (Because +1 is 12)
If Kemper is defaulting to slot 1 when it encounters an empty slot, this string would recall Perf 3, Slot 2, Slot 1, Slot 2 . Which is what I'm seeing. It's backwards of what I think I'm sending. If Kemper was ignoring the empty slot command then I would think I should see Perf 3, Slot 2, Slot 2 (because command ignored), Slot 2.
BUT if all that is true then it is super strange that when I send a single line of :
1: C0 0C 00 [Program Change] chan 1 val 11 - Kemper Recalls Perf 3 Slot 1 As expected.
Why is this Strange? Because shouldn't it be recalling Perf 2 Slot 5...Which is EMPTY? So if Kemper is ignoring the command, then it should stay on the the last Perf# Slot #. But if its defaulting like described above, Then one would think the Kemper would recall Perf 2 Slot 1. AND.. It doesn't do either.
So the Question now becomes. What is Kemper actually doing when it receives a command for an Empty slot? Is it Ignoring it (because it doesn't appear to be) or is it defaulting to the next closest slot with something in it? What is it actually doing? Perhaps the Admin can shed some light here. Personally I don't believe its ignoring the command, But clearly I've been tricked by this machine before....
Regardless, I believe my problem is totally solved by sending with the +1 in consideration (I wont be in front of the Kemper for a few hours to try it)
But in theory..
1: C0 0C 00 [Program Change] chan 1 val 10
2: C0 0B 00 [Program Change] chan 1 val 11
3: C0 0C 00 [Program Change] chan 1 val 10
Should recall Perf 3 Slot 1, Slot2, Slot1.
As I want it too.
Making the Admin spot on about the +1 Value and the true resolution to my ignorance. And he didn't just give up the answer. He gave me all the info and made me work the problem. So now I think I actually understand better and programming the Kemper will be much easier moving forward. So thank you Admin.
