Master "Program Change" Up/Down feature


#1

Hello,

Sorry if the subject has already been discussed but I could not find a suitable answer on the forum, neither on the wiki.

I have entered the following settings in the midi section of the web conf tool:
Master MIDI channel: 1
Master Program change-up: CC#16
Master Program change-down: CC#17
Master Bank change-up: CC#14
Master Bank change-down: CC#15

First of all, I don’t know exactly what is the purpose of this up/down PC. Is that for snapshots or regular presets ?

Anyway, when I use the related CC commands from my controller, nothing happens.

Am I doing wrong ?

Cheers,
Claude

Master means Zynthian. So if you set the master channel to 1 you should be aware that you should not assign a layer to midi channel 1.
Further more program change means snapshot change, yes.


#3

Thank you Markus for this info.

So I would need another controller to work as a master in order to use the program change Up/Down ?
Is that because my snapshots are all using channel 1 that the program change UP/down is not working (also sent from channel 1) ?


#4

The snapshots have numbers. That’s kind of the program number.
How does your snapshots structure look like?
I am not quite sure what you try to achieve.
Program change of the snapshots or of one of the instruments on the layers?


#5

I have snapshots presets within several banks.
My post was originally to get the PC up/down working. So I expect the next snapshot to load when I send the dedicated Midi signal.
Then I was just trying to figure out why the program change up/down commands had no effect (on channel 1).


#6

Can you send us the output of the command tree?
I don’t quite get the difference between your 2 sentences.
Sending PC up/down on Midi channel 1 means loading the next snapshot in your case as you set the Master Midi channel to 1.

Thank you Markus for your message.
Here is my use case:
I load manually a snapshot.
I send the CC midi command up or down
Nothing happens (the next / previous snapshot of the current bank is not loaded)

Just to be clear, I use decimal values CC number (example β€˜Master Program change-up: CC#16’)

Here are my snapshots for info:
β”œβ”€β”€ 00001-Strings
β”‚ β”œβ”€β”€ 003-pwd St soft.zss
β”‚ β”œβ”€β”€ 004-pwd St + mod.zss
β”‚ β”œβ”€β”€ 005-heavy Str.zss
β”‚ β”œβ”€β”€ 006-pizz.zss
β”‚ β”œβ”€β”€ 007-pizz+trem.zss
β”‚ └── 008.zss
β”œβ”€β”€ 00002-Keys
β”‚ β”œβ”€β”€ 001-piano hard.zss
β”‚ β”œβ”€β”€ 002-Piano dist sustain.zss
β”‚ └── 003.zss
β”œβ”€β”€ 00003-Other pling
β”‚ β”œβ”€β”€ 001-Koto.zss
β”‚ β”œβ”€β”€ 002.zss
β”‚ └── 003.zss

Thank you

Please create snapshots 1 and 2 in bank 1 as well.
Maybe there is a bug.

I created the snapshots 1 and 2.
Still the same issue.
I can see in the logs that the midi signal is received (ex: INFO:root:MASTER MIDI MESSAGE: 0xb01100, where 11 is the hexa value). No actions logs is seen though.
Looks like a bug.
