Hi,Hi Luiz.
For Patch change automation in MIDI, are you using the USB to do this or a Midi to USB device ?
I'm trying to find out how to change scenes automatically through a DAW.
If you have any ideas
I either use MIDI-over-USB or MIDI-over-Bluetooth with the Yamaha BT-01, but usually USB.
To change Preset you have to send 2 messages: CC#0 with the bank and PC with the preset. Please check the Owners Manual, there's a "MIDI Reference Tables" where you find the bank and program change numbers for any given preset. For example, in my case if I want to set the preset 414, I need to send a CC#0 with value 3 and right after that a PC 30. The Math is 3*128+30 = 414, where 128 e the constant amount of presets per bank.
To change the Scene you have two options, you can either set a CC in the MIDI Settings of your Axe-Fx III, for example in my case I set CC#34, and then you send a value from 0 to 7, representing scenes 1 - 8 (just subtract by 1), or you can use SysEx for that if your DAW supports it. I usually prefer SysEx, but this is personal preference (and to avoid conflict with my other devices).
SysEx (in decimal, you may need hexadecimal depending on the DAW):
Scene 01: 240 0 1 116 16 12 0 25 247
Scene 02: 240 0 1 116 16 12 1 24 247
Scene 03: 240 0 1 116 16 12 2 27 247
Scene 04: 240 0 1 116 16 12 3 26 247
Scene 05: 240 0 1 116 16 12 4 29 247
Scene 06: 240 0 1 116 16 12 5 28 247
Scene 07: 240 0 1 116 16 12 6 31 247
Scene 08: 240 0 1 116 16 12 7 30 247
On the iPad (Auria Pro), you can send CC#0 and PC at the same time, it will work. This is the CC#0 with value 3 (bank 3):
And then PC 30, which is preset 414 in the bank 3:
I usually send Preset change only at the beginning of the song, because I never use more than one preset per song, and the Default Scene will be selected (unless you change the scene AFTER the preset, in that case put in the next tick):
It's easier to create a region with a single change, so you can copy it to the different parts of your project, or even among different projects. On the bar 49 you can see a new region, this is the Scene for the Chorus, which in the case of this song is Scene 1 (this song starts at a different default scene). At that point I send a CC#34 (this is configurable) with value 0 (scene 1):
When using Logic Pro I prefer SysEx for Scene:
Don't forget to set AxeFx as destination and use the correct MIDI Port.
Hope it helps.
