Multimode Bug

Multimode Bug
« on: October 15, 2020, 12:45:19 AM »
Thought I'd post again about this issue.
With multimode on, if you change a program via a DAW or external sequencer the change in program is reflected in the sound/patch but not on the screen. Different sound(program) same number.
This you can imagine makes for an infuriating work flow. Especially when you forget the PC# hasn't changed and you make edits and save.. yep it will write over what it says on the screen.

Hope this makes sense. I'm surprised no one else has encountered this.

I dont think it is a bug as it is standard MIDI multimode. One has to distinguish between patch and sound. The small display does not help. On the Rev2, patches do not have names only numbers. The name on the display is (as long as "Edit Layer B" is not pressed) the name of the sound on layer A. If you press "Edit Layer B" the name changes, but not the patch...

For example I have patch No 8 and on layer A is a sound called trumpet and on layer B a sound called strings.
If I send a program change on channel 1 I can change the layer A sound to piano. The screen reflects this change and displays "piano". If I send a program change on channel 2 I can change the layer B sound to drums. The display does not reflect this change (it is however visible when "Edit Layer B" is selected) but it is audible.

It is important to note that all these changes take place within Patch No 8. This number is always on the display. The program changes did not change the patch itsef, only the sounds within the patch. If I hit "write", Patch No 8 would be updated with a piano on A and drums on B.

This is normal MIDI Multimode and all my other synths operate the same way. Some do have a control channel. If a program change is received on the control channel, the whole patch is changed. The Rev2 does not have this functionality. A MIDI channel can be set and in Multimode, this is the channel for layer A. Layer B is always on a channel one integer higher. If the MIDI channel is set to 3, layer A responds on 3, while layer B is on 4.

The same in other words (cheers LPF83),4704.msg47269.html#msg47269

Thanks for the reply.  What's confusing is that program changes that you would write in a DAW in "regular mode" show up no problem on the REv2 screen layer a and b. As soon as you use multimode, everything changes sonically, but not on the led screen. If you save that sound it will re-write your patch. You may have just explained that to me, but i may have lost the context of your response. Either way it seems like a total workflow nightmare. Which it has been.

Yes, program changes (PC) have a different effect depending wether you are in normal or multi mode.

Normal Mode: PC changes the Patch on top Level
Multi Mode: PC changes the Layer sounds one level down.

Rev2 is not a real multitimbral synth, it lacks a performance or combi mode. You cannot combine two patches on separate channels with two layers each. That would be real multitimbral. The multi mode in Rev2 gives only separate access to the two layers in one patch themself. Which is great by itself. It is a trade off with the program change commands in multi mode. Either you can change the sounds on the layer level or you change the whole patch which changes both layers. Sequential implemented the first option.

With all the limitations I much prefer the solution as it is.
