Midi::sendMessage: Unknown message type. Ignoring it

Developers

I’m sending out a custom Sysex MIDI message via Lua everytime a knob changes a value like this:

local sysexData = { 
    SYSEX_MESSAGE_LENGTH_PARAM_ADJUST,
    SYSEX_COMMAND_PARAM_ADJUST,
    paramHigh,
    paramLow,
    valueHigh,
    valueLow
}

midi.sendSysex (0, sysexData)

Whenever that line is called, I’m seeing this in the debugger (TRACE level):

Midi::sendMessage: Unknown message type. Ignoring it.

I’m not sure what that means. The sysex message isn’t ignored, I can receive it on the device connected to the E1.

Is there something wrong with the way I’m setting up the sysex message?

Does 0 map to PORT_1?

Without actually seeing the data bytes, that is the only thing I can think of.

The globals are PORT_1, PORT_2, PORT_CTRL

I’ve changed the line to midi.sendSysex (PORT_1, sysexData) and logged the variables:

For some reason it seems your first parameter value is 0 and that might be illegal coming right after the F0

Remember - MIDI messages have the F0, manufacturer ID, machine type, command, then data. The E1 handles the F0 … F7 bracketing, but you still need to supply the correct bytes in between them

What machine/thing is the intended target of this sysex message?

The messages are intended to be received by a custom Reaper control surface plugin I’m writing in C++. I’m receiving the messages just fine in the plugin. Do you think that this approach has drawbacks? Do you think it’s related to the unspecific log from the E1?

Do you call your Lua from a function assigned to a virtual parameter?

It is safe to ignore it. I will get rid of the message in the upcoming release.

The Lua function is assigned to a knob. Does that make it a virtual parameter?

I mean the type of message assigned to the knob, like this:

If it is a virtual type, it is safe to ignore it. If not, I will need to know what type of message you have there. I would take a closer look at it then.

Ah yes, that one is set to virtual. So the message is meaningless in my case. Thanks!

I will remove it from the trace in the next release.
