Sending Large SysEx Messages not working. Over 32Kib possible?

Post by MichaelAbletonForum » Tue Mar 28, 2023 7:02 am

Large is relative because I will send 55968 Bytes via SysEx.

I’ve found following restrictions:

I build the SysEx using js - holding the data in an array, send it out will cut it to 16Kib

Sending data as stream to Zl will cut it to 32Kib

Sending the stream to midiout directly does’t work because it seams that internally the midiout has also an restriction to 32Kib between the F7 and F0 message.

Midi monitor shows that’s midi out does not stream, ist collects the bytes, so that throttling the SysEx out is not possible.

How can I sent these 55968 Bytes out of M4L?

Additional Extensions?
