It is possible
that the devices have different buffer sizes, so that
sending multiple MIDI messages at once is more difficult. Have a look
at the respective values of wMaxPacketSize that are shown in the output
of "lsusb -v". Furthermore, the devices can have different internal
buffers.
Hi Clemens,
Thanks for the information. The report from lsusb indicated that these
values:
wMaxPacketSize 0x0020 1x 32 bytes
For me it's "wMaxPacketSize 0x0040 1x 64 bytes", is there a
boundary value that must result in jitter?
