Re: [CZsynth] Speed of sysex transfer

2013-08-25 by Summa

Hi,

I haven't watched all the communication about that topic yet, been a 
bit busy lately, so the approval of new members messages tend to be a 
bit slower than usual...

It's a "clocked" interface with a _fixed_speed_, that way MIDI 
communication can't be faster than this, even so some manufacturers 
establised a faster MIDI communication between their own devices and 
MIDI over USB and Ethernet might be faster too. Still older synths 
can't keep up in case computers using the full midi bandwith 
especially without pausing between the blocks.

Other than that, some interfaces tend to have problems with sysex, 
especially the noname USB class compliant ones. Here's a link to a 
MIDI Interface Sysex black-/whitelist (link at the top)...

Sysex wise I tend to use my Roland (Edirol/Cakewalk) UM3EX/UM2G 
(Vista/Windows7) MIDI Interfaces, 4x Unitor/AMT8 (98/XP) and a 
MIDIsport 4x4 (98/XP)...
Other than that I avoid class compliant interfaces especially within 
Windows...

I hope this helps!
