I´m working in a projekt studio, with a G4 and a motu midi express XT (usb) and every time i try to load a sound from the AN1X editor i get the SysExSize error - can anybody help me to solve this problem???

Yes, get rid of the USB MID Interface; buy a serial port adapter for your G4; get a standard MIDI Interface to run off the serial port. USB and SysEx do not work well together. I've had miserable luck with USB and SysEx on my Mac G3. I still use my serial port MIDI Interface from Opcode and have no problems with SysEx. FYI - I've used OMS 2.3.8 and the USB v1.4.1 drivers from Apple with a MIDIMAN 2x2 v1.6 drivers. Note On/Off events work - SysEx does not :-( Check the Cubase and Logic Mac email lists and you'll find similar stories. The only USB MIDI Interface that I've heard works with SysEc is the Emagic Unitor. Joel (used to be on this list) has used one successfully for SysEx. regards, Jon --- In AN1x-list@egroups.com, Jozej@n... wrote:

The unfortunate problem is that USB just doesn't work well with Sysex (its inherent in the way such interfaces implement the MIDI protocol. i.e sysex tends to get concatenated together, due to the bandwidth discrepancy between USB/MIDI and the lack of end to end handshake. The net result is that the receiving device cannot respond to fast enough!) You may not see this problem if you are only sending short sysex packets (such as tweaking a knob on the An1xEdit interface). However for patch dumps the AN1x uses large numbers of huge sysex messages.....and these must be correctly timed for the device to respond correctly. I believe some manufacturers are starting to manage the USB timing problem within their drivers (i.e. by internally timing how long it 'theoretically' takes to send a message before reporting to the application that it has gone.....or by providing some additional software handshake protocol over USB). However I have yet to see any such interface that is 'rock solid' for high bandwidth MIDI in a multi device/multi application environment. hence the only reliable solution is to get a standard serial MIDI interface.

It's been in the waiting for quite a while, but the newly announced Korg Trition Rack has mLAN support. Now that is a good sign. My humble AN1x would still have to work with good old MIDI. I'll have to wait how to combine it in my current setup. - Peter

Yes I think we will (at last) see some mLAN products this year. Unlike USB, mLAN handles the MIDI protocol correctly. It effectively divides the full mLAN bandwidth into multiple streams at the correct MIDI bandwidth....so it looks like you have a whole bunch of MIDI ports with each operating at 31.25Kbits/s. In this way it overcomes the bandwidth discontinuity (and thus sysex bunching) that USB introduces. Therefore it should be reliable :-) > My humble AN1x would still have to work with good old MIDI.

The only reservation si going to be price....as the Firewire chipset is still (relatively) expensive :-( Regards Gary Email: gary@... http://www.yme.co.uk/yme

OK, so actually it was me who has been doing the screaming. :) > Unlike USB, mLAN handles the MIDI protocol correctly.

I would be happy if I could just tap off the MIDI from somewhere. The AN1x is happy with two inputs on the 01V, but MIDI is another story. (And of course, the 01V doesn't send the excess MIDI from the To Host port to the MIDI outs, so I doubt it will do so if I equip it with mLAN.) - Peter

Hmmm...normally on TO HOST ports you can designate additional TO HOST streams to be directed to the MIDI out ports (On MUxxx units this function is normally accessed from the UTIL/SYSTEM LCD function. e.g. setting Thru Port = 3 directs the third TO HOST port stream via the MIDI OUT. Also one of the MIDI IN ports is routed direct to TO HOST receive). I don't have an 01V for testing, but I would imagine the same is true??? Either way, I will raise your query on mLAN breakout with the 'powers that be' next time I see them. Regards Gary Email: gary@... http://www.yme.co.uk/yme

Late reaction... but better late than never.

There's nothing you can set about MIDI and To Host on the 01V, other than which one you want to use, and what MIDI channel. I've heard mention that you could use high unit numbers (greater than four, I believe) but since Yamaha can't be bothered to write Windows NT serial MIDI drivers, and I therefore have to use the Roland ones that 'only' support two locical units, there's no way I can test this. And it would have been so nice. The 01V only uses one MIDI channel, so I could easily cascade the AN1x. But no, no such luck. > Either way, I will raise your query on mLAN breakout with the 'powers that > be' next time I see them. Oh, I'm not worthy to stand in your shadow. :) Thanks! - Peter
