VZ-1 and MidiQuest

VZ-1 and MidiQuest

2018-03-11 by flori.weiler@...

Hi all! I'm trying to set up my VZ-1 to communicate with MidiQuest 11. I can successfully transfer all Voices and OpMems from the VZ to MidiQuest. However, the other direction doesn't work. When sending a complete bank from MidiQuest, only patches A-1 to B-4 are transferred, after that, the VZ displays 'LOAD ERROR'.


Is there any setting in MQ that affects this?


I can send single patches, which all land in the temp-buffer, but I'd really like to be able to transfer a complete bank. Any idea?


Thanks,

Florian

Hi,

I never tried to use my VZ-1 with MIDI Quest ;) Might be a timing 
problem,� older synths can be quite sensitive unless you give them 
bigger breaks within the midi stream to process the data.

Anyway, try to ask that question on the CZSynth Yahoogroup (it's not 
limited to CZ Users),� this group is just the files extension of the group.

Best!

I made a chart of what the different errors mean based on my VZ-8m and how to solve them when trying to load sysex files. I have never used MidiQuest, but maybe the chart will help. Someone else posted the info in a compiled set of tips. I will look for that. IIRC one type of error means to check to make sure the channel is set to the same channel the patches were saved as. Another error has to do with the size of the file you are uploading and the type of bank you are set to receive--Voice, Op-Mem, Voice + OpMem. Basically the file has to match the settings.

I will look to see if I can find the chart (either original or re-posted). Do you know if MidiQuest creates and transfers sysex files according to the VZ specs?

Good point about transmission speed possibly causing the error. The VZ receive buffer could be overloaded if the data comes too fast. As you pointed out, packet delays could help.

I suppose the files could be corrupt, too.

If I had the files, I could test them with my VZ-8m that has a dead battery. I can store and use the data; it just goes away when I power down.

Since you are getting a "LOAD ERROR" message, I am inclined to agree that it is  buffer overflow error (data coming too fast).  Either that or maybe the data is corrupt. If the data you are using posted somewhere?  If so, I can try it on a VZ-8m.

From around 2004, re: VZ error messages: 

*Here are the error messages I have been getting when sending VZ sysex
data to the VZ-8m. (See my previous message about channel and data
type matching.)
---------------------------------------------------------------
Message: --TRANS ERROR--- | CHECK SYSTEM!
Problem: Data channel <> VZ receive channel
Solution: Change VZ channel to match sysex file data.

Message: --MIDI ERROR--- | RECEIVE ERROR
Problem: Data type transmitted <> Data type expected
Solution: Select proper data type when loading data type into VZ.
---------------------------------------------------------------
To see the channel and size of data, you can use debug [PC].

i have midiquest for Atari , 
it does not support editing of the vz10m
but lets me dump banks into it for save
....

is this like midiquest for pc?...

just at first glance looks lke maybe you
need to increase memory space for the
dump ...
have you any way to tell if your default
buffer size is large enough within midi
quest to hold all 8 banks at once?

I see that MIDI Quest 11 is current commercial software. So, I'd ask the vendor how to slow down / introduce packet delays going from the software to gear. I cannot imagine they don't have a way to do that and cannot imagine its nor in the manual. I will look for the manual.

Delay between SysEx Messages
Under normal conditions, it should not be necessary to use this parameter and it should stay set to 0.
However, if you are using a very fast iPad with older instruments, it may be necessary to make
adjustments in order to properly transfer SysEx.
Why is this the case? Instrument modules are normally created and tested around the time of that
instrument's release. As computer speeds increase, they are capable of sending individual MIDI bytes
closer together. In some cases, current computers are able to pack the SysEx so densely that older
instruments are no longer capable of receiving it. This parameter allows Midi Quest to be optimized in a
global fashion to deal with this issue.
If is important to remember that a change to this parameter does not take effect until Midi Quest is
restarted
Midi Quest always delays 80 milliseconds between each SysEx transmission and if, during
development, we find a longer delay is necessary, that delay is incorporated into the module's design. In
the case where your iPad is sending the SysEx too quickly for the receiving MIDI device, an additional
delay can be added here. The delay amount is in m

Thanks for all the comments. I've found a solution. Initially, I had the VZ-1 connected to a virtual MIDI port using loopMIDI. I've then patched this port to the physical MIDI port of the VZ-1 using MidiOx. I do this for all my synth, to allow running DAW and Editors/Librarians in parallel. MidiOx is the only tool that communicates to the physical ports, all other applications use the virtual ports.

Somehow this must have been the problem. When I directly connect MQ to the VZ, the communiction works. Surprisingly, I can still run Cubase, MQ and MidiOx in parallel, without any driver conflicts.

Excellent problem-solving. Thanks for sharing the solution you found. I have used loopMIDI, but not in the way you do. I have also used MIDI-OX, but mostly as a diagnostic tool.

I think (not 100% sure) the reason I mainly use MIDI-OX for diagnostics is that when I use it, some internal routings cannot happen. That might even be what your issue was. I never tried to debug it, though.

Again, thanks for sharing your solution.

OT: CS80 for sell

2018-04-02 by Daniel Forró

I have to depart with my Yamaha CS80.

Good shape, everything works. Some maintenance, tuning and setting can make it even better.  Original stand, pedal, score stand, wheels in original soft case. Original Owner’s manual, Service Manual & big folders full of other documents printed from internet.

11111 USD, buyer has to arrange pick up and delivery.

I’m in Japan near Nagoya.

Best regards.
