Casio CZ/ VZ/ FZ - Pro Series

It is strange that the dual instances does not work - as long as the "send patch data" sysx is sent it should fire out a response to the other instance.As for latency- there is more than one type - MIDI and SOUND - some of the soundcards use wavetables of around 8mb to generate tones - if sound latency occurs then the sounds will stammer,this - as you say can sometimes be resolved by reverting to the sound chip.MIDI latency causes the data that generates the notes to stack up and then all comes rushing out at once,which causes timing errors in the music - I think - having used Cakewalk plasma that this type affects VSTs too - though apparently there is a buffer adjustment to try and minimise it - my brother explained to me that the MIDI system goes thru about 3 levels of coding with routines calling subroutines and this is where the problem lies - essentially bad programming in the OS (Suprise suprise MSoft) - 
I find no latency in Win98 either with the sound (to the soundcard chip) or MIDI latency to the MPU401.Whilst PLASMA is capable of multitrack samples and VST - the OS makes it nigh impossible to use - Win98 I don't think will support such things - but not having latency problems makes up for it.It does however support REASON,which is great,and has no latency problems either.
That dual instance of MIDIox not working is foxing me.

      Thanks. Already tried the separate instances on MIDI ox but no go. It 

doesent help that MIDI ox is extremely flakey running on XP. I also had 

terrible latency and just ended up using the onboard PC sound chip which 

is OK as my 50 year old ears cant tell the difference and I'm just 

playing around at the moment. Interestingly the latency is severe when 

playing the onboard general midi sounds but VST instruments are suberb.

The OUT instance sends the prompt to send code from the CZ to the PC and the IN instance picks it up using manual sysx dump.Sending sysx should not be a problem unless (1) applies.
