New unsupported Midex 3/8 drivers available as of (Aug 04, 2011)
https://www.steinberg.net/forums/viewtopic.php?f=150&t=11690

Quote
These drivers support Windows Vista and Windows 7 as well as Mac OS X 10.5, 10.6 and 10.7.

But again, they are completely unsupported! If you want to use them, it is at your own risk! Only modifications to fit these drivers to the new operating systems have been made. There are no additional bugfixes included!

Nevertheless, we hope that some of you can start using their Midex devices again on current operating systems.

Just got a mint Midex8 in the mail today, for a decent price.

https://www.soundonsound.com/reviews/steinberg-midex-8

I've yet to test it thoroughly, but could not resist a teardown.

I don't remember how much this was new, but build feels definitely very cheap compared to the Unitor8/AMT8 from eMagic.

http://www.oldschooldaw.com/forums/index.php/topic,2853.msg10926.html#msg10926

Main PCB just slides in into the plastic case, and is locked in place by the metallic backplate.
Still a little wobbling in the middle of the electronic board, because of its own weight and flexibility, combined to the lack of internal clamping to the case.
Rack ears are just fixed to the side of the plastic enclosure by two screws each.
Not sure the threads would resist a couple of dis-assemblies before being ruined.

motu and emagic built good ones
steinberg always preferred plastic

Mine is a rev2.

Quote
* Midex 8 devices with the Serial Number 336306504 (or greater) needs to run this 1.8.0.0+ driver package because of a new Midex 8 hardware revision. Older versions of this driver will not work with these Midex 8 devices.

A bit cumbersome to install on Windows XP or Win7/10x64, but ok on Win98SE.

I just did a quick test on this platform with an audio engine disabled Cubase VST5.2PB (Paradox) and its notoriously poor MIDI timing with a regular MIDI interface.

LTB works!

The MidiGAL MIDIClock displayed an impressive and steady <1% deviation on the MIDI clock out at 120BPM of the Midex8. It's often in the 0.6-0.8 range actually, @384ppqn.
Best figures I ever had on this plaform.
When switching the Clock Out to the other MIDI interface of this computer (MOTU MidiFlyer parallel), figures are in the +5% range.

Running Cubase 2.8 instead, the MOTU is of course much better (2-3%), and the Midex8 in MME mode rather poor (>4%)

Overal thightness appears very good with the VST5.1PB + Midex8 combination.
It's in the Cubase 2.8 range finally, but with the benefits of a "modern" Cubase classic, before the switch to SX/Nuendo.

More on this later.

It's time to do some promotion for the Midex 8 !


We have actually developed the Midex 8 and LTB for Steinberg.

The root idea for LTB (LinearTimeBase) was initiated by a bug in the Virus
several years ago. Some of you might remember it:
When the Virus Arpeggiator was synced to Midi Clock, the Arpeggiator slightly
drifted away from the original beat; it just went a bit slower than it should.
It was a miracle to me, the only explanation was that either the computer
does not send a small percentage of the Clock messages, or the Virus looses
them.
But how could a system loose just a small portion of messages?
In the Virus this can only happen, when two clocks are sent immediately after
another, in that case it lost the second clock.
But how can two clocks be sent right after another - they should have a
distance of about 20 ms at 120 bpm? A midi timing jitter of up to 20 ms from
the sequencer!!

I tested this, and it was the jitter!

I needed to redesign the whole clock engine in the Virus, especially to have
a smooth tempo measurement for the Delay, to sync it to the clock without
producing clicks by that horrible jitter.
That new clock engine is LinearTimeBase, and it makes the arpeggiator and the
delay unsensitive of clock jitter. It's in the Virus since Virus a.

Later I realised that we could design a Midi Interface, using the same
technic.

I offered this concept to Steinberg, which is now the Midex 8.

The Midex 8 has a better timing than the AMT or Unitor working with Cubase.
When you drive a Midi-Interface without jitter-rejection by USB, this adds
another one Millisecond jitter to the data stream, due to the USB framing.
The Midex 8 archieves a timing accuracy of better than 300 µs, that is the
lenght of one Midi Byte - independent of the condition of the computer or
operating system.
It bridges every timing information, and makes the computer working as a
non-realtime machine.

Try this: Everybody can measure the sequencer and interface timing using the
Virus.

- Switch the Virus LED Mode to " --- ". It's the "secret" timing jitter
measure mode.
- Enable MidiClock Send in your sequencer.
- Set song tempo to 140.
- Start the sequencer.

You will see one of the LFO-LEDs light up, showing that the Virus adapts to
the song tempo. After a while the LED's should stop
blinking. Every blink of the upper LED is a Midi Clock that came in too
early; a blink of the lower LED is a Clock that came too late.

That measurement is not very accurate, it only shows jitter greater than 2-3
ms. Thus, they should not blink when driven by a good system.

On software sequencers the timing is mostly independent of the density of the
arrangement, but this must not be the case on hardware sequencers.
Test your favorite dense midi arrangement on a hardware sequencer. Maybe the
result is a surprise.

Even on high midi traffic the midi clock should be stable, since it has the
highest priority when transmitted by midi.

Reply to me, if you have any questions; this is an interesting topic.

Tell us your results!

Midex were built by BEK Systemtechnik, which also works for Kemper Music nowadays. Maybe they built the Viruses as well?
