Hi - I'm using the A190-4 as my midi interface, with master clock provided by an ERM Midiclock unit.

When I hit start, the clock starts but the Reset light activates on the A190-4. When I reset from the ERM nothing happens. When I stop the ERM the clock stops (obviously) and the reset light goes off.

Now, the ERM sends the clock pulse and the only other controls on the unit are play/pause and resync/reset buttons. Hitting it during playback works to resynchronise all devices by resetting the song position pointer at the start of the next bar. Effectively this means that any devices which have slipped out of sync are immediately and seamlessly restarted without interrupting playback.

Any suggestions as to what's happening ?

DIN-Sync and MIDI are two completely "different pairs of shoes". 
DIN-Sync is a quasi analogue parallel format, MIDI-Clock is a digital 
serial format. The only thing they have in common is that they use a 
round five pin connector. But even flying saucers and stone age wheels 
have in common that they are round...

You must use MIDI!

The Reset output of the A-190-4 is controlled by Midi Start/Stop messages.
These messages have to be transmitted to the A-190-4. Otherwise the Reset
will not react. Details in the A-190-4 user's manual.

Midi has no realitime "RESET" message available, only start, stop and
continue ! As already said you have to send Midi start/stop to control the
reset output of the A-190-4.
