Re: A190-4 Reset Issue

2016-09-19 by sj230962@gmail.com

Thanks Dieter...I'll need to check what the ERM Midiclock is sending when it is running, since this seems to light up the reset LED and is perhaps interfering with the reset message that the box sends to the A190-4. However, when the clock isn't running and I try to send a reset

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
