Stage Setter 8 MIDI Control

Former Member

I've written a Windows application to control the Stage Setter 8 via MIDI and have run into a curious issue. I have noticed that if the Stage Setter 8 does not receive any MIDI messages for a few seconds, all of the lights will turn-off. In other words, I can send all kinds of Note-On, Note-Off data and the unit and lights will respond appropriately. Yet, when there is no Note-On/Note-Off activity for a few seconds, all lights will switch off. I've been sending a dummy message every few seconds to alleviate this problem, but that seems like just a band-aid. Is this normal operation or am I doing something wrong?

I don't have any light controller, but I think your problem is about the Active Sensing feature of MIDI.

"The Active Sensing signal is used to help eliminate stuck notes which may occur if a MIDI cable is disconnected during playback of a MIDI sequence. Without Active Sensing, if a cable is disconnected during playback, then some notes may be left playing indefinitely because they have been activated by a Note On message, but the corresponding Note Off message will never be received."

So try to send an Active Sensing message ("FE" in hexadecimal) from your program, one or two in every second.

Hope this helps.
