Nasty Latch issue

I change the MIDI Source to MIDI IN - Mono Latch, enable the green Latch button, and check to make sure my Trigger is manual start/stop.

Now I play a key. I see the note is indicated as received by the DAW, but Unify doesn't start playing. If I repeat hitting the note, randomly at some note it will start. It won't stop if I press the key again, I have to hammer the same note about eight times before it turns off again.

What I expect it to do (in the case of drum patterns) is start to play when I hit the note once the first time, and stop again when I hit the same note.

I shouldn't have to hit the same note over and over again to get it to work right?

Thanks for the reply!

No, you shouldn't have to hit notes repeatedly to get latch to work, but I suspect something else is preventing your drum loop from playing.

You probably don't want to set Unify's Transport trigger mode to "manual start/stop" if you want to start a drum groove. Try setting to anything else, or simply start the Transport running. (Note if you have "follow host" turned on, Unify will basically ignore your trigger mode selection anyway, and just follow the host Transport. If follow host is on, try turning it off.)

What are you using to play your drum pattern? MIDIBox? BlueARP? Something else?

@getdunne Thanks for the quick reply. I have tried the plugin in Standalone, and also in the Ableton DAW. I get the same results no matter what Trigger I use, and despite whether "Follow host" is checked or not. It also behaves this way no matter what plugin I'm using (MIDIBox, Sine Wave synth, Guru Sampler).

I made a video showing the problem:

Thanks for the video, but I'm not sure what I'm supposed to be seeing in it.

@getdunne The little green light goes on when I play a key. You can see me playing the keys and latch randomly turning on and off.

I just figured out how to actually play the video and hear the sound. Whatever you used to host it has some kind of strange preview mode where it loops the first part over and over with no sound, and at first I thought that was all there is.

You need to check your MIDIBox settings. It sounds like you started with the BPM DRUM - Chaos Simple Street patch from Cloud City, but I think you may have selected a different MIDI file because the groove I'm hearing doesn't match any of the tracks in that patch. See the attached image, where I show the MIDIBox GUI at the same time. Please redo your movie (can be quite short) with MIDIBox showing. If the progress ribbon at the top isn't cycling, you know MIDIBox isn't triggered. The bottom menu being set to "Loop/Key" is critical -- it means "loop while a key is held down".

What kind of MIDI keyboard are you using? I'm wondering if it might somehow be double-triggering. If you want you can put an instance of the built-in MIDI Monitor on the layer, and drag it so it's to the left of MIDIBox, showing the actual MIDI that's going into MIDIBox. Then open the MIDI Monitor GUI and strike a key -- you should see one Note-on event followed by one Note-off event. If you see multiple Note-On events, that could be the cause.

@getdunne Thanks for the response. For a I minute I thought maybe you assumed I was nuts, and forgot all about me! It turns out that my MIDI Keyboard which is a Novation X-Station 25 Key controller/KS synth was acting crazy and sending out crazy MIDI. I plugged in my M-Audio Keystation 61 key and all the sudden everything behaved the way I expected it to. I'm glad to say it was a quirk with my MIDI controller and had nothing to do with your awesome software. Now I can fully enjoy the latch feature!!
