"Hiccup" in playback test

[johnahedges]

Hello David, and thank you for your response. I have recently purchased Composer and have experienced this "hiccup" issue over a few configurations. The current config I'm using is a Tbox M3 USB MIDI interface by MIDIPlus with an older Alesis QS6.1. No driver is required. I have the same problem regardless of the Notation file I'm using, i.e. I don't believe it to be caused by the .not file, especially since I've also had this problem with the sample files and other .mid files.

However, the first "Note On event" that you mention could part of the issue since I notice a switch from Program mode to Mix mode on my Alesis synthesizer before a playback begins if I have the synth in Program mode at the initial start of playback, so I will try your suggestion of "recording" a blank measure although I believe I have done a similar thing by starting with an incomplete measure via pickup notes. Anyway, I'll be back. Until then, thanks again.

David, I tried you suggestion about recording an "empty" measure to hopefully prevent the "hiccup" but it didn't work entirely. The second bar, which was where the actual MIDI notes started in the recording, sounded fine, but when I listened with the metronome active on playback the hiccup was still present in the "empty" initial measure. Then when I deleted the "empty" first bar, the same problem was present in the music recorded.
I believe it may have more to do with my old Alesis synthesizer than my interface. I have a new Roland V-Combo VR-09 synthesizer and I am able to get a recording without the hiccup although it hasn't been consistent. I have to be careful about how I initialize my setup, i.e. the order in which I turn things on.
I had said the interface was by MIDIPlus but that's just the name of the Amazon store where I bought it. After investigating further I found out it's also sold by Midtech (https://miditech.de/en/portfolio/midiface-ii-thru-1x1/). I like it since I use my laptop and Composer at two different locations and have the Alesis at one location and the Roland at another but I use the same interface so when I change locations I don't have to change the configuration in the MIDI setup window since the interface is recognized as the same device. I just stick with the General MIDI bank, which both synthesizers have.
Anyway, I'm hoping there is some way of solving the hiccup problem instead of doing a workaround.

David, I have good news! A solution to the "hiccup", or so it appears. When I originally set up my MIDI device configuration the options regarding System exclusive events were on by default. I didn't change them at the time but it turns out I should have because when I uncheck the option to "send SysEx (events) to this device", the hiccup is cured!
I also unchecked the option to record SysEx from this since I would only use that if I wanted to record MIDI patch changes or effects changes, which I don't plan on doing. If I did, then I would of course need to send those SysEx events upon playback.
Anyway, I thought I'd share this. Thanks for being there!
