cakewalk sending random midi CC and note data

[Lewis Dixon]

so, this has been happening a while but has got significantly worse lately. cakewalk seems to be sending completely random midi CC and note data when i hit play/stop, switch tracks, enter and exit the preferences, basically when i do pretty much anything. Iv'e checked my midi inputs, none of them are sending anything (in fact, i disabled all of them and it still happened). iv'e run midiox and it doesn't show anything, so i'm totally lost as to whats going on.

my only potential idea is that iv'e got my keylab mk2 set up as an ACT controller, and potentially that's causing an issue, but it used to work perfectly.

i checked the midi monitor on my argon8, and when i hit play in a completely empty project with no midi inputs or midi tracks, this is the result (2 videos, i hit play then stop in both of them, turn your volume down): https://photos.app.goo.gl/Q6d7ceZnHFdpUMWB8

That's mod wheel data. Cakewalk isn't sending it, it's your controller. Or (less likely) your MIDI interface.

I had an M-Audio controller start doing that, mod wheel data. The circuitry just went funky, and I stop it by disabling the mod wheel data transmission in the controller.

how can it possibly be the controller, if ive got it disabled. and the note on messages arent anything to do with the modwheel.

[Lewis Dixon]

definately nothing to do with the controller, i just unplugged it, and its still happening, when i open projects, start new projects, switch tracks a note on signal is triggered, and when i hit play, what ive mentioned above happens.

So, seems cakewalk somehow messed up my ACT settings, decided that the argon8 should be the output device, removing it fixed most issues.

I was just indicating, generically, that the circuits on controllers can start going flaky as they age and/or get bumped around enough, etc..., since someone had posted about that possibility, as it definitely did happen on my system, until I turned off Mod Wheel data transmission on that controller.

I have had this happen on my PCR-800 as well - this time it was the pan control sending out random CC10 events.  I fixed it with a dab of electrical (non lubricating) contact cleaner in the slider...  

In the OPs case looks like something funky going on with the ACT drivers (or whether you use)

Hi!
Got the same/similar problem and it seems to be the PC it self (Drivers? HW? USB? Memory leak?) that triggers my AKAI MPK to do it?
If I shut down Cakewalk when it's happening I can still see my AKAI MPK mini sending random cc: 73 data (Attack speed) on it's display.
Another possibility is that Cakewalk some how "trigger" the MPK to send data? I don't know?
I re-booted my PC and it disappeared. For how long this time?
If I just restart my AKAI it remains.

Any solution/answer to this yet?

Still most likely a jittery control on the MPK and only coincidentally stopped when you rebooted because the MPK was powered down or the control was bumperd to a non-jittery position. I don't think there's any way for CW to be triggering this given the controls as not motorized. If you have a control assigned to CC73 in the AKAI's setup, try un-assigning it or assigning it to a different CC to confirm. Sometimes physically exercising controls can stop the jittering or they just need to be parked in a different position.
