Unwanted MIDI data appearing in Sonar Professional - Solved

Hi Paul

These vertical lines have randomly appeared on my timeline. It seems wheel messages are randomly inserted. Can you help me please?

James

I received the above message from James and we arranged to connect later that day. Once we were speaking on the phone and had our remote connection set up via AnyDesk, James showed me the problem. As he was recording his MIDI parts in Sonar using his controller keyboard, he was noticing small changes to the sounds of his synths randomly occurring. When we opened the MIDI editor in Sonar, we could see the that these changes related to small MIDI messages that were appearing in his MIDI recordings.

I had worked for James recently, helping him migrate his studio setup to a new PC. I knew that James had a relatively simple setup with just one MIDI input device, an Alesis V49 controller keyboard and this was likely to be the cause of the issue.

In recent years, I’ve seen problems with budget MIDI controllers made by brands such as Alesis and M-Audio having issues with the pitch and mod wheels sending data when not being touched. This is caused by a fault in the sensitive electronic sensors that records the mechanical movement of the wheels. I saw this exact issue recently with another client using Logic Pro and an M-Audio keyboard.

The most likely explanation is a build up of dust around the sensors and this can be easily solved by blowing some air inside the keyboard using a thin nozzle on a can of compressed air. I showed James where he could order a can of air online.

If the compressed air didn’t solve the problem, then there was a fault in the hardware of the keyboard and it would need to be repaired/replaced. Because of the budget cost of the keyboard, replacement was the most likely solution.

James told me he didn’t really use the pitch and mod wheels, so I showed him how he could keep using his keyboard by filtering out the pitch and MIDI Controller information. This can be done simply by unticking boxes in Sonar’s Preferences.

Now the pitch and mod wheel data were being ignored by Sonar, James could carry on recording with his controller keyboard straight away. When the can of compressed air arrived, James could try blowing the dust out and deactivating the filters. James was happy that he now understood why the problem was occurring and that he had two methods to work around the issue.

Thanks very much Paul. Superb help as always! James B

Paul reinstalled all my lost sample libraries, streamlined the storage on my computer so it works faster and fixed my corrupted disk. it took us a couple of sessions and he was friendly and patient throughout. He never made me feel stupid and never over-explained stuff I already knew - in fact he boosted my confidence. Would highly recommend. I've put him on speed dial!

Honestly, if you're in any way stuck in a creative block because of the gear you have, you've more questions than answers about what the best setup should be for your flow, or even if you have very nuanced problems in your DAW/with your gear, the service Paul provides is second to none. Besides being an extremely nice guy, he knows his stuff and takes the time to understand what you want to get out of each session and makes sure all is good to go! Can't recommend him enough!

 Trustindex verifies that the original source of the review is Google. Paul provided as stellar service, worth every penny. I came to him with a genuine issue that was affecting my Logic Pro 11 album project regarding drums and midi maps and he solved my problem most efficiently.  He was patient, courteous, quick thinking and highly knowledgeable. I will certainly consider using the service again and thoroughly recommend Audio Support -
Thank you Paul - you are a star :)

Super knowledgeable, friendly, speaks in easy to understand terms.
Paul is helping us DAW newbies get in the game. Paul got my lost plugin files working again as well as showed me how to find missing wave files for projects that were loading incorrectly. Keep this man on speed dial.

 Trustindex verifies that the original source of the review is Google. Paul fixed in around half an hour some midi keyboard/controller problems I have been trying to solve but have had to live with for around two years! He is very knowledgeable and patient and the Any Desk link worked perfectly. I wish I had found his website sooner and wouldn't hesitate to call on his services again.
