Hello William,

Thanks for the post. I'd like to help! First, please ensure that you have the latest firmware for your product installed before continuing. You can obtain the latest firmware directly form the Downloads section of each Alesis VI series controller:

This symptom can happen with any MIDI controller. There could be three main causes for this:

1. The most likely cause - The Computer.

For example, background programs may begin running behind the scenes, packages of information may transfer from and to the internet, optimization of programs and background processes need to be adjusted .

You can see the same root problem cause other symptoms often in every day computer use. For example, when a mouse pointer freezes or you click somewhere and nothing happens; when you try to close a program and it takes a long time to close or does not close at all and an error comes up; and when it takes a very long time to reboot your computer.

There are a number of ways to address these root causes, and I have included a great walkthrough guide below to help:

Optimizing Your System, Improving Performance, and Managing Latency

2. A less likely cause - The Cabling.

In years past, a bad 5-pin DIN MIDI cable could cause this symptom too. More than once we have seen a simple MIDI cable switch resolve very troubled users of all of their symptoms.

More recently, with the increased useage of USB cables transferring MIDI information to the computer, the likelihood of the USB cable causing similar symptoms has been reduced. While it is still possible - and we have documented cases where changing the USB cable has resolved similar MIDI transfer symptoms - it is far less likely to be the cause.

Additionally, on my personal computer, a failing USB port was the cause of a ton of difficulty until I was able to determine the root cause.

3. The least likely cause - The MIDI Controller

Here's an easy way to determine if the controller is the cause.

Windows

• Download the free program MIDI-OX
• Run the MIDI OX application.
• Select the Options menu and select MIDI Devices. Make sure to select MIDI inputs and MIDI Outputs for the MIDI controller and click OK.
• Strike a key and release.
• You will see both a Note On and Note Off message. If you see both, this tells you that the controller is sending the MIDI message correctly and the cause of the symptoms is somewhere else.

Mac

• Download the free program MIDI Monitor
• Click on the Sources tab to view MIDI devices. Confirm that your USB/MIDI device is listed.
• Strike a key and release.
• You will see both a Note On and Note Off message. If you see both, this tells you that the controller is sending the MIDI message correctly and the cause of the symptoms is somewhere else.
