Question

Hi, recently upgraded to V3. I have an Akai MPK88. The keyboard's foot switch setting is set to sustain, and has always worked

before, but doesn't work since the upgrade to V3. I checked, and all current drivers are loaded for the MPK88. I think the settings

are right in Studio One 3....Please advise. Thank You!

Answer 1

You can check via the Studio One 3 midi monitor if your controller is sending Sustain messages. Open the midi monitor in the lower left corner of Studio One 3. Here you will see all in and out midi messages. So pressing a key on your controller, you will see a note on and off message. Pressing the sustain should send the sustain message and you would see it in the midi monitor. It may also show up as CC message 64, the midi message number for sustain.

If you see this in the Midi Monitor, then Studio One is receiving the midi sustain message. If you don't see this, then your controller is not sending the proper message. If you see it and it's not working then there is some other issue.

Check that you haven't set the midi port for your device (MPK88) twice in the Studio One "External Devices" menu. This could cause problems as well such as canceling midi note messages.

Problem Solved:

You may be using a Yamaha FC3A or other pedal with half-pedaling function. My other sustain pedals worked fine except for

the FC3A. To get your pedal to work, try the following:

From the menu, select Studio One > Options. In Options, go to the External Device tabs. Highlight your keyboard and click

the Edit button below. In the Filters area, deselect Controllers and click ok. Your pedal should now sustain.
