I want to Synch/Start/Stop/Record Studio one 5.3 with Yamaha PSR S970 to be able to (S1, or Yamaha Clock controlled) Sequence/Record sequenced Audio & Midi Data from External Synth i.e Yamaha PSR S970.

This can be done with Midi Sync with external DAW with AUDIO output as AUX from Yamaha Keyboard together at the Same time. but i am unable to achieve it yet.

Pressing Start/Stop or any Buttons on Yamaha Triggers Multiple buttons/actions on studio one.
Please help if anyone has done this before on STUDIO ONE (Any Versions)
I asked this Question from Presonus Support and this was their Response
Hi Saaim,
Thanks for contacting PreSonus Support.
You may want to set up the keyboard as a control surface as well as a keyboard if the keyboard will support HUI or Mackie control modes. You will want to consult the user manual for the keyboard or the manufacturer's support team to check that.
Here are the instructions for setting up a control surface:
To set up a Control Surface, do the following:
In the Options/External Devices menu (macOS: Preferences/External Devices, click on the [Add...] button.
Choose your device from the predefined device list. Set this to New Control Surface if you do not see your device in the list. If set to New Control Surface, you may wish to type in a Manufacturer Name and a Device Name in the appropriate fields. This makes identifying the Control Surface easier.
Specify the device to which the Control Surface is sending and the device from which it is receiving via Studio One. Select your MIDI device driver name from the drop-down menu for both Receive From and Send To.
You do not need to specify the MIDI channels your Control Surface should use, as control surfaces use alternative protocols, such as Mackie Control, to communicate with Studio One.
Your Control Surface is now ready for use in Studio One.
For more information on using Mackie Control devices with Studio One, see Mackie Control.
If this is not a viable set up then you will have to try manually depressing play/stop buttons on both devices.
You may also be able to export the MIDI files from the keyboard's sequencer, if it has one, and import those into Studio One and then you will need to assign them sounds and instruments.
Best Regards,
