Hi Thcb,
Given your post is over 12 months old, and you last logged in just after you posted, I am not sure you will see this reply
If not, nonetheless, maybe this will be useful for someone else in answer to your first question:
Is there way to do following stuff with PSR-SX900 and Logic Pro X and if yes, any idea how? I haven't had any success yet.
1. Use PSR instruments with Logic, so if I export midi from my keyboard, can I somehow use PSR instruments in DAW or is only way to export the actual audio track?
I don't use Logic Pro, but I do use Cakewalk with my SX900. I imagine the principles will be the same.
When you say "export midi from my keyboard", I assume you mean that you have used the Quick Recording or Multi Recording option in the SX900 to record MIDI, and have saved the MIDI file onto a USB stick to "export" the file onto your Mac running Logic Pro. All DAWs then allow you to open the MIDI file for things like editing.
I also assume that you are familiar with how to connect the SX900 to your Mac via a USB cable, and that you can see and select the SX900 as a MIDI controller. For e.g., in Cakewalk I see the SX9900 under Preferences -> MIDI -> Devices, and select this for both Input and Output.
I have then used Cakewalk to edit and playback the MIDI tracks via the SX900. This means I hear the MIDI playing through the SX900 speakers, and can therefore hear the PSR instruments.
In your DAW (Cakewalk, Logic Pro, etc) each track of the MIDI file can be linked to a PSR instrument. In Cakewalk, for each track there is a Channel, Bank and Patch (or PSR instrument). If you have imported the MIDI file, the Channel, Bank and Patch settings for each track should already be there. I normally find, in Cakewalk, that I don't need to make any changes to these. As long as the SX900 is my default MIDI controller, as per the above preferences, all playback in the DAW will be output via the SX900.
I sometimes use Cakewalk to change the PSR instrument, which I achieve by changing the Bank/Patch setting for the track. This can get difficult unless the DAW can import SX900 instrument definition files, for which there are some available in this and other Yamaha forums. This makes it easier to find the PSR instruments you want from the SX900 voice data list.
I hope this helps. Kind regards,
Plutogenie
