Hey Dewald,
Let’s first tackle the price. You can subscribe to the Apple creator Studio and get Logic for roughly $13 US a month. You can pre pay for a year and get it to be a bit cheaper. However if you have some money coming in, you can subscribe monthly when your trial ends and then pay for it when the money comes in and end the monthly subscription then. The subscription should have a 30 day trial (and a 90 day trial if you bought a new Mac or iPad recently that qualifies) so if you get paid in the next 30 days after starting the trial you should be able to get an extra 30 days to 90 days trial.
Regarding Logic and Logic Magician, part of what makes it great is you shouldn’t have to worry too much where your focus is, so long as it’s in the main window somewhere. If you only have the control bar, inspector, tracks area, and or library open you should be fine.
I think part of the problem is you have the mixer visible. Logic Magician Functionality is such that you really don’t need to go into the mixer and the rare times you do its functionally better to open the mixer in its own window with Command 2, perform the task you opened the mixer for and then close it with Command W. The problem is when you open something as a tab or section in the main window, like the mixer with the letter x, E for an editor like the session player editor or p for the piano roll, the focus shifts to that and thats why things like up and down arrow and or at times left/right arrows won’t work. Turn off Logic Magician and close the mixer with x. If you have the control bar, inspector and tracks area visible, things should work find without you having to have your keyboard focus in any particular place. You can press F1 for the tempo, Change it with option dash and option equals, and add shift to move in smaller increments. You can also after pressing F1 for the tempo press Option W to type in a tempo value.
Option Dash and equal or Option Shift dash or Equals should always change the tempo, If you want to type in a tempo however, you will want to press F1 which simply announces the tempo then press Option W to type in a tempo and then press return.
As I said, Logic Magician has a lot of the functionality you would need to go into the mixer for built in with key commands, from adjusting the volume and pan, to adding effects and sends and even adding plug ins to the sends or aux tracks, all without having to go into the mixer. So there is no need to have the mixer open in the main window. Likewise things like the piano roll can be opened in its own window with Command 4 and that is the preferred and faster workflow than using p to open the piano roll in a section or tab in the main window. Things like the session player editor or the Loop browser that doesn’t have the option to be opened in their own window and can only be shown or hidden as a tab or section in the main window, in those cases you can use tab to switch the keyboard focus between the tracks area and the Session player editor or Loop Browser.
So case in point, when you are focused in the loop browser for example the Loop Browser key commands in Logic Magician are active, when you tab back to have keyboard focus back in the tracks group then the usual Logic Magician key commands should work again.
The key command T should usually announce the selected track even in a lot of cases when the keyboard focus is not in the main window or tracks area. Case in point when a plug in window is open or your focus is in the session player editor etc. So pressing the letter t shouldn’t announce that something is not in focus. Could you perhaps provide an example of a scenario of when this happens?
Regarding assistance, there are a few options, Of course booking a one on one training session with me is one of them. However, alternatively in addition to asking questions here you can also join the LogicBand discord, and participate in the chats there. There are also voice channels on the server where myself and others hang out from time to time and chat about using Logic, workflow ideas, and answer questions.
Regarding re-installing the app, any user patches, channel strip settings or plug in settings you created should remain across a delete and re-installation as deleting the app shouldn’t delete those.
Hope this helps, Let me know if you have any other questions.
