If your audio interface is used by multiple audio applications at the same time (including two or more Gig Performer instances), don’t use different sample rates. If the sample rate is not the same, you will hear audio out of tune, audio pitched down. etc. (example, KB article)
 MIDI in (OMNI) block
Don’t use the MIDI In (OMNI) block if you are using virtual MIDI ports. Why? Well, when you send MIDI events into a virtual MIDI port, the events will be sent on through that virtual MIDI port’s output, but because the MIDI In OMNI block listens to all incoming MIDI messages, it will receive messages from virtual MIDI ports as well. So as soon as you send out a single event, it will feed right back into the MIDI In OMNI plugin and sent out again (feedback loop). So if you plan to use virtual MIDI ports in your configuration, use specific MIDI In devices rather than the MIDI In OMNI block (more info).
 Uninstalling Gig Performer before the update
Scenario: Gig Performer is running fine on your Windows computer and a Gig Performer update becomes available – but before you update, you uninstall your current version or an automatic third-party uninstaller removes all references to Gig Performer.
Per this blog: “Don’t do that! We repeat, don’t do that!”
 Gig Performer instances
Don’t open the same instance twice as both opened instances will respond to the
same MIDI and OSC commands and changing any settings in one of the instances will
change it for both, but only one will get the change immediately (more info).
 Keyboard splits
Don’t create splits directly on your keyboard controller - that could even be dangerous and lead to stuck notes (more info).
If you have a particularly high resolution Windows tablet, it may be that some plugin editor windows are displayed too small. You can address this by adjusting Windows scaling behavior. Click here to learn more.
Sadly, not everything scales. I’m running Win11 on an excellent 17" 4K laptop, scaled to 200% (back down to 1920x1080). Some apps don’t scale and are almost impossible to read. I had been trying to find a decent 32" 4K monitor so I could switch back to no scaling, but those monitors are stupid expensive. Plus, I don’t really have the desktop space for one.
Liberally comment the code you’ve written. Otherwise, you’ll come back to it in a few months and forget completely what you did and why (source).
 Create a backup
Besides an operating system backup, Gig Performer allows you to easily export certain data that you may want to keep safe. Read this blog article to learn more.
 Reboot your Mac after updating an AU plugin
Generally, if you install or update an AudioUnit plugin (Mac only), you have to log out or possibly even reboot your computer before the updated AU becomes visible (source).
 Install 64-bit plugins and note the install path
VSTs may come as 32-bit and 64-bit versions. Uncheck 32-bit versions and note the location of 64-bit ones; after the installation, add the locations to the Plugin Manager.
 Steer clear of plugins that require weekly or monthly authorizations
Most likely you are not connected to the Internet while you are performing; if such a plugin decides to “call home” while you’re offline to authorize itself - it will stop working. Examples: link, link.
Help! What should I do if Gig Performer crashes immediately on start up before loading any gig files or plugins? Every once in awhile we have users who have a Windows OS update installed and GP stops working after the update. Since it crashes on start up before loading any gig files or plugins it can be hard to figure out what is causing this and very frustrating, and it’s often not caused by a plugin. The absolute BEST thing to do is try to run Gig Performer in SAFE MODE (Windows). See the link below to the discussion where one of our intrepid users - LUCASCURTIS - refused to give up, how he did it, and what he found.
I have never cleaned my connectors or experienced any moisture problems (except when I play outside but clean everything before putting the equipment away).
On the other hand, all my cases, bags, or flight cases contain desiccant bags that I change regularly. I buy them in packs of 50.
Prevention is better than cure.
Good advice! Prevention is definitely a great idea, but that equipment is spending time serious time outside, what happens inside the case won’t matter much. Many of our gigs are outside, in FL beachside. Probably more severe under these circumstances.
That’s why I said that when I play outside I clean all my connectors afterwards, to avoid humidity and dust accumulation.
And I do it every time I can (not just once in a while) when I go home, to a hotel or whatever: it takes more time but it’s also called prevention.
I also remain sceptical about cleaning products that add a so-called protective layer. It invites us to be less concerned about systematically doing the work ourselves.
