How to fix rare issues with plug-ins that the scanner could not resolve automatically.

If the software installation failed on Windows or macOS, here's what to do.

This is why you will sometimes experience awfully detuned instruments.

Logic Pro 10.7.9 crashes on Startup

If you have thousands of audio plug-ins, they happen to be re-scanned every time Synfire is started.

The metronome doesn't sound during lead-in (count-in) when recording at the beginning of an arrangment.

Sometimes a plug-in refuses to scan and blocks the scanning process for long time.

In a synchronized DAW, the playhead happens to jump to far away positions instead of resetting to the beginning.

The downloaded installer may refuse to start on Windows 11 Pro

On some Windows PCs the toolbar icons appear as boxes or squares after installation.

If for any reason you are unable to run and complete a downloaded installer (SETUP), or want to make sure the software and all its components are removed, please follow these instructions.

This message indicates that one or more folders on your Mac have restrictive permissions that hinder Synfire from looking up system information.

If you encounter the error message "Initialization Error. Code -7" on Windows, this may indicate a conflict with some security or defense utility.

Drones in your DAW do not show up in Synfire

This strange behavior was observed in conjunction with certain versions of the software "Spyware Doctor", which doesn't seem to like the MIDI drivers being installed. Please disable or uninstall Spyware Doctor while setting up Harmony Navigator.

When running PLAY inside one or more Drones in Cubase, you may experience hanging (dangling) notes.

This message points to another (possibly crashed) instance of the program still running invisibly in the background. Please open the Windows task manager and terminate HN.exe (or SynfirePro.exe). This should free up all locked files and resources. Another possible cause for this (...)

If your startup log reads like this, there is probably a conflict with the ASIO4ALL driver under Windows 7 64bit: Linking to external MIDI libraries exception occured #(3221225477 0) Failed opening MIDI system [exception occured #(3221225477 0)] Failed opening MIDI system [error (...)

You may see a message warning you that the downloaded package "is not from an identified developer". If you downloaded directly from the Cognitone site, you can safely ignore this message.

This error message prevented users from opening Synfire or HN in a few reported cases.

[B0011] User “ ” lacks sufficient permission to run Synfire Pro . It is required that you are a member of the “admin” group, or have the software installed specifically for . The program will exit now.

A message shows up "You can't open the application because it may be damaged or incomplete" when starting HN2 or Synfire Pro on a Mac.

Problems installing a Cognitone product (earlier than HN2 version 2.5 or Synfire Pro version 1.5 only) on your Mac (solution applies to error messages "The MIDI subsystem configuration failed" and "Please make sure Macintosh HD can be written to by the current user").

MIDI output is not sent to an external MIDI port (MIDI interface hardware)

As more and more plug-in manufacturers are dropping support for 32 bit, Synfire now moved to a single 64 bit Audio Engine. New installations and racks will use that engine, while the 32 bit engine remains as an optional choice for a while. This article outlines how to migrate your existing 32 bit projects and racks to 64 bit.

When setting the custom font and image scaling for your high resolution (DPI) display to 150%, some of the phrase editor's mouse pointers may appear garbled.

This may be documented already. This is more of a tip rather than a suggestion.

There's a known issue with Synfire 1.10.8 where on older versions of Mac OS X, the scanner reports plugins not loading correctly.

Under Windows, problems may occur if multiple programs attempt to use the same USB MIDI driver for input at the same time.

When importing a MIDI track with tempo changes, is there any way to get a better resolution of the tempo map in Synfire? If I import a tempo ramp from Cubase, Synfire places 'jumps' at every beat, and it doesn't even begin with the correct tempo value.

Occasionally an anti-virus utility reports a false alarm on Windows, when installing Synfire.
