Tools in general

It often drops when using MIDI etc. with a sound tool.

Q)

My Mac and DevSaturn often hang while using the Sound Tools.
It's okay to open and close the window, but changing any value almost always stops.

A)

This is a Macintosh hardware issue that can cause your application to hang if MIDI and SCSI signals occur at the same time.
To avoid this, when setting values, etc., you should cut off the MIDI settings, and when using MIDI, do not let the work such as setting values use SCSI.
