Original release notes
Improved the instance list to show instances on the same track horizontally, in the same order as they are inserted on the track. (To show the correct order, it may be necessary to stop and start playback once.) Unlike on Windows or macOS, the instance list currently does not show other plug-ins like Pro-C 3 (due to stricter security on iOS). You can now enter Spectrum Grab mode by tapping and holding on a part of the visible spectrum, just like in Pro-Q 3. To view the popup menu tap and hold on an empty part of the background. Tap and hold the preset button to show a popup menu with quick actions, such as a Save command to easily save using the current preset name. Tap briefly to open the regular preset browser. Tapping the slope value in the parameter value display (for a LP/HP band) will now open a slope menu instead of letting you change the slope by dragging up or down. The new behavior is the same as using the slope button in the band controls. Having a band in Spectral mode will now always introduce the associated latency, even if its Dynamic Range is set to zero. This should fix accidental latency changes during processing, e.g. when automating the Dynamic Range parameter. Note: it is possible when loading sessions created with earlier Pro-Q 4 versions that the dynamic range for a band is zero, but the band is still showing as dynamic because the Spectral option is on, and so it will introduce latency now. In this case, simply toggle Spectral to off to fix this. Fixed a bug that could cause the spectrum analyzer settings to not be saved as defaults for new instances, among other small problems. Small bug fixes and improvements.
