I am using CCES 3.0.2 and SigmaStudioPlus 2.3.0 with ADSP-SC589-EZ board.

I am facing two issues in SigmaStudioPlus 2.3.0.

1) The simple Gain module does not have the NumChannels option, very inconvenient. And also, you cannot use dB, only linear, also inconvenient. Any plans to change this?

2) Delay can switch between milliseconds and samples. If you enter milliseconds, the resolution is of course limited. if you switch to samples, you get the closest integer number times 1/fs. if you switch to milliseconds again, you get a different milliseconds number than you had before. If you then switch to samples again (without touching the ms number), you get a different samples number than you had before. And so on. The trick is of course to ALWAYS use samples and NEVER switch to milliseconds. Is this really the idea behind the design? I think there must be a more clever way to handle behind the dialog scene, that would be more robust and not causing corruption of the set value.

This has not improved since I had a look on SigmaStudioPlus 2 years ago. I am surprised.

Mistake: I just found that you CAN use dB in Gain, sorry.
