Some nice ideas. 8) Although I think any changes to the ZPEQ would be very low priority for me compared to others but…as far suggestions of my own (in addition to yours)…
1. Output meter
2. Real time spectral analysis overlayed onto the ZPEQ display.
All very nice just thinking about it but still very low level stuff compared to other features that have been requested on this forum.
Frits appears to have a very clear plan as to what can be done this year or not, which is good to see. He does though add the odd minor request here and there between updates so maybe this can make it into a not so distant update 😉
I would much prefer a simple zCompressor before any changes to the ZPEQ along with a long list of other things 😉
But as you did ask, the two I mentioned would be my addition to your suggestions. 8)
