I’m using the pitch block for down tuning a lot, Eb, D, C and low B.
When playing heavy distortion, it’s ok and if it’s a live situation nobody will noticed any difference.
As low as you go, the darker the sounds gets (distortion).
When playing clean chords, the sound tend to “break” or “miss” partial notes…
I can’t really explain, it’s like the sounds stutterers a little, it doesn’t sound smooth, like a one piece of chord / sound, you hear and fill something is not as should be, even in live situation.
I sometimes find myself strum harder to get all the notes out properly.
Another thing I’ve noticed is, the less you load the CPU, the better the tracking / no lag is.
If you are using a heavy preset, many blocks / CPU is in a higher %, there will be some delay and you will notice it.
Bottom line, it’s a very good and quick solution for live if you don’t want to carry too many guitars and swap too much but it’s not the best.
