According to the Application Notes Page my K3 #145 should have an ~8ms rise time. However, viewed on my analogue 'scope the rise time (0 - 100%) is definitely shorter and nearer to 5ms with a similar fall time though with a sharper falling transition edge.
The notes suggest the mod is necessary to enable a future menu selectable envelope adjustment but I don't want to reduce my rise time to a nominal 5ms if it already is around that figure anyway - presumably I will end up with an even steeper leading edge. Anyone else looked at keying waveforms in pre s/n 211 K3s...?
