When simple view is active, or if the Perform button is on in the Perform/Arp/Effects section in other views, the performance controls subpage is displayed.
There are four envelope control knobs. By default, these are linked to the corresponding parameters in the main Alchemy level envelope (AHDSR 1), but you may reassign these knobs to other parameters. Control-click any knob to open a shortcut menu with a number of useful commands. See Performance control knob shortcut menu items.
Attack knob: Set the attack time for AHDSR1, or adjust the value of assigned parameter or parameters.
Decay knob: Set the decay time for AHDSR1, or adjust the value of assigned parameter or parameters.
Sustain knob: Set the sustain level for AHDSR1, or adjust the value of assigned parameter or parameters.
Release knob: Set the release time for AHDSR1, or adjust the value of assigned parameter or parameters.
