A ZS3 (SubSnapShot) saves the Zynthian state in the context of the current snapshot. When recalled from the UI or by MIDI Program Change, the saved state is restored. The chain's layout is defined for the snapshot and it can't be changed across ZS3s, but the rest of state is saved in ZS3: bank/preset, engine parameters, mixer settings, clone & key range settings, etc. Snapshots can be slow to load as each engine needs to be started. ZS3 is much faster as the presets are restored and parameters adjusted. Some ZS3 may be slower due to the way some engines load presets, e.g. changing instrument within Pianoteq is slower than recalling a preset of the same instrument.
