Real Time Control
The Holiest Grail can send and receive MIDI continuous controller messages, allowing external sequencers to record and automate parameters. The Holiest Grail sends and receives MIDI CC over Channel 1 only. Each slider (except Input Level) has an associated MIDI CC code: CC# 20 Pre-Delay Time 21 Pre-Delay Feedback 22 Reverb Decay 23 Reverb Damping 24 Reverb Diffusion 25 Dry Output Level 26 Spring Output Level 27 Reverb Output Level 28 Bank Selector (CC is not saved and does not affect program load) 30 Footpedal/CV Input Each time you load a Preset, all of the slider values for that preset will be sent out as MIDI CC messages. So you will receive 10 MIDI CC messages every time a preset is loaded.MIDI Program/Patch Change
The Holiest Grail accepts MIDI Program Change messages to load any of the 8 presets. The Holiest Grail receives MIDI Program Change on Channel 1 only.
