Hello David,
If any given virtual theatre organ keyboard supports second-touch then Hauptwerk will allow you to trigger it using either:
1. Real theatre organ keyboard 2nd touch key contacts, or:
2. MIDI polyphonic (key) aftertouch exceeding a chosen threshold, or:
3. MIDI note velocity exceeding a chosen threshold, or:
4. MIDI channel aftertouch exceeding a chosen threshold.
... with 1 being the most desirable for theatre organ playing, and 4 being the least (but still usable for some purposes).
It should auto-detect those automatically (automatically picking the 'best' of those trigger types that was heard from your hardware during auto-detection), but you can also configure it manually by right-clicking on the relevant virtual keyboard (e.g. the Accompaniment), selecting 'Adjust MIDI/trigger settings manually ...', and configuring the 2nd touch settings near the bottom of the right-hand settings pane.
Real theatre organ 2nd touch keys have two indepdendent sets of key contacts. For any given key, the second set are triggered (for that key only) only as you press the key down further than normal.
There are actually two types of MIDI aftertouch: channel aftertouch, and polyphonic/key aftertouch. Channel aftertouch is by far the most common, but it affects all pressed keys equally, so you can't use it to play a melody on the 2nd touch ranks whilst also holding down a (non-2nd touch) chord on the same keyboard, for example. Key/polyhonic aftertouch allows aftertouch to be on/off independently for each key.
Hence real theatre organ 2nd touch keyboards, or polyphonic/key aftertouch are much more desirable, but they're only found on specialist, and typically very expensive, keyboards.
Best regards, Martin.
