While playing with Sonokinetic's Toccata, I was thinking about a way to simulate the way its stop selection method works in VI PRO.
Toccata has two sets of keyswitches: one on the left of the playable range for the lower manual, the other on the right for the upper manual. Each keyswitch is an on/off switch for the corresponding stop. Pressing more keys at once turns on/off the corresponding stops at once.
With Vienna Konzerthaus you can't turn individual stops on/off via keyswitches. But you could simulate a behaviour similar to the one seen in Toccata.
For each manual, prepare a matrix including twelve cells on the X-Axis. Each cell can be selected with a keyswitch. The first row includes only the basic stops, mutually exclusive. For example,
- Principal 16', Bordun 16', Principal 8', Gedackt 8', Hohlfloete 8', Flute harmonique 8', Gemshorn 8'', Nasatquinte 5 1/3', Octave 4', Reedpipe 4', Viola 4', Superoctave 2'
Then, since the modwheel is of no use for dynamics, you can use it to select cells on the Y-Axis. Each cell on the Y-Axis includes combinations of stops, building on the base one on the first row. The more you push the wheel forward, the richer the combination.
So, for example, on the first cell you could build this way:
- Principal 16'
- Principal 16' + Bordun 16'
- Principal 16' + Bordun 16' + Principal 8'
- Principal 16' + Bordun 16' + Principal 8' + Gedackt 8'
and so on, up to filling all the eight slots of a cell. Combinations will not be a simple buildup of stops in a list, but a carefully crafter set of stops with musical sense.
Maybe you will not be absolutely precise in what you select with the modwheel, but you can keep the Advanced view open, and check the selected stops.
