When I first started using Synchron Player (esp. for Yamaha CFX), I really thought it was a big step forward esp. the mixer and the built-in pan and reverb, etc, and the clarify and ease-of-use of the tree structure.
Yet, deeper I delved into the it, more I realized the troubles with the tree design and how much I missed the convenience of the 2D/3D matrix that VI has.
For example, there is no way to jump from SLOT to SLOT (if the SLOT is deep down in another "branch"), simply because I do not have the visual info, and like others have pointed out, it will take a combination of switches (key, CC, etc.) to make the jump (depending how deep down that SLOT is). For VI, it will be at most 3 switching (first for the layer, and second/third for the matrix navigation). Very straighforward indeed.
Maybe there could a way to combine the convenience of a 2D/3D matrix (VI) and that of a tree (Synchron)? For example, maintain the articulation switching mechanism (of the Matrix) while showing certain relationships across the cells with color-coding (like the Tree)?
It will more like the current VI GUI but with the Mixer page added.
Feel free to jump in. Probably some positive thinking would be something we need for this forum and a token of appreciation for the VSL team for the hardwork they put in.
