It's come to my attention (though I'm not at liberty to go into details) that there are a number of additional features that are currently dormant within the Z4 board. Most of these were either far too esoteric to make it into the final design, or were otherwise too complicated to express using the LED display and scroll buttons. Nonetheless, it's possible to expose these feature via the ZenEdit interface.
Before I begin investing the required time to unlock these features, I'd like to get a sense of how much interest there are in them. These features are definitely for more advanced users, who may or may not need them, so I'd rather not waste time on them if they would not get any use in the real world. So please, chime in with your opinions on these, whether you're for, against or even just ambivalent.
The first two possible features are as follows:
1) Modifiable note duration. When you tap a trigger, the Zendrum presently sends out a note ON message, immediately followed by note OFF. Melodic players may benefit from altering the delay (or duration) between these events -- just like holding down a key on a keyboard. Of course once it's set you're then stuck with that duration, so I would assume it would only be handy when you're playing along to a click, or can otherwise tightly control the tempo so that the note lengths fit the material. What could you do with such a feature?
2) Interchangeable triggers and continuous controllers. So it turns out that any trigger on your Zendrum can also function as a CC, and vice-versa. Would you get any use out of that? One idea may be to have a trigger which functions as a volume control. Tap it, and however hard you hit it will determine the value for the volume setting. Another idea may be a set of triggers that function as program up or down. Basically any CC message available to your module/software could be assigned to a trigger pad. And then of course you can go the other way, and use any of your physical CCs as triggers. In BFD for example, you could have the sustain button send out a MIDI note ON message that you could map as a universal cymbal choke. The possibilities are of course endless, but is there really a need for this?
There are even more features available, but they get more esoteric from there. There also are some questions about whether or not they were completed or abandoned. And some, like hi-res MIDI, are probably not yet ready for prime-time. The two features listed above are well enough for starting this discussion -- at least for now.
So, whatcha think? Let your MIDI nerd flag fly and jump in on the comments!
