Device Setup:

The current version of the MIDI Baby Editor will work with this beta version.

ToneX One doesn’t actually support MIDI commands at all, so we are communicating with it using its native protocol. Some typical “MIDI-like” commands are available, and so we have mapped those to normal commands for the purposes of communication with the Baby series. If you send a standard Program Change message between 0 and 20, the Baby will convert that into a “select preset for Slot C” command for the ToneX. ToneX will then load that preset into the slot and you’ll see and hear the change. Likewise, CC102 will bypass (0) and engage (127) the ToneX, CC93 (127) will tap tempo. Tap tempo is special, since ToneX doesn’t really support this in the way you’re used to. Instead, we calculate the BPM based on your tapped tempo and then send that BPM value over to ToneX. The result is the same but the method is a little complicated so we just keep it all hidden! Note: if you have the MIDI clock enabled on the Baby, we’ll use that BPM instead and no CC messages are needed.

MIDI Baby does not have dedicated control assignments like DMC.micro, so you’ll need to add in actions to control ToneX one. Here are some examples:

Select program 1-4 with LED indication
